Marshall JH-1 Jackhammer

It's realy ease.

On my super amp it sounds perfect.

Yeah...

So so...

For Metal its oki.

The Jackhammer isn???t that difficult to use. After a couple of minutes I pretty much got a sound I was happy with (Upgraded by Von Lehmann).

I have my Jackhammer plugged into a clean Blackheart amp and it sounds great. My Jackhammer was recently upgraded by Von Lehmann. I found the original sound of the Jackhammer was not really that great. You could get a good sound out of the O/D mode but the distortion was a bit to messy and I notice a bit of noise (it could also been my home power supply). After the upgrade I found that I could get a really good sound very quickly on both modes. The noise improved a lot and it is much better to play. I can play songs from bands like AC/DC, Linkin Park, King of Leon, The Killers, Bloc Party to the slow and clean distortion of Coldplay. I have found that with this upgrade I can also get a good metal distortion.

It is very reliable never had a problem with it. Works like a charm.

I bought it straight from the shop but later I got it upgraded by Von Lehmann and found them easy to talk to and deal with.

After the modification:
I play a lot of Alternative Rock and don???t mine a bit of metal and I find that it is a great match for me and if you are planing to buy or have a Jackhammer I truly recommend it to be modified by Von Lehmann because it was really worth it.

Is rather 'knob twiddley' at first but with time you get used too it and can change tones completely with relative ease. Contour/frequency may be a bit overkill when you have these built into your amp anyway but be patient and it can be a nice touch.

I run this with either a hot rod deville 2x12 and my Gretsch Corvette G-Love signature guitar or thru a Vox AVD-T 100 head and 4x10 Marshall cab with a Fender FMT or Burns Brian May 'red special'.

Have too say...agree with previous comments on the Distortion sound. Find it very murky and sloppy almost. OD sound though is wonderful. I play everything from Bloc Party/Muse/Pearl Jam through too Thin Lizzy/RATM/Pink Floyd and find the Od setting enough for most of these. Have tried/had Ibanez tubescreamer,Boss Od/Ds pedals before and didnt like them at all.

I run my amps VERY clean and with odd settings...Bass@12,Mid@2,treble@2 with a fair amount of compression which really tightens up the sound but do realise that most people will use a classic Rock 'scoop' eq in general.

This is my second time owning this pedal...but only 'cause my first one was stolen!! I gig about 150/200 nights a year and never had a problem with the reliability of this pedal. I t has taken serious abuse...from drink being spilled in it too a cab falling on it and still the thing gave me the finger and kept going!!

Should always have backup though..mine being another Jackhammer!!

Only dealt with Marshall once and took an age so i cant give them good marks i'm afraid but issue was sorted in the end.

Because of it's Jekyll and Hyde persona between OD/Dist i would suggest haveing a definate idea of what your looking for when trying this pedal out. It wont suit everybody but those who do like it will love it. It isnt a good pedal for Metal,Thrash,Death Metal in my opinion but classic rock and alt rock it's perfect.

In the end...it's pretty cheap and punches above it's weight but only if you use it as an OD pedal and stay clear of the Distortion.

Not so difficult to use, it has on O/D switch, gain, bass, treble, contour and freq. Needs a little time to figure it out, but when you figure it, it's easy.

I'm using it with Cort X-11 into a Peavey Renown 400. I heard about JH-1 and it interested me because I heard it wasn't like a regular dist pedals, and when I tried it amazed me. I wasn't expecting that kind of sound from Marshall pedals... Before I bought it, I was using a Gibson Epiphone S-310, and tried it with that guitar. It sounded really great.

Only objection that i have is that it needs a little more treble.

I like to experiment with sounds, and I really like this configuration. I don't think I will trade this pedal for another for a long time...

I've bought it about a year ago, and it fell from a height of 50cm, and it's like a rock. A scratch was left on it. It's the most reliable pedal I have for now, it's made all from metal.

They only introduced me with the pedal and their opinion was helpful to some limits.

I play Rock, Hard Rock, Metal, and it's almost a perfect match. It's a universal pedal, I even play blues with it. I've been playing it for a year. I have digital delay, wah-wah and a chorus pedal and I combine it. I sounds very, very good. If I would lost it or had stolen, I would definitely buy another one.

Very easy, 2 modes Overdrive and Distortion, Gain, bass midd and treble very self explanatory

I???ve tried and played with many different distortion pedals... but the Marshall jackhammer is by far the WORST!, probably the worst distortion I???ve heard in my life! no real tone, just a loud fuzzy mess!, the only part of this entire pedal I would say anything positive about is its overdrive, it does provide you with a fairly nice crunch when playing with the distortion on your amplified. Having said that, for what you pay the overdrive is AVERAGE at best! You would be better off buying a different pedal specially designed for overdrive. My advise STAY CLEAR OF THIS PEDAL!

My set up is a Kramer 5150 EVH, with digitech GNX3000 Fx's box and a marshall mg 50watt amp.

well for the hole 1 DAY that I owned this pedal before taking it back for a refund it did not break.

overall this pedal was a total dissapointment! horribal distortion... average overdrive and one BIG waist of money!

The mode switch, The Gain and Volume Dial and the Bass and trebble dials are self explanatory. However the Contour dials did and still do confuse me.

