Roland JC-90

I purchased this amp new in 1995. 2 channels, reverb, chorus, distortion. Effects loop and headphones jack as well.

Rating 7 with the strat
5 with the 335

I was initially impressed with the sound of my American Standard Strat with it. I soon discovered that I could not push the volume past 5 as the speakers would begin to fart with the low frequencies. However my amp was always miked so the volume issue was not a concern. Actually it is a pretty loud amp for it's size.
With my ES335 I can get a decent jazz tone at a low volume but as soon as I start to turn the volume up the speakers fart and the low register sounds bad. Extremly bass heavy. I have tried every combination with the eq that I could think of but it just sounds poor. If I turn the amp voulme past two the head begins to rattle. (only with the humbuckers).
The distortion is totally useless but the chorus sounds very good.

Everytime I tilt the amp to place it in my vehicle the reverb stops working and I have to tap the reverb box with my hand to get it to work again. It does not appear to be a problem with the connections. More like the springs get hung up on each other and won't vibrate. Now the plastic nuts which are used to hold the 1/4 inch connections in place on the back of the amp are breaking off due to, I guess, dry rot. Plastic and metal just doesn't mix.

Never called for support

Overall I think the amp has a nice clen sound but only at lower volumes. The speakers can't handle the low end. The construction could be better but at this price point I guess it's all you can get. I have been looking at other amps lately and I am discovering that anything you get in this price range is going to have cheaper components and hardware.

2002, I think.
Great for jazz and country.
Excellent tone shaping.
I play in restaurant and pub type settings with crowds of generally 50 or less. More than enough power, obviously.
I'd like a vibrato (a la the JC 120) or tremolo, but it's more than enough for jazz and country and ska and even surf or rockabilly. It is also good for punk, but I don't publicly use it for that.

Sublime clean sound. Best that I've heard in 30 years of playing, anyway. The chorus is has a liquid quality. The true stereo of the speakers makes it shimmer.

The sound is fairly directional, midrange-friendly, and the amp takes effects well (particularly delay, compression, and so on).

I've used both a Nashville Telecaster and a Heritage jazz guitar with it. Both sound exactly as they should through this amplifier and better than they do through any other amp I've tried.

At the last engagement I played, several people came up to me to comment favourably on the sound. That's the acid test.

So far, it has been reliable.

Aren't all big companies terrible?

I chose it over a Fender because the sound is less commonplace in the guitar world. I can't afford a boutique amp, otherwise I'd try that. I'd say it's better than the particular Polytone that I tried, but that was a used amp, so that might not be fair.

Roland JC-90 -- super sweet clean sound -- can be clinky or trebley sounding with the reverb cranked.. Definitely a one or two trick pony here with this amp-- either super clean, or stereo chorused clean-- I never use the distortion-ever, and roland should just do away with it on this particular model- but I guess it is tradition to have it there..
It would be nice if this amp had a tremolo effect like the JC-120-- or possibly a phase effect(ditch the distortion already).
What is great about these JC amps is that they do a great job with stomp boxes/ effects pedals -- and that is how I get away with using this amp as a gigging amp for several different rock acts.

Never had any problems with hiss or hum.. A bit of operation type noise-- very small. Although solidstate, this amp has an intangible sound realm of it's own- that I feel other solid state amps miss.. This amp is great in that you can have a super clean chord sound- which I feel is very aesthetically rounded, pure and crisp-precise-- and then rely on pedals for crunch and lead sounds.. I usually run an armada of pedals in a BCB-60 case at gigs- including BOSS- turbo OD-2, BOSS dist/ OD, Blues driver- for chord crunch, digital delay-6 - depth on solos, analog delay, digital reverb..
One thing about the sound on the JC-90-- is that it is super directional-- there have been many nights where the bass player has to dodge the signal path -so to speak..
In closing, although I love the clean sound of this amp-- it does not quite have the breath of a tube amp, but it still has an awesome clean tone that is unmistakenly JC..

I guess some of the other reviewers have commented on shoddy parts etc.. Personally I don't like the plastic input jack screws- which have a tendency to crack. But for overall Reliability here lies some of the beauty of this puppy though-- it's toughness-- yeah it is kind of made of pressboard- but all the reinforced corners and sidetrim make this a tough little pissant.. no microphonic tubes, or temp. concerns. Really don't hav to baby this at all- like some of he boutique amps where you have to standby for 10 minutes-- on shutting on & off.. I gig without a backup and have had a good run of 3+ years gigging with it..

