Electro-Harmonix Holy Grail Reverb

easy as hell

For all of you suckers that are hunting for high priced boutique pedals from some nurds in the dessert of texas...or you studio shredding dream theater cracks...go and waste your money on a tone anyone has.
I play a 5 year old holie grail in a Plexi from 1969 with a mingled greenback, V 30 pounder cabinet ! And my need for a reverb is great with this stupid littel box. Sound ? Yes I got mine ? Whats with you ?

********. the Acdc input doesnt work seriously, you must put it out and back again to make the "grail" work...also the screws from the input/output get weak every year ! the case is thin as a fishcane.

Never get a question answerd !!suckers

Im a bla bla bla, and i can bla bla bla, also I earn money with bla bla bla, playing since bla bla bla, so im a pro bla bla bla....

I bought this used and to say it is easy to use would be an understatement. There's a three way switch and one knob to control the amount of reverb. It doesn't get any easier then this.

Setup wise, I am mainly playing a Gibson 1958 VOS Les Paul into a Marshall TSL 100 head and Orange PPC412AD 4x12 cab using various other FX pedals both in front of the amp and in the loop. I run the reverb into the amps FX loop which is permanently engaged and it's the only pedal I use specifically with it's own power supply and not daisy chained as this mother draws a lot of current at 500MA's.

Firstly, these pedals seem to be hit and miss for some people. Noise wise, it doesn't add a single bit of noise to my sound and being true bypass, it's transparent. I power both my amp and pedals through a regulated / conditioned power strip which I have always found keeps noises to a minimum + using high quality leads as these two things are the cause of most noise in guitar setups.

As for the sound of this thing, I was blown away! This cheap reverb pedal I bought for ??40 to use with one of my non reverb amps actually sounds better then the spring reverb on 95% of amps that I have ever owned and used (and believe me, we're talking 50+). The Orange Rockerverb and Fender Twin Reverb are the only two amps with a better "spring reverb" that I've heard and this thing has no springs !!! I don't ever bother having the Marshall's reverb on, I just use this instead as it sounds miles better anyhow.

The reverb is very lush and deep but without being completely overpowering like a built in spring reverb when you set the level to high. Not really tried the hall or flerb setting but don't need to as the spring setting was bang on the money for me straight out the box.

It's not the strongest looking pedal in the world but a bit too early to tell. I think it will last as this lives in my pedalboard and is permanently on and never switched off with the footswitch so there's absolutely no reason why it wouldn't last.

I do gig without a backup of this as I don't have another one and if it stopped working mid gig, I'd just engage the Marshall's reverb instead.

Never dealt with them so I'm not going to offer up any rating here.

I've been playing for about 13 years and play in two different rock bands. This pedal is a good match for what I need in a lush clean sound and thick overdrives.

Gear wise, I've owned so many amps, guitars and pedals, I couldn't even start to list them all but recently I've thinned down my collection and the above setup is definately my sound so not really forseeing any changes in that setup in the forseeable future.

If you want a natural sounding spring reverb pedal that sounds better then the other digital pedals from Boss and Digitech etc and doesn't cost the earth then this is for you. I've owned both the RV5 and hardwire reverb pedals and both sound digital and sterile next to the EHX which sounds very natural and clear

If something happened to this, I would definately go out and get another one.

Ease of use was OK. Plug in and away you go. One knob and a 3 way selector switch for Spring, Hall, and "Flerb"? reverb choices. Not much to it

First of all, this is as noisy as you can get. It has the correct power supply and the hiss is louder than the guitar signal. Not easy to get above the noise floor on this. The adjustment knob is useless after about mid way. The effect is beyond useable and sounds fake. No natural sounds from this and what is a "Flerb"? Not a feature I would consider using but I did try it but only out of curiosity.

This not a very well built unit. Thin sheetmetal, flimsy feeling, the connectors don't look to be first rate, and it really has kind of a "cheap" feel about it. Careful not to cut yourself on the edges/corners.

No idea. I returned this before I would try customer support.

I recently bought a head and cabinet set-up with no reverb. I bought this before reading the HC reviews. That was my mistake. Please don't make that same mistake. Read others comments about the sound quality and try this in a quiet setting (if that is possible at the local GC). If you get it home and starts acting up, take it back. Do not be shy about this. It will not get better and you will hear the hiss and hate that you bought it. I took it back and considerd the higher priced gear. There is a reason the others cost more, because they are worth it. This thing? Well, not so much...

Plug it in, set the controls the way you want them, and go.

I use a Tradition Strat copy with a Humbucker in the treble pickup position. I also have 2 Fender Mexican Strats, one with Texas Special pickups. The Holy Grail sounds good with all of them. My amp is a 1966 Fender Concert with 4 10 inch speakers. Sometimes I will hook the Concert up to a 1966 Fender Bandmaster head and a 1964 2-12 Fender Bassman bottom, or a 15 inch Kustom speaker. The Holy Grail spring reverb setting sounds good with all of them.

I have been using it for about 6-7 years with no problems.

Haven't had to.

I play blues-rock. I have been playing guitar since 1965. I would buy another if this one shut down or was stolen.

well, its certainly easy to use-but I'll get right to the main point-only buy this product if you can't afford anything else.For all of the reasons below..

Firstly-is it noisy? yes-constant hiss (and yes, I am using the correct psu.)
effects parameters are breathtakingly poor-and Im not a fussy guy-you can choose from long to super long reverb-the dial for controlling the length of the reverb is poor in terms of incremental scale-seriously lacking and frankly, smacks of a homemade unit put together by an enthusiast..
instead of including a delay/echo as a third option after spring and hall settings, they give you 'flerb'-i mean..i wont waste my time or yours..
I bought mine as a v.good condition ebay find- half price-I would NEVER buy this full price and new.

used it at the 100 club-its been ok so far..

been playing decades.
like i said-dont buy it unless its dirt cheap and you're strapped for cash.

Possibly the easiest to use pedal in the world. One knob which increases the amount of reverb and a switch to chose from there reverb voices. perfect

The sound quality is great, better than the actual spring reverbs in both the marshall tsl 100 and peavey classic 50, much warmer with out losing the colour and characteristic of the instrument used. I mainly use this pedal with a Marshall jcm 800 super bass, orange 4x10 and 1x15 and a fender jazz bass. This effect works well to add atmosphere and huge sound to my band, it loses no bottom end

I love electro-harmonix gear to bits, but i will be honest, this pedal suffers like alot of their other products from poor jack in puts which have had to be retightened regularly and sometimes replaced. This has also happened to my russian muff. I have to say though that their newer products that come in aluminum die-cast enclosures are much more reliable.

never had any problems. always been able to repair them myself

just a great sounding simple reverb pedal,

Super simple to use

I got this pedal as I was tired of the spring reverb crashing in my Marshall amp. And what can I say... I was amazed at how well this pedal duplicates spring reverb in a very natural and warm way. the hall setting is fantastic too. I run it in the effects loop of my amp and it is noiseless and acts like it was a reverb actually built into the amp. It really is quite amazing for a digital set up... it doesn't sound digital or tinny in the least...

The flerb setting is cool, but I don't think you could play for long with it before the novelty would wear off, but it is a cool little thing to have in your arsenal of sounds.

I would definitely recommend this to someone who is looking to add a reverb sound to their amp.

I use it with a Gibson Es 335 and a Marshall on the clean channel and the tone is freakin awesome

A word of advice - the louder your amp gets, the more you need to tweak back how much reverb you are dialling in.....

I leave it on all the time and it sets there doing a very reliable job....