I literally fluked the settings on those. The manual kind of helped but it comes down to you interpreting the instructions properly

Im running my Epi Zakk Wylde Bullseye through this and into my Marshall Zakk Wylde Ministack.

For starters IMO you can forget about the Distortion mode.
Its just way too compressed and Muddy.

I use the O/D mode and have the Gain at full 100%
Volume is set as per needed to get equal volume between on and off.
Bass is at full 100%
Treble is a little past 1 oclock (about 70%)
Contour Frequency centre knob is just past 9 oclock (about 20-25%)
Contour Volume outer knob is at 5 oclock (about 95%)

With these settings and my amp set at Bass 8, Contour 4, Treble 3, I have pretty much got the sound I was after.
This sound I seeked lies somewhere Between "The Darkness" and "Zakk Wylde"

I will admit the sound I was able to get was a little more on "The Darkness" side of things than "Zakk Wylde" but I am very happy and think its anything but the Harsh and Brittle tones others have claimed it has.

I actually removed my Boss MT-2 Metal Zone from my pedal board to put this in its place.

I am no longer into the hard edged metallic sound it puts out and wanted something smoother which this gives me.

Yeah Definately If the Marshall tone is not your bag then this aint the pedal for you but if a nice JCM800 roar is then go ahead and try this pedal and I reckon you will be satisfied.

Im only giving it an 8 though because I really was disapointed by the flat muddy tone of the Distortion mode.

I dont gig any more so this pedal wont see much if any road action. But I would say its built tough and well.

Cant comment. no dealings in regards to this item.

I did once contact Marshall for an email or E-book of the manual to the ZW mini stack. cause i didnt get one whan i bought it (display stock) and never heard from them.

I play Metal and Hard rock. Kind of Sabbath meets Tool meets Black Label Society. This pedal gives me the tone I wanted for that.

I thought of maybe a Boss DS-1 but had some people tell me they were too weak and not too good for heavy stuff. I kind of just had a brain click one day and thought id try this pedal out so I got on here and read some reviews then tried it out and like what I heard.

As I said in my review of my SV-1 Supervibe I REALLY like the way the switch is mounted on an angled face and the knobs are set back on a lower platform which keeps the swith very accessible and the knobs out of the way of stomping feet.
I have some MXR pedals too and with the flat mounted switch and knobs all on one flat surface can sometimes = squashed knobs.
A big + to Marshall for the style of switch mount.

Only minus is that the Chrome knoba and small position markers make it hard to see where ya are dialing them in at.

Probably the most difficult part of my gear to control. Too many knobs, doing almost nothing but F***** up my sound. It takes me too much time to make a good sound. The volume knob is very difficult and it causes me troubles during gigs because there is a volume difference between the clean and the dirty channel.

Its o/d is almost perfect. I would give a 10 if it was only for o/d. But the distortion is !@#@&$*%(.
But, in general, it's got a pretty nice sound.

It is reliable! Made with metal, it's built like a tank.

Never dealt with them.

Really easy to use. Have to be retarded to not figure it out.

I was completely shocked at how good this sounds. I bought it for $40 on a special sale but definitely worth resale. It's very versatile all the saturation you could need. If you know how to manipulate it with the settings of your amp, you can get any sound you want. I'm playing with EMG's through a fender hot rod deville. EMG's are going to give you a much hotter saturated sound as well, so that's part of the reason there is so much saturation.

so far so good

never used

nothings perfect.

This pedal is relatively easy to use, although the contour / frequency knobs can be a bit tedious if you haven't used anything similar before. The manual is pretty self explanatory, gets to the point and even gives you a few instructions for different sounds.

I WAS using this with my Jackson JS30RR rhoads v, into a randall 75 watt amp. It's not even close to the level of distortion i expected / wanted, at best you will get a hard rock sound out of it. I play thrash metal, melodic death, and so on so i needed something with a little more grunt. Other then that if you are into blues / hard rock i highly recommend it, great sound for those genres.

I can definitely depend on it, most solid pedal i have ever used. Built like an absolute tank, and i would have total confidence in using it without a backup.

Haven't dealt with them.

I play metal and surprisingly this really doesn't deliver. I expected it would be a great choice for my genre of music, but i suppose in the end it wasn't. If it was stolen i wouldnt replace it, seeing as A) i have a boss metal zone on the way, and B) i'd just get something else.

7 knobs to tweak make this pedal not the easiest to use upon first sight. On the other hand it is the most versatile distortion/ overdrive pedl I know and it is very easy to get a good sound out of it, no matter which guitar and which amp you use.

So for those of you using a standard configuration like a Fender Strat through a Twin Reverb or a Les Paul through a Marshall JCM 800, this pedal might be confusing. For all the others this pedal is what you need. It can give you a first class overdrive and/ or distortion sound with any quality guitar and amp, you might use.

I am using this pedal in front of the "normal" channel of my VOX AC30CC1. I am playing Rickenbacker and Burns guitars. The sound quality of this pedal is superior. I have compared it to many other pedals: VOX Cooltron, several BOSS pedals, several Ibanez pedals, Hughes & Kettner Tube Factor, MXR Distortion etc. - the MArshall Jackhammer was by far the best sounding and most versatile pedal of them all. You could get a similar sound out of a BOSS pedal - but only with an additional equalizer.

I have owned it for about two years, so I cannot tell yet. But it appears to be solid as a rock.

Great. The best distortion pedal on the market as far as I can tell.