N/A ..no repair issues

I own some other amps-- a 1960's Gibson- all tube saturn(styled like a fender deluxe) which is a sweet smooth ride.. Play mostly on a Gibson Les paul Standard with burstbuckers, and a Fender strat plus deluxe..
I have been playing for 26 years -- fun fun fun.. If my JC was lost, stolen, or destroyed by some angry biker at tomorrow nigt's gig--- I really would like to have a kickass new fender supersonic- or a mesa lonestar-- maybe even something from the fender hotrod series-- also I would have to consider a JC-120...
rock out-- rock on...

Made in 2005, solid state, single channel, very clean, transparent sounding amp. 2x10 inch speakers in stereo. I play acoustic and indie type music, I find this amp is perfect for that. I use a MIM fat strat mainly but have also used a Yamaha Pacifica 112 and a Peavey Generation with Piezo acoustic pickups. This amp has handled them all well as it really allows the tone of the guitar to come through. The chorus is excellent and can be set to either fixed or user defined with a rate and depth knob. The reverb is perfectly adequate without being outstanding. The distortion is not to my taste and I don't use it, it sounds a little too brittle and sterile to my ear. I think it might fit in with a more techno/industrial style as it has a mechanical feel (if that makes sense) rather than an analogue smooth tone which I prefer. I use this amp for home practice and in rehearsals with a very loud drummer and it keeps up easily, I have never had the volume past 4. There is an effects loop (stereo return), headphone (cabinet voiced) socket, each of the effects (distortion/chorus/reverb) can be footswitched. High and low input sockets, stereo line outs. Bass, Mid, Treble and High Treble tone controls are very effective. I can shape my sound easily and find I have to back off the High treble or the strat tone can take your head off.

Fender MIM Fat strat(H/S/S) unmodified, works very well with this amp. This is a great simple amp with few bells an whistles which is why I like it. I have tried a few more "feature packed" amps with effects/amp sims etc built in and personally found I spent more time fiddling with the controls than playing. I do not find it noisy at all even with the strat selector in positions 2 and 4. The tone remains true when you turn it up- no break up.

I have had this amp for around 6 months and it has been regularly lugged about in my car. It has never caused any problems and seems very solid and robust, it has detachable casters which are a bonus as it is reasonably heavy- it is a one handed amp-just. I did buy a cover for it which I think should be supplied by Roland.

Roland had forgotten to include the casters when I bought it, one phone call sorted it and they were very helpful. 1 year warranty.

I have been playing, on and off, for 25 years and after a lull have recently started playing with a band again which is great fun. I use a Boss GT8 straight into the amp for the effects only, I don't use the amp sim part. I have experimented with the GT8 going into the stereo return and using the amp sims and it worked a treat, so I would recommend the amp for amp modellers also (I think Roland use the JC range amps to demonstrate the GT8 so no surprise there really). I just like the clean sound of the amp though and prefer the simplicity of just using the effects on the GT8. Get a stomp box for distortion/overdrive rather than the onboard one and this is a great amp.

80W, solid state, loud and clear, 2 10 inch speakers, spring reverb and beautiful chorus effects, mild overdrive capability.

I play an American Strat (SSS) and a Mexican Tele w/ upgraded SD pickups and vintage Fender bridge. I adore the sound and tone from this amp. Because the clean is so pure and clear every adjustment on your guitar is reflected in the sound through the amp. The built in distortion is mild, but it sounds great distorted with the right pedal in front. The built in reverb is not overly strong, it's restrained and very linear from 1-10, and the built in chorus is legendary for good reason. It's extremely loud and I don't think the clean ever distorts on this thing. It hums a bit, but so does every other amp in my house.

Haven't had it long, but it's solid state and built by Roland USA, so I'm relatively confident.

Been trying to register it through the Roland website but have yet to receive the verification e-mail they claim they sent. I'll call and see if I get better results.