It's in a stury enough metal casing..... not built like a freakin tank like fulltone pedals, but much more sturdy than your average pedal...

not needed

A word of advice - this thing sucks down 500m/a, whiich is a lot of juice and you will need to get a converter to run it with your 9 volt power supply.... but a good guitar shop should have all the accoutrements you need.... :)

Very easy. 3-way mode selector switch (Spring Reverb, Hall Reverb, Flerb) and Reverb knob, which controls the amount of reverb. I didn't rad the manual b/c it was just so damn easy.

Also, this pedal only runs off a power cord (included) because of the massive energy required to power it.

I'm using a Tele, Jazzmaster, and SG through a Deluxe Reverb.

Spring Reverb is OK, but not great. It's not as warm as the spring in my amp. It's not bad, but nothing too impressive. The Hall Reverb is very nice and very lush and ambient. The Hall Reverb is the best feature of the pedal. The Flerb is a flanger/reverb effect and I find it completely useless. I wish they hadn't included it and made the unit cheaper.

I'll admit that I am bias towards digital and prefer analog. Obviously, the HG is digital and it shows. It sounds a bit too thin and unnatural compared to spring/tube tanks. It has small volume cut while engaged, which is common. It also has another signal problem I will get to below...

The biggest problem I had with the HG is that mine would often have massive signal cuts when I turn it on. It didn't start until I about 2 hours after I first started playing with it. The LED would light up but barely any signal would come through. After turning it on and off a few times, it would finally engage properly. I've read that this a problem with many HGs. Some people get units with this problem and some people don't. I guess it's luck of the draw.

If I had a good one, I guess I would feel comfortable gigging with it. However, mine was broken, so I returned it. I love EHX and have several of their pedals but never experienced anything like this before.

Never had to deal EHX. Usually their pedals work like a charm.

The fact that the pedal wouldn't work properly bugged me, but since I wasn't head over heels for the sound either, I just returned it for a refund. I'd rather just fork over the cash for a Fender Reverb tank. I liked the Hall Reverb of the HG, but in the end I didn't think the Hall alone was worth $118.

A lot of people like this unit, but it just wasn't for me. I'm not a fan of digital and the fact that you don't know if you're getting a defective pedal or not does not appeal to me. I still love EHX, so this won't hold me back from getting more of their products. Every company has problems with their products occasionally.

Really couldn't be any easier!. There's one large main knob that adjusts the effects level and a simple switch allows three distinct tones, each of which I find very usable for different styles. This is my second Holy Grail and I'll explain why below. The first (defective) one came with Big Muff directions (???). The (good) one I exchanged it for csme equipped with the proper Holy Grail directions. However, anyone with an ounce of intelligence can figure out how to use it in about three seconds.

To check the Holy Grail out, I used my Gibson Angus Young SG, plugged into an 80's Marshall 4010 Combo with vintage Celestion G12-65 speaker, along with a Jacques Overtube. This is already a "tone monster" combination but the Holy Grail makes it much better in ways I didn't anticipate. The Spring mode with the Overtube just rocks out with violin tone. The Hall mode, run clean through the amp, produces tones reminiscent of the bluesy ones Mike Bloomfield used to pull from his Les Paul. The Flerb mode brings Gilmour's Pink Floyd tones to mind. There is minimal hiss with this pedal and only a very slightly discernible loss in volume when the Holy Grail is employed, in contrast with other feedback I've read here. Solution? Turn the guitar's volume up a smidgen.

Here lies the rub! The first one I bought from Guitar Center had the wrong directions (no big deal) as I mentioned above. The big problem was that the volume cut out substantially on at least three occasions, probably within a total of an hour's use. Someone here, commenting about the same problem, talked about removing the casing and then reattaching it, to find that this somehow temporarily solved the problem. Well, it temporarily did, but I couldn't explain how. When it happened a 3rd time I thought about resoldering the wires but quickly ruled this option out when I considered the money I had just spent on this pedal. However, Guitar Center exchanged it for me without any argument and the second one sounds wonderful and has worked perfectly.

I've never dealt with E-H and didn't have to, since Guitar Center was very accommodating. I do believe E-H would have repaired or replaced the 1st unit for the cost of shipping if that had been necessary, but I can't say for sure because of Guitar Center's good customer support.

I love this pedal with my Marshall, for rock or blues. It would probably work well with Jazz, too, but that's not really my thing. I've been playing good garage band blues and rock since 1964 and still gig every now and then with a band I've been with 17 years now. I've owned other old Marshalls before and have usually purchased Fender Reverb Units (both new and vintage) to accentuate the tone. When I would eventually sell the Marshall, I've always sold the reverb unit as well. As far as I'm concerned, this pedal does the job of the more expensive outboard Fender units for a fraction of the cost and I would buy another immediately if it were lost or stolen. Of course, the key is to purchase one that works properly. By the way, the sales people at Guitar Center recommended the Holy Grail over the more expensive Boss Digital Reverb. I'm glad I listened!!!

Not too much to be concerned with here. The manual explains it all and the three functions, spring, hall, and flerb (light flanger with hall reverb) and all controled by a simple level knob.

KH 203, Holy Grail, Boss NS-2, Peavey 6505+. This combination is perfect for what I was going for. I typically use the flerb setting and use it to thicken up solo sections. The spring and hall reverbs are fantastic but you can't beat the sound of the flerb. I have no idea if it's noisy because I run the NS-2 directly behind it. I had heard a customer complain of a reduction in signal strength while using the Holy Grail but my signal strength remained loud and clear when I turned the unit on.

I just purchased it but I'm sure I won't have any problems with it as I take great care of my gear.

Never had to deal with them and hope I never have to.

I originaly purchased this for a cover band I was playing for and to make up for the fact that my amp lacked a reverb tank. After using it today with my southern metal/hardcore band I found it to be a great way to thicken up my solo sections. I really enjoy the flerb feature and the fact that a power supply is included with the pedal. I basically picked the Holy Grail over other reverb units because I've always been a fan of EH effects.

If you are looking for a reverb to add to an amp like the FENDER PRO Junior, then this is for you. I'd suggest replacing the speaker in the amp first (e.g. Jensen's Alnico 10R), and giving it a chance before changing tubes, but all in all, this neat, simple reverb pedal really does fit the bill.

Unlike some other reverb units, this one does work well with small amps.
My only reason for buying it was to supplement the above-mentioned "Reverb-less" amp. Personally, it serves no further purpose than what I've already described, but I can't see why it shouldn't work well with most amps. It doesn't add anything to what my '65 Deluxe can already do, so I'd suggest checking it in the store with a similar amp to your own. With this modified Pro Junior, it simply sounds terrific, especially on the HALL setting, but there's no doubt that the JENSEN speaker vastly improves the overall sound anyway.

It looks sturdy enough, and the company's name is built on a pretty solid foundation. However, it does have a little hiss as some other reviewers have mentioned, and that may become excessive in a live situation.
Personally, I can live with the hiss, but once again, the incredibly noisy Sovtek tubes only over-emphasize this, so I've gone for Electro-Harmonix AT-7's (and occasionally JJ AU-7's) in the pre-amp stage. Both vastly improve the problem.

Being of 60's (make that Beatles) vintage myself, this comes in useful on occasions. Although The Beatles rarely use much reverb, when it is warranted, this pedal is right-on the mark. I don't use it much with my Casino, but it's terrific for a bit of old surf or guitar instrumental material. (Think The Shadows or The Ventures).

I've been playing for over 40 years, so I'm well settled in what I like, and I certainly DO like this. It's not the "HOLY GRAIL" of reverbs, but it certainly gets close at times! (Maybe the HOLIEST GRAIL is a goer?)

This is a 7 months old EH Holy Grail Reverb unit. I bought it second hand and it has to serve me at home with a small reverbless guitar amp (in fact a Fender Bassman 20 with a guitar loudspeaker). The manual wasn't in the box, I don't need one. It's easy to handle. Most of us will use the included EH adapter: polarity is reversed to most of the Japanese boxes. Though you can use a 1.5V - 12V variable stabilized 1000mA adapter but you'll have to deal with the polarity!

Now I've got some Fender tube amps with reverb and in theze amps no reverb sounds the same!! The Holy Grail Spring Reverb fits right in. It's quite natural sounding if you don't over do it. The Hall effect is ok. The Flerb, you like it or not! Reverb level can be fine tuned easily to what you like to hear. There is only a very slight hiss when the effect is turned on and to my ears there is a small volume drop.

Well as I said it is only 7 months old and it is was well treated by it's former owner. Very clean! But I had some problems keeping it running when I got home. A plop and a massive volume drop!! Besides that the reverb type 3-way slide switch was making some ugly electric noises. The volume drop disappeared when I turned the reverb knob. Allright, dirty switch and potentiometer. When I took it apart I noticed two of the four chassis screws were lame, turn, turn, turn, but didn'go up. I managed to get all four screws out and had a look inside: what I saw didn't make me happy: the circuit board was kind a floating, it was attached very bad, thin wires too. It didn't look road proof at all. I cleaned the switch and the pot, put the thing together and switched on for quite a long time: problems gone. The verdict: The housing is weak and in my opinion not road proof. The electronic component are cheap and is connected with cheap, thin wiring.
Is it allright for me? Yes. I don't go on the road with it and with my electronic know-how I think I can keep it running.

Never dealt with them (their tubes are ok)

I like the clean Fender sound music. This Reverb fits in with that sound. I was looking for a good sounding, not too big, inexpensive reverb unit. I found one. I'll treat it gentle and it will serve me for sure.

It's very easy to use, because there's one knob for reverb level and one switch with three settings for hall reverb, spring reverb, and flerb (flanger & hall reverb together).

It works great in fromt of an amp if you use it by itself with no other effects. The pedal works best in the effects loop of a guitar amp if you use it with distortion, either the amp's distortion or a pedal in front of the amp. The Holy Grail doesn't work well with distorion or other effects when placed in line with them in front of an amp. The best set-up would be a distortion pedal (like a Big Muff) in front of an amp, and all other effects in the loop with the Holy Grail last in line. The reverb is excellent. The hall sounds like an empty warehouse with a concrete floor, and the spring setting sounds almost exactly like the reverb in a '65 Fender Twin. The flerb setting is odd and more of a novelty effect. As far as I'm concerned they could have done without the flerb, and put a plate-style reverb in there instead.

The nickel-plated casing is thin on the top, front, and back of the Holy Grail, and the coated-metal sides and bottom are also thin. The switch inside is a 3PDT type and is very sturdy, but the housing isn't suitable for heavy 'stomping'. It would be best to treat this pedal gently, and if done so it will be reliable enough to last a long time. I give it a 10 because I consider it a 'switch' box housing instead of a 'stomp' box.

Electro-Harmonix are a good company. I have spoke with them on the phone and they're polite and will answer any questions you might have.

For reverb in a pedal, this is really the only choice. It sounds much better than a Boss reverb pedal, and much, much better than a multi-effects unit like the Boss GT-8. If you treat the pedal gently, and use it in the effects loop of your amp (if you plan on using distorion with it), then this is your best choice for reverb. I don't think it sounds "digital" at all, especially compared to other digital reverb pedals or effects. The spring reverb effect alone is worth the price of this pedal, and will get the surf sound with ease. I give it a 9.

Easy to use, I find it best used in the FX loop.

I use it with a Strat and a 5 Watt Palomino tube amp. It makes the lil amp sound like a real tube amp. I use no other effects. The spring and hall settings are great and do what they do: produce reverb. I do not find much tone reduction/loss when using it in the loop. I give it a 9 because there are better sounding reverbs out there but it would cost over a $100 more.

Based on the previous reviews, I purchased the extended 2yr replacement warranty.

This is a great reverb for an amp without one. And for clean tones or a little overdrive this is the best value for stomp box reverbs. I've played for over 35yrs and have owned all kinds of guitar stuff. I tried the Boss, Digitech, Visual Sound, and Danelectro reverbs as well as echos and delays. I tried the Holy Satin, the Holy Grail Plus. All have different sounds and modify the tone of the guitar. I just wanted straight reverb, so I chose the Holy Grail. It has and does everything a straight reverb does, and is compact like my rig.

Very easy to use: Choose your type: Spring, Hall and Flerb... Dial in your amount of reverb you want and away you go.

Using it with a Kustom 100watt amp head through 2x12 celestion speakers (Randall) with my telecaster as well as on my efx loop for my kustom acoustic amp. I use it on voice and guitar. In my opinion it is one of the best reverb sounds that I have heard. I am positive there is better reverb out there but I haven't deep enough pockets to grab that kind of sound.

I have had this for several months and no traumas here. I do get a little cranky with the odd power supply that it requires and it can become a little painful to set up with a very special EH power supply for one pedal. Still wouldn't trade with it.

N/A never had to deal with them

Well first I should say straight up I am an EH junky. I have a massive soft spot for all their pedals, strings and tubes which may prejudice my overall rating. This pedal I use a lot and I love it. If it got lost or stolen I may consider upgrading to the later version such as the holier grail etc

simple one knob-job. i love this feature.

i use it with a n.z built malcom watts plexi-style 100w head and 68 sound-city quad. plus a barber ltd 'drive' pedal. it sounds fantastic , hard rock, blues, indie, jazz, all sound surperb thru this pedal.

no probs, so far owned it two years.

never. all good.

fantastic, simple, reverb-echo-type pedal. its a main part of my tone.

Very easy to use. Large knob and three settings.

On your amps clean channel with no other effects on the pedal does a good job but with other pedals on, overdrive etc it sounds bad.

Here is where it fails. Not just this pedal but a lot of EHX pedals I've owned. These pedals stop working after 6 months to one year of use.

If the pedal is under warranty and you have the receit you can send it to EHX in NYC and they'll fix it. The problem here is you not only pay shipping sending it out but also on the return...

A little too much hype with this pedal...

The good sound is inherent. The three-way switch and an intensity knob. I was able to patch this unit through mt Boogie Road King's effects loop. The spring setting can add to the inadaquate reverb on the boogie and almost make it sound Fenderish.The switch is large and positive, however in this case the King Kontroler does the switching task. The hall mode is more effective. The manual is simple and to the point and I even remembered to fill out the warranty card. Power supply is included a big plus.

I wanted the sound for Johnny A and the electric blues of Mike bloomfield. I almost went out and purchased a Marshall JVM because of the superior reverb. The noise factor is low and through the loop it is almost unnecessary to turn it above 12:00. The third position is reminicent of a chorus/flanger sound with gobs of reverb. When used with the GNX4 one must balance the reverbs or you can go dry on the reverb from the GNX4. Again I use it with a boogie Road King and have tried other reverbs this one is the best.

Not owned long enough.

No reason to contact or interact.

I play rock, trying to learn Jazz and this achieves the level of sound that I was trying to reach. 45years. Tons of stuff from 4 decades. If lost or stolen I would replace it with a higher end Holy Grail. This is the first product I have reviewed that is actually small enough to loose. I love its simplicity and the sound is exactally what I was looking for. I have tried and own other products this is superior. This always embelishes my music. If you need reverb or extera reverb these pedals are the real thing Bluwail wouldn't lie to you! If a rating of eleven exsisted (like on the volume knobs of my amps)it would be my rating.

One knob for level, one three position switch... easy enough, even for a beginner like me.

If you like surf music, from the classic sounds of the Shadows, the Chantays, Dick Dale and the Ventures, to the more contemporary Lost Acapulco, Sr. Bikini and the Surf Coasters, you got it all with this pedal! Great on Spring for classic surf and incredible on Hall for your modern stuff. Man, the Flerb is awesome for experimenting. I got this pedal for the spring but keeping it for the Hall! Clean sound, great tone, even with Entry level amps like the V-tone by Behringer. For just over 100 bucks your 50 dollar amp sounds like a 500 dollar one! Not very friendly with other pedals: I own a Digitech EX-7 and it drops the tone a little bit, but I discovered that if you connect your holy grail at the very last part of the chain (right to the amp and taking the other effects output as input for the holy grail) the brightness loss is minimal... I love it!

No probs so far...

I haven't had any problems with it, but their website is very good at giving info away.

I love surf music, and this thing satisfies me in every bit. Great sound with single coil pickups, great sound with humbucking. Adds brightness to cheap guitars and warmth to good guitars. I own a Gibson LP studio and a no name Stratocaster-ish and man, do I love this pedal!

easy.

it sounds pretty poopie. if you can imagine "cheap '80s digital reverb" you've probably got the picture. it does not interact well with other effects or the front end of an amplifier. it is cool for the occasional texture though. because it sounds cheesy and drowns/washes out the guitar signal, and because it's basically just one seriously long reverb/digital delay tail with a volume knob, I can't say that the sound is "quality. " this thing is an Atari, and not in a cool "vintagey" way........

sure. solid state electronics in metal boxes are very reliable. switch and knob still switch and knob.

I play guitar. Johnny Cash, Bert Jansch, Cake, Spoon & that sort of stuff. been playing two decades. Vox Ac30 top boost & Crate V58. Fender Jazzmaster. Gretsch country gentleman. martin d35.

Dead easy to use. One knob and an on/off switch. The best sound is around the 12 o'clock position. Before that, it's a little too polite and the effect gets lost. After that, it's too much verb for me.

It sounds lovely ....on its own. However:-

- the pedal does not interface nicely with other pedals. There is a tone degradation noticeable particularly when the pedal is on with fuzz or boost (I use BYOC Ultimate Fuzz and a Voodoo Labs Sparkle Drive respectively).

- there is a volume drop when the pedal is on. Since reverb is going to wash your sound out anyway, this is a double whammy. A similar problem with my Boss Tremolo ultimately stopped me from using it in my live set-up.

Not too good. On my pedal, if not everyone's, the sockets are rather poorly made. Some cables need a bit of jiggery-pokery-wiggly-wobbling to get a good contact (particularly in the OUT connection).

The footswitch is also not as positive as I'd like (I've no other EH pedals to compare but the switching on a Boss, a Voodoo Labs or MXR is far better).

Never tried.

Overall, I probably wouldn't recommend this pedal. That said, I don't know what alternative I would recommend as, when I first played it, I thought it was gorgeous. It's only by living with it for several months that its idiosyncracies (interaction with other pedals, volume drop, build quality, etc) become apparent.

easy yeah but for having only one knob and a switch its a little tricky to get the real voice of it for adding the right amount of reverb.

Somewhere around 1:00 - 2:00 theres a spot between where the guitar meets the reverb on the 'hall' setting that I love to tweak with to make the guitar louder than the reverb. the reverb sounds great and has a character that I love about it, I only use the hall setting. Goes well with a clean amp for adding reverb. sometimes there is a gritty sound that seems to sprout when messing with other effects but if you have other effects on then turn this off because it just a shimmer anyway.

ok i bought mine used so i cant really complain here but im really dissapointed about the reverb effect not coming on sometimes when i switch it on, in order to fix this i have to unplugg the battery plug in the back and plugg it back in, very ghetto.

i use a telecaster and fender tube amp with other effects. i like radiohead, interpol, beatles, nirvana.

Reverb is one of my favorite effects, I used to use the reverb on my deville but now I turn it off and use the holy grail for my reverb, I also got a line6 verbzilla which I use as a ambient effect, you can get the holy grail sound out of one of the verbzilla spring settings but not the same character... the holy grail has good reverb! love the splash back tone off the high strings from playing full chords. anyway when I fist tried the pedal it didnt impress me, just sounded like a reverb but after awhile I became truly surprised with the holy grail do to its concentrated sounding reverb.

If you know how to turn one dial, you've mastered this product and will get a great sound immediatly. One knob and one switch..all that anyone could possibly need in a reverb (and more actually) There is a manual but this will be the last one I read when I catch up on reading 20 years worth of manuals..if you know what I mean. It's not needed.

I'm looking for blues sounds, electric blues that came out of Chicago and Detroit, and those sounds came mostly out of Fender amps (by the 60's anyway). The reverb was the only effect available in that setting (occasionally some Vibrato) and it was enough. THIS PRODUCT DELIVERS THAT SOUND. Perfectly to my ears.

I bought it for the spring, but I'll be keeping it for the hall. You can play blues, but you can also use this as a component in any crazy thing you want to do that may need reverb. Plays nicely with others, just put it last in the signal chain.

I use a modded Mexican Tele (has 1 p-90) through a 80's version of a Princeton (a humble put trusty servant). Occasionally I dabble in wah. Not noisy unless you've messed up your AC power. Mines clean and I hear nary a hum. Beautiful.

I bought this one used and it had seen some miles, but it's been running like a champ for some time now. I happen to like the science-project-gone-mad quality of the Electro Harmonix boxes. I suppose they're not as sturdy (or heavy) as something cast. Oh well, I like it. I haven't had it long enought for a perfect mark, but I score this one high.

Electro Harmonix is not known for making themselves available easily. In fact a sent them an email about another issue, not related to this box, and I'm still waiting for a reply.

Hopefully the quality and simplicity of the design will mean that I can rate this low, and still not be too worried.

I've been playing for 20+ years and appreciate when a product nails a sound I want without getting to marketing-clever-cute. This purchase comes through for me. I have a Lexicon PCM60, an Alex, and loads of Alesis boxes, a Furman spring reverb, so I knew the sound I was looking for, and was very pleased that EH delivered up an honestly designed box for people with simple needs, like me

Simple 3 postion selector for Spring/Hall/Flerb. One knob depth adjustment.
I had it setup with good results in 5-10 minutes out of the box.
One page manual, quicker to just plug in, play with the switch, depth knob.

I bought this to try for passable spring reverb in place of the weak verb in my Boogie MK IIB head. It's last in line in my pedalboard before hits the amp input. I plan to try it in my amps effects loop to see how it sounds this way.
Used it on a gig last night, no noise problems at all. I find it quieter than the spring reverb in the Boogie and a Rivera Chubster that I use.
While it certainly isn't as realistic as the verb in several old bf Fender amps or even an Ampeg Reverberocket I've owned, it does a decent job for a digital pedal. Plus, you can really drench your sound in reverb or just get a pinch if that's what you want.
Passes the "Pipeline" test comapred to Boss, Digitech, and other digital reverbs I've tried.
I've not been impressed with the Fender re-issue tube reverb units. Can't get enough verb out of them when you want that drenched sound.
Sure, there's some nice alternatives out there if your willing to pay the bucks for an outboard boutique reverb. But when you're on stage competing with drums, bass,keys, horns, the best reverb gets kind of washed out anyway.

No problems yet, only used it once to date.

No experience dealing with EH.

I play Blues, Jazz, Ambient, but most live application is with a function band.
Have 40 years playing experience- old dude! I gig with Mesa Boogie MK IIB(1983) and newer Rivera Chubster amps with dot re-issue Gibson 335. Other pedals: Keeley Compressor (2 knob,) Fulltone 10th Anniversary FD2 Mosfet, Barber DD & Small Fry, Fulltone ChoralFlange,
Boss DD5.
Bottom line- I've read lots of reviews on the EH Holy Grail that almost persuaded me not to buy it. With GC's return guarantee policy I figured it was a safe bet. So far I'm very impressed with this pedal and would recommend to anyone looking for decent, reasonably priced reverb. For the extra money (about $150 more) the only other verb I've tried that's worth the price is the all analog Vanamps Reverb Solomate.

Easy, Switch with three settings and one knob.

I dont know what people talk about. I use this with my Peavey Valveking in the FX loop, its always on. I hear substancial noise in my amps reverb, but this one is pretty quiet. Its a great pedal i keep it at 1 o'clock. But on spring all the way up its great for volume swells. I think its a rad pedal that sits happily on my backline.

Ive heard that this breaks with constant stepping but its always on so well see.

Never dealt with them.

Cool simple pedal that has good sound.

You know the drill--one knob and one slider switch. They don't make pedals any easier to use.

beautiful, lush sounding reverb. both the spring and hall settings are VERY nice sounding and are definitely usable. the flurb is a definitely "effect" and not something i would use very much.

the problem, as has been noted many times in other reviews, is the noise. turn on the pedal and you get a very loud WOOOOOSH sound. i suppose that this noisefloor would be "acceptable" in a live gig setting where the "WOOOOOSH" would be covered up by drums, etc. But for practice and recording, it's totally unusable.

Unfortuantely, i bought it for recording......so it's going back.

I don't know. It's going back.

I've opened it up and there's not much in it......the case looks pretty cheaply made and the switch and jacks are cheap and not very well supported/reinforced, so i'm not sure it'd be up for the long haul.

Certainly it's not as "rugged" as a Boss pedal, which has always been my litmus for that sort of thing.

Never dealt with them.

Overall this pedal gets a 3. The reverb sounds great, but the noise makes it totally unusable for recording and practice (which is why i bought it).

great sound, as ehx says 'dick dale in a box'. i really like this pedal because its really simple and it has a very realistic reverb sound. one knob, three different modes(spring,hall,flerb. got the manual, sticker and everything. the manual says that the pedal is not to be used with any other adapters other than the ehx holy grail stock adapter, they say that something might break and the pedal wont work.

very, very realistic reverb. sound quality is qood, no hum when engaged. the spring setting can be anoying when the reverb knob is up all the way because there is a slight volume drop, and when the knob is up all the way on the hall setting, theres just too much reverb. the best is to set the knob at 12 or 1 oclock, thats when the reverb kicks in with no volume drop and such. the flerb setting is really cool, i use it a lot, especially with feedback, but you cant really hear it until its up to 3/4 of the knob or the whole way. what bothers me is that theres no reverse reverb function on it. i only had 90 euros, and i could either buy the digitech digiverb or this and i chose this because it wasnt too digital as the digiverb. i dont really mind not having the reverse reverb function, i'll get a special pedal for that in time... im using it through a Fender CIJ '06 Jazzmaster and a roland cube 15 amp, yeah i really have to switch this amp. maybe for an epiphone valve jr combo. i also use 4 other pedals, a big muff, a ds1(bad), a mxr blue box and a crybaby wah wah pedal. overall the sound of the holy grail is awesome through these.

yeah, i dont gig but i can depend on it, it's built like a tank.

never dealt with them....

i keep an open mind on music and i play noise/alternative,blues,surf and some funk. its perfect for all those, with my other pedals turned on it creates ear piecing feedback. i've been playing for 2 years. as i said my setup it Amp-Holy Grail-Big Muff-DS1-Blue Box-Crybaby-Fender Jazzmaster. i didnt compare it to any other reverb pedals, i thought of some different ones but i like this one the best (except the holier and holiest grails) i wanted to buy a phaser or a tremolo pedal, but i got this one since its most fun. as i said, i wish it would have a reverse reverb function. helps me with my sound, creates great feedback and echoes... i love ehx pedals, they are really good for the price and sound mind blowing.

It's as easy as it gets.... turn the knob for more......reverse the knob for less, as with all Electro-Harmonix effects it's a Musicians wet dream! Easy!

Spring Reverb in my opinion is the most overrated effect ever, I use vintage tweed amps that sound kick ass WITHOUT reverb, so when I add reverb I want it to be outboard, not permanently in my signal path 'messin with my tweed tone. This reverb is HANDS DOWN the best outboard, quick set up, add it when you need it reverb and I thank Electro-Harmonix profusely for making this sucker. Sounds magnificent! Flerb is so cool I can't imagine doing some of my tunes without it!

Two years of HEAVY use and no probs, but you have to use it's power supply, non electro-harmonix power supplys add noise. This is something that a lot of pedalboard users don't get because they try to use it with their pedalboards power supply. Does not not work, you have to use the power supply that comes with the pedal.

never had to use 'em.......

Unbelievable value! Spring reverb purists.....blah blah, yada, yada! I have sold so many so called "sought after" BLACK FACE FENDER REVERB amps over the years (at a large profit I might add) because of the lame signal path that spring reverb adds to an amp, only to retire to my studio to crank my tweed deluxe and occasionally add what I consider the best sounding reverb ever.... I don't want Holier, Holiest, Everso Holy! I want EASY, SOUNDS GREAT!

Very easy to use. it only has an on/off switch, a selection switch with 3 reverb choices and a mix knob. you can get dialed in very quickly.

The claim of this box is, and I quote from EH:

"The Holy Grail will make you a believer with its emulation of classic Spring reverb so faithful that even Dick Dale couldn't tell the difference"

Well, I own a spring tube reverb tank like Dick Dale and there is a big difference. I think The Holy Grail has a dark sound and the reverb tail is way too long. Since it does not have dwell and tone control you cannot adjust it. I can emulate the sound of the HG on my tube reverb unit by turning the dwell way up and the tone way down. That tone and dwell setting is fine for some things but not everything, but then again what can you expect for $89.99. But for the price I paid, it sounds fine. I have it on my pedal board and use it for one night stands, when I don't feel like bringing the tube reverb. I get used to it a few songs into the night

If you are looking for the true tube spring reverb sound, this is not it. If you are looking for an economical solution to a lack of reverb in your amp, this is fine. The question then should be: Is it worth the money? Yes, Its worth 89.99. The best thing about the newer units is that they are true bypass, so when it is off it does not color your sound at all. so when I use my tube reverb I don't have to unplug it from the pedal board.

I have only used it about a dozen gigs so far and it has never given me a problem

Have not had the pleasure

I play many different styles of music including surf music, Jazz, Rock, Pop, etc. I play an old strat through a custom made, point to point hand wired, Tweed Double Deluxe from SDG Vintage amps. He also made my tube reverb unit that is a replica of the old Fender.

No I would not buy another if this were lost or stolen. I would try something else

I'll give this a rating of 8 because it is so cheap. If I would have paid retail list price, $138.00, I would have rated it lower cause it is not worth that much

Does your guitar and amp sound good to begin with? If not this will not fix your shitty sound. If your guitar and amp sound good, this will make it sound much better. Unless you can afford an all tube vintage reverb unit for $1K+, you cannot complain about a $100 unit that sounds this great. If you still must, then buy a good combo with a high quality reverb and shut up, and realize it's limited too.... If you are running 5 gain stages, and need a good noise gate, then buy one...but don't blame the reverb for screwing up your sound. You probably had problems to begin with.

Sounds great on Spring, Hall, & Flerb. Spring is very warm and Fender like to mild slapback, Hall can go from subtle to a nice mild echo, and flerb is great for higher gain VH style or blues leads. You can get a subtle effect, a deeper effect, or lose your dry signal all together and warp it out. The Flerb sounds great in a mix, but not as well on it's own. Try it with several other instruments jamming though, and it can pick you up out of the mix quite well. Note that the drop in gain after 12 O'Clock is because you are only getting your sound with the reverb, and minus the dry signal. Those of you that don't like this unit, or complain because of that need to learn how to read a manual. Get a clue, don't blame your equipment for your ignorance.

Absolutely no problems. Now if you like to change effects with them powered on, or use bad power sources, or your amp and guitar hums normally, or you unplug your guitar while it's plugged into this, you probably damaged it yourself. This unit well will add effects to your trashy noise as well as good sounds. My amp and guitar are quiet, shielded, and sound good, and so does this. I have been using this for several months, and have had ZERO problems.

No problems, not an issue. Sounds like lots of folks have noise problems they like to blame on effects, rather than look at their buzzy amps, low quality cords, and unshielded guitars. Check out Tone Quest's review of this unit for the low down...

I play blues, jazz, fusion, funk, rock, punk, rockabilly, etc. This is a great all around reverb to use with both tube and solid state amplifiers that lack a reverb. Will it sound as good as a vintage Fender unit, probably not, but will a vintage Fender unit give you Hall and Flerb too for $100 or less? I have several low wattage tube amplifiers, and solid state units that lack a reverb. This is a great, cheap solution. If you make a living as a musician, well then maybe you need more than this, but for an amateur weekend jam player it is great. It doesn't sound digital either...unless you really push it...and it still sounds good to me then.

simple: one knob and one switch (spring, hall, flerb)

the sound is great.
my main reason for writing this review is to comment on the flerb. everyone seems to not think much of it, but i LOVE IT!
the spring and hall effects are great, but the flerb setting gives a cool slow flange to the spring reverb sound.
I use it a ton and nave even recorded with it and it sounds great!
it can adda really cool dimension...

usually mine works well.
every once and a while, it will hum loudly for no good reason, but then the next day sound normal again.
a few weeks ago it just stopped working. i messed around with it, and even took it apart to look for a loose joint. i didn't see anything wrong, and put it back together planning on buying a new one...but then it worked. and it has worked perfectly since...

never dealt with them..

nice pedal.
simple and fairly versatile for a straightforward reverb pedal.
i like it.


yes i'd buy another one. i'd thought about a holier or holiest grail, but i really love the simplicity of this one.

Just one knob and one switch. Pretty easy to get a good sound out of this box

The quality of effect itself is very good considering the price.
Spring and Hall I find very usable, Flurb is fun but not more than that. I used in front of a handbuild Tweed Twin and at first I found what I was looking for. But after a while......

....the problems started! Due to very poor quality of crucial parts the pedal started to hiss and sqirl. I found this problem in a lot of reviews on HS and people state that the pedal is very noisy. A little nuance on that: from the moment it starts to make noise, an op-amp has broken down, so in fact, your pedal has broken down and should be returned to the shop on a warranty basis.

Had two Holy Grails returned to shop I bought them from. On both occasions they were 'repaired' and after a while failed on me again. It doesn't really matter what kind of music one plays if your gear is not reliable. Whatever you play, it will always sound crap. It's a shame Electro Harmonics isn't prepaired to spend, say about, 5 dollars more on this one in order to make it more reliable. Bloody shame

Pretty easy to use, 1 knob, nice and simple.

I play a G&L ASAT Classic through a fender tweed clone. This thing is noisy as all hell. I would never even think of recording with it. The Spring reverb is weak, but the hall sounds cool. Thats what I use most of the time. The Flerb is a novelty, a kinda fun novelty, but a novelty none the less. Oh, and when you click this thing on it takes a little bit away from your tone. Not very much, but enough to aggravate me.

It works when it wants to work... Really have to baby it.

Maybe i'm just so hard on this thing cuz the I'm comparing it to the reverb on my Fender Deville, but overall I was not very pleased with this product. It's noisy, it's unrealible, and it eats my tone!!! RAWR!!!!! Maybe I will save up for a reverb unit...

Very simple: Switch to choose among 3 reverb setting, and 1 knob to adjust the volume/intensity of the effect.

Well, the reverbs actually sound very cool... MAJOR problem is the amount of noise and hiss from the pedal!! I tried it both at the end of my effects chain and in the fx loop - still noisy as hell. In fact, the noisiest pedal I ever owned. It's a shame.

It's an EHX... aluminum box looks nice, but easily scratched and dented.

Never tried to contact them.

I really wanted to like this pedal... but for me, it was unusable because it's too damn noisy. I gave up and returned it to the store.

The only downside is the no-standard power socket - but it's easy to swap out.

Hall and spring are just right for me. Flerb is fun but I'll never use it. Sound is OK - it doesn't suck tone. Problem is that it's just started hissing. It's been OK for 5 months but now the hiss is annoying. I play into a THD Bi-Valve. If I plug it straight into the amp then it's v. hissy. If I put it in the amp's effect loop then it's a lot less hissy - but still a bit annoying. I'll try returning it to the vendor. If it weren't for the hissing it would score 9

See above.

I won't buy another.

When you know what you want from a reverb ??
Very easy.
Set it at Hall, 9 - 10 o clock !!
Ready for anything !!

I have it since 5 years and it worked sometimes good and sometimes bad.
Sometimes it just dont want work, so I must put the adapter ( you need 500 mA. + 3,5 pin ) out and back again, sometimes I must repeat this 3 - 5 times, till it works. But than you can switch it on and off without any problem. Because my Plexi Amp has no reverb, I have buy that. Thinking that it give my some more "magic" because its called "holie grail", ( You know that "glory" Storys ). But at times I notice thats its not, I hold it the 5 years because, its better as nothing ;-) And a reverb is not the "importantsd" gear I need.
I have buy the new Engl souveraign 2x12 combo, with two seperate reverbs, so I dont need this anylonger.
I play since 20 years and have noticed that the best sound is coming from a good guitar, a goood amp ( with 2 channels + seperate reverbs ) and maybe a good Overdrive as Booster ( I use a maxon Ts9 ). And thats it, the more stombboxes you use, the more the main "natural" sound goes away. Also ( extrem ) with the Holie Grail.
I only used it at Hall, 9 - 10 O clock, sometimes, because the rest is f*** s****. What you eccept under a " Flurb" ?! You know !
I dont can say that its a tip, if you need a reverb ! Try something other out !!

Whats is wrong with EHX ??
It looks good but is build from cheap thin alu plates !
Turn in the guitar/amp cables, in and out can damege the box.
Stombing youre feet a littel bit to heavy on the on/off switch can destroy the cover !! Look inside the box and you understand why russian people drink wodka !! The paint job and the end manufacturing is made in the USA but the parts are made in UDSSR !

I dont speak russian and I dont know enough english "bad" words to contact them and say what I thing about them !
"WE ONLY HAVE THE DOLLAR SIGNS IN OUR EYES"

NO, NO, NO
I have spirit and magic in my soul and fingers.
I use Gibsons, Music Mans and Fenders.
I use Roccaforte and Engl Amps.
I play 50 - 100 gigs a year. Cover Stuff or own Music.
I play in studios.
I play since 20 years.
I had testet nearly anything that is popular in the guitar scene.
No, no, no.
This unit is s**** !!

Simple, and straightforward... Simple to get "GOOD SOUND"???

Sounds great till you turn your amp past "1". Then the noise takes over...

It is built cheap but I'm easy on stuff so it would probably last forever...

Didn't bother...

Holy Grail not so Holy...

--------------------------------------------------------------------------------

I bought one about a week ago (Holy Grail) at Guitar Center. I think the spring-reverb effect is pretty impressive. The other settings don't interest me. This would be a really cool piece of equipment but...

It produces a lot of hiss in my old amps (Stock BFPR/New Build 5E5A Pro clone). No, really, a LOT of hiss!!! (Think LOUDER than driving on the freeway with your windows down). There is a bit of squeal, or high pitched whine, that is pretty annoying too. It would be even more noticable but it is somewhat drowned out by the hiss. The switch makes a loud POP when you step on it. The box itself is microphonic, tap on it and you will hear it in the amp. Yes, I tried it with more than one amp, more than one guitar, wall wart plugged in to a separate circuit, different cables, even different tubes...

I read reviews here that some are better than others so I returned mine to GC and got another. EXACTLY THE SAME ISSUES! This one will go back too. UN-USEABLE...

Reading the reviews for the Holi-er Grail there doesn't seem to be the same problem with noise. I'm curious if it has the same spring-reverb effect, the one part about this pedal I like (I'd appreciate some feedback about this pedal). I don't need/want all the extra doo-dads but if that is what a guy has to do to escape the noise...

It's a joke. It also sucks that you have to use the power adapter that comes with it unless you have the newer Pedal Power.

This is an awesome, practical delay. And I emphasize practical. The guy below compares it to a Fender reverb unit. Obviously, the Fender dominates. But what practical, touring musician, would bring along his/her priceless, vintage Fender outboard reverb unit? I sure wouldn't. The Holy Grail is an awesome, simple reverb. The verbzilla and digiverb are cool, but if you want simplicity at it's best, go with the Holy Grail. Great sound and can do a pretty cool gated reverb a la Kevin Shields. My personal favorite is the Spring setting. I read about people having horrible noise issues. I A/B'd mine and didn't notice any noise problems.

I have mixed feelings about ehx boxes. I don't trust them, but nothing's happened to me and I've had mine for a 4 months. I'll probably rehouse the Holy Grail. I've heard people blowing out their Holy Grail because they use an insufficient power supply other than the one that comes with it.

Never dealt with them.

This is a very practical pedal. I recommend finding it used because I don't think it's a 100 dollar pedal. I traded a Boss RV-3 for this and I have noticed a greater improvement in my tonality. Definitely check it out and see if it suits you.

Using this is obvious, there's so few controls.

I won't bore you with a list of gear, other than to say I'm comparing this with a Fender 1963reissue stand-alone valve spring reverb, modded slightly to take it as close as possible to the original spec (6L6 not 6V6 valve, JAN NOS 12AX7s etc).

I was attracted by the advertising, which implies this pedal can make the same sounds as a Fender reverb, and because it looks less fragile than the Fender. I did wonder why the EHX website's sound samples don't include any surf guitar. Now I know. Dick Dale may or may not be able to tell the difference but I bloody well can. The Holy Grail is no substitute for the Fender unit. The Fender has pots that control dwell (basically the overall delay time/how hard the srings get twanged), mix (clean and fx signal) and tone (treble roll-off on the reverb signal only). These three controls interact in a very complex way, giving everything from a fearsome BOING with almost no reverb tails to swimming-with-head-under-water reverb wash. The tone control is very important in this as it has a huge impact on the reverb character, and the Holy Grail has no way of adjusting anything other than "level".

And if you kick it it doesn't go CRASHH-HH-HH-H-H-H-H either.

On the plus side it's a good copy of the single-control reverbs fitted into Fender amps, and when my hyper-active sax player trips over it it doesn't go CRASHH-HH-HH-H-H-H-H.

One thing to watch - all these reverbs that go before the amp sound best if the amp is set (relatively) clean. Ultra-long, compressed and distorted reverb tails are not pleasant (or even interesting).

I didn't notice whether the Holy Grail butchers your tone when its (supposedly) by-passed or not. My (limited) experience of EH stuff is that it probably does.

No idea about reliability. My EH fx are both from the 1970s and I've owned them both from new. Apart from having to redo/repair lousy soldering on most of the joints (dry joints, joints with mountains of solder, wires attached to the board/sockets by a couple of hairs) all I can say is that they keep working.

Would I buy one if it got stolen? I didn't buy the one I was trying out.

One Knop and a 3 styles switch its enough for a reveb, isnt it ?
Maybe a seperate Volumen...but no.

I have it on Hall and set the effekt at maximum 11 o clock,
this creates a reverb I can use everytime ( Its always on ).
Clean, chrunch, fat distortion...it gives my sound a good deepth and
warm note from the beginning.
Spring is not good enough and flerb its to psycedelic... unusuable, for me.
The more you have the big Knop turn clockwise the more bottom
looses your sound. So 12 is extrem church like.

My live Set up : Gibson Paula, Fender 66 Strat, ESP M II - Holy Grail - Digidelay - Fulltone 69 - Jekyll & Hyde red - Crybaby 353 - in a Marshall 1959 Plexi - 4 x 12 Vintage 30 or Mesa Lonestar 2 x12 Combo.

The way I set it, its maybe simple but it works.

Have it for 3 years always on my Board an sometimes the effect is not ther. so I must put the Adapter off and than put it back again.
BIG BULLSHIT .
but I can Live with that.

YOU NEED A 3,5 PIN CONVERTER. That is not the normal Visual Sound BOOS, Ibaneze switches !!!!

An It has 500 mA Thats very much,

?

A reverb is a must have for any Guitar player
This one is good, simple, sounding and its cheap !!
For me it works well .

This device couldn't be simpler to use. I even manage to tweak it with my toe.

What can I say? It's changed my life.. I use it with EVERYTHING- Electric and acoustic guitars, all manner of keyboards including a Mellotron and a Vox Continental- and it never fails to be transformative in some way. The hall setting is so realistic that I expected to hear the sound of the janitor kicking his mop-bucket over. I could happily have one built in to each of my keyboards. My amps are all reverbless Selmers and this thing is a GODSEND.
BUT... it's obviously not true bypass because you can still hear the sound of frying fish in the background if it's turned up yet switched out. That's a bit of a shame. I shouldn't have to change switches when they must cost sod-all to EH in the first place.
Still, it's quite inexpensive considering just how brilliant it is. You really must hear a Mellotron 8-voice choir through this- it's utterly fantastic. The 'Flerb' setting can be wonderful with combo organs too. It would be a 10 were it not for the noise when supposedly bypassed, otherwise thanks EH. I'll have your babies.

I have to depend on it. Occasionally it's refused to 'start' unless the AC adaptor is plugged into the Grail before the mains. I looked inside it once and just saw an enormous IC.
I'm quite a techie but if this died I think I'd be better off throwing it over the hedge than attempting to repair it.
Of course I'll use it without a backup. Life's too short!

Question. Why did the paint start falling off within days? It looked SOOO pretty for the first week...

Never had to.

I love this thing. As previously stated, I'm sure that I would tape one to every instrument I own. I play allsorts from batty electronica to prog-rock via light music and folky stuff.
It just sounds ACE with everything. I'd cry if somebody nicked it. Shame about the bypass but I suppose I'll just have to bodge it myself. Let's hope it survives! I don't really trust anything that depends on one huge IC to last long when it gets trodden on repeatedly..
Anyway, it's a jewel.

pretty easy - more or less one knob. But you have to be carefull with it's position. So watch out...;)

I like it turned pretty much all the way up in the hall mode. It`s a slightly distored endless reverb, bit shoegazish, bit velvet undergroundish. Really nice, and far away from the sterile clean boss reverbs.
I only use it for certain parts of songs.
I do not use the spring mode because I think it's rather boring and not really usefull for the music I play. Mabey for blues it`s fine.
Same with the flerb mode wich I find pretty stupid.
Unfortunatly it`s a noisy hissing bastard. But just turn it off while your not playing, that`s what the footswitch is for.

my setting:
epihone firebird-tu2-fulldrive2-ts808-holy grail-double muff-OCD-supa trem-dd20 delay-fender stage lead.

We all know that electro-harmonix pedals do not last long. I do not know why they`re sill built that way. They don`t seem to learn. Nice sound, but not reliable. Be carefull with it!

no idea

I play indie pop-rock.
The holy grail is pretty much the best reverb I know, if you want a dirty reverb.
But be sure that this is what you want. Otherwise, go for a boring boss, or even better: play without reverb!

3 settings and a level control. Doesn't get much easier than this.
Instant satisfaction.

I couldn't be happier. I LOVE it.
As I have a Fender Bassman (without internal reverb) I was looking for a simple stompbox that could give me some nice ambience.
Incredibly hard to believe that this is digital... It sounds SO warm and convincing! Makes you want to rattle the box to check if there's springs inside :-)
It has 3 different modes:
- SPRING: mimics an accutronics spring reverb, as found in most combo amps. very realistic. sounds best if used in small doses.
- HALL: sounds like you're playing in a cathedral. my favourite. I set it at about 2 o'clock, perfect for droning shoegazer-stuff or spooky jazz.
- FLERB: reverb with a touch of flanger on the decays. not very useful for me, but a cool feature anyhow.
The level control actually reacts as a "wet" control, so if you crank it, the overall volume of your sound will be lowered a bit. That's the only drawback of this pedal really. But I don't mind, because lately I tend to leave it on most of the time.
Make sure you buy the new version, as it has true bypass!

So far so good. But better watch out with EHX pedals... they're not the most sturdy. And that's already an understatement.

A little remark: when I used it the first few times it made a loud pop when I engaged the switch. Very annoying, because this makes it virtually useless for live or recording applications.
BUT! After some days the pop started to get gradually quieter and quieter. Now we're about a month further on, and the pop has disappeared *COMPLETELY*!!
So: once the footswitch has 'worn in' there's no more popping problem.

I play a lot of different stuff... mostly indierock (Pixies, The Smiths, Echo & The Bunnymen, Fischer-Z, The Sound), 70s/80s postpunk (Gang Of Four, The Chameleons, Joy Division), new wave (The Cure, Cocteau Twins, The Sisters Of Mercy), classic rock, bluesy licks,...
I mostly use this pedal in combination with my Fender USA Telecaster, a T-Rex Alberta overdrive, Boss SD2 dual overdrive, Boss CH1 chorus, Boss BF2 flanger (the early 80s japanese one), Ibanez DE7 delay/echo and my beloved Fender '59 Bassman Ltd Reissue.
It sounds fantastic. While other pedals may have more possibilities (eg. the Boss RV-series) the Holy Grail simply SOUNDS much better. Warmer, more organic, more natural. I'll say it again: when you hear this, you'll have a hard time believing this pedal is actually digital. It sounds THAT convincing.
Imho, it even sounds better than some "real" reverbtanks I have heard in certain amps.
Hell, this box even LOOKS cool!!!

This pedal is very simple, 3 settings and a knob to ajust the intensity. Didn't take me long to get it sounding good.

My Set-up: Fender American Deluxe Telecaster through a late '70s Hiwatt DR-504

There are two MAJOR problems with the sound of this pedal. For one, when turned off, it changes the tone of the guitar. And secondly, when turned on this pedal makes a buzzing sound in the background...

... two things which somehow I don't recall hearing when i tested it out at the store, I feel real dumb.

I've only had it for two days, and I allready want to get rid of it, so I can't really say anything on this. However, upond doing further research I have noticed that many people have complained about the reliability of this unit.

If you care about tone, DON'T BUY THIS.

Easy to use. Can't be much easier, but don't buy this pedal. Read further.

I like the sound and the options. Spring, Hall and Flerb - really cool. I use Gibson guitars and a Matchless amp. Not Noisy at all - sounds true. Don't buy this pedal.

HOLY CRAP - the thing is terrible. Don't buy it - I've had it for just over a month and it totally crapped out. The reverb knob became a volume knob - it fades out my guitar signal. What's up with that? 35 days is how long I've had it!!!!!! Total crap.

We'll see, I've written them about it, but we'll see... If they fix this situation, I'll update you guys. But, really, beware.

It's a switch and a knob. If you can breathe, you can handle it.

I prefer the 'flerb' function on this pedal because it produces a nice chorus/vibrato mix into the reverb. The spring reverb is decent but at extreme settings it gets harsh and metallic. Same goes for the 'hall' setting.

This pedal worked for 8 months and then mysteriously, the knob acted like a volume, instead of an effect knob. When turned clockwise, it simply turned down the volume of the signal and there was no reverb effect, whatsoever. I sent it for repair and they obliged curteously, but the pedal worked for only another 3 months before the same problem occurred. At this point I stomped this pedal into a concave worthless can.

See above.

I've owned lots of pedals from various manufacturers over the last 20 years of playing and this is the first time I've had such an experience- and not the Jimi Hendrix Experience. It's too bad, because overall it is a useful item, and I loved the flerb setting.

If you can't figure this thing out, just kill yourself now.

I'm playing more drums than guitar now so some sacrifices have been made and my rig is really simple (hardly a rig at all) - a Gibson Special SG or Fender Standard Strat into a Dunlop CryBaby and this thing, out through a Sovtek Mig 60/Vox AD412. I used to have a Crate combo with digital effects and I always thought reverb was a decent atmospheric effect. Clearly I knew nothing because this pedal adds another dimension to whatever you're playing. Oh, and "flerb" blows my mind, maaaan.

I'd say it's built like a friggin' tank.

No idea.

It's not a bad thing to have. If you can afford it, get it. If you can't, start saving.

I wish all pedals were like this - one switch, one knob. That is so cool.

The spring reverb that this thing produces is almost too good to believe -- far better than Boss and Digitech, which sound sterile and digital by comparison. However, these pedals are NOISY, or at least the 2 that I owned were. Both produced a very noticeable hiss which seemed to increase over the course of a playing session (using the correct EH power supply, and high quality Monster cables). What a disappointment, because again, the reverb is really stunning, save for the noise. This maybe a random defect, since some users report no problems, and I almost bought a 3rd unit hoping to get lucky. Ultimately, I opted for a Line 6 Verbzilla (very nice; very quiet).

I played mine regularly for over a year without any "other" problems, before finally getting fed up with the noise. The insides evidence quality components and good workmanship. However, the fact that so many reviewers describe the same problem as me, while others report no issues at all, suggests a serious lack of quality control.

Been playing classic rock and blues on and off since 1972. Too many amps and guitars to list. If you're lucky enough to have a relatively "quiet" HG, hang onto it, because there's no better sounding reverb pedal out there. If EH would whip the noise issue, this would be one of the coolest pedals ever! However, given my experience, I would not buy it again, or recommend it to others.

Piece of p**ss. Just one knob to dial in the amount of reverb, spring, hall and "flurb" plus footswitch.
Second hand but unused (its immaculate and came with all the original box candy :-) ) bought via Ebay.

Too much gear to list again.. see my MXR Dynacomp review for my list of gear.
I've replaced my Boss RV-5 with this little sucker and the difference in reverb quality is astounding. This blows the boss away. BY comparison the Boss is fizzy and thin. An awful tinny sound I could never get on with. The Holy grail just sounds so flippin good. You can cut out ALL of the dry signal if you like - you can't do THAT on the BOss and the GRail sounds warma nd very deep. Lovely and authentic. And at the price it is an absolute steal. I was a bit sceptical, but the EHX Holy Grail is brilliant.

Hiss? What hiss? I use an extensive array of quality pedals linked with quality leads into a quality amp fed by quality guitars. No hiss... Maybe I struck lucky and got a specially good one??

Only just had it...