I've been playing just over 10 months, after meaning to take up guitar for at least 10 years. I have much more talent at gear knowledge than I do at actually playing guitar. I love this amp, especially at the price I paid. I traded in a very nice Vox AD50VT (great amp) to get my very own Jazz Chorus and have no regrets. I've been looking at solely tube amps for the last 3-4 months and nothing under $1200-$1300 dollars even came close to the sound quality of this Jazz Chorus. I would buy another without hesitation. The built in distortion won't do high gain, but I think most amps sound best with an overdrive or distortion pedal anyways. Only thing I really miss is the vibrato/tremolo effect you get on the JC-120, but no complaints at this price.

90's JC-90
Use as slave and/or acoustic guitar amp.
Only use the chorus, for dual amplification and spatial effects.
Made my first album exclusively with a JC-120 (Hard progressive rock)
the engineer freaked!
Headphone jack?....Huh? No extra fatures required for my proclivity.
Distortion is WORTHLESS, reverb is "decent" but different. Salesman warned me beforehand though, warned me about the 120 also. That's not why I bought it. Read up!

I use this amp in conjunction with a Laney VC-30 1x12(Open back) class "A'" tube amp with a separate 1x12 Laney (closed back cab) slaved into the JC-90. The dichotomy of the two separate 12's and the stereo 10's on the Roland create great spatial effect, onstage or in studio. Still use a Roland GP-8 for effects, Roland products meld with other Roland products quite well, quite well. Tube saturation from the Laney's combined with the wonderous clarity of the Rolands essentially tri-amped with only parametric equalization give me what I would consider a very professional sound, with tonal capabilities that could not be acheived by either amp alone.

I use a "Vaughn" Strat, Nashville Tele with a Parsons B-Bender, and a Les Pul Studio.

Add your compression after the power amp signal, "Star Ground" your Strat(Very Important!) Ground and solder the cavity of your Tele and leave your Les Paul alone. That should reduce noise and hiss much more effectivly than "noiseless pickups" without sacrificing tone.

Roland Chorus and clarity is just that,ephemral, a thing of beauty.. Nothing else sounds like it, but that's all you get. Perfect for jazz and/or acoustic, slave a decent tube amp for some cojones, kick in your effects for kickin it.

I'm not certain about the JC-90, but several times I took a 25 foot walk with a 20 foot guitar cord, my JC-120 was none the worse for wear.

As I have stated in previous reviews, find a good local tech!
Make him one of your best friends. A doctor of sorts.
Hell, by the time you pay shipping to the manufacturer, wait for shipping back without even hearing it, a decent amp tech will already have you back in business.

Even if it's a two hour drive to get there, it's worth it.

Aha, the math quiz....playing since I was 12, now 47.
I would replace if lost or stolen, a JC-90 or a JC-120 is always good to have around, they make everything sound pretty, unlike a class-A tube which is unforgiving. But oooh, the combination and ability to switch between the two for around a thousand dollars...PRICELESS.

Pretty simplistic, volume knob and EQ with distortion, reverb, and chorus. For the most part I don't use the effects as the sound is great without them. Hi-treble adjustment is useful especially when playing in dark sounding rooms.

Clean sound is great: punchy and round with very solid and clean sustain. Many people have bashed the reverb but I think it sounds fine. 3 spring reverb tank sounds natural and not overly loud or poingy. The chorus sounds great, better than any i've played with before, but it tends to overly exaggerate the treble range, so eq may need adjustment. The distortion is lifeless, but can be useful if never turned above 1.5. Unlike the chorus, the distortion empasizes midrange a bit much and high notes sound clean unless on high gain settings. I use it at home and at practices, sounds great with effects, and I have yet to need to go above 2 on volume.

Only had it for a few weeks, but built solidly and seems dependable. The hiss isnt terrible and its on and off depending on other electrical gadgets nearby.

I've been playing for 6 or 7 years, I use both Les Paul and Strat type guitars, both sound great through this amp. Strats are clear and punchy (bass at 10), and les pauls have a very good crunchy bite whether clean or distorted. I like its simplistic controls and sound: amps with the letters DSP in the title never live up to expectations in my opinion. Doesn't offer dozens of gimmick effects, but sounds marvelous clean, with chorus, or with any good outboard effect.

Please see my last 2 or 3 posts to bring your self up to speed regarding this product. There are dozens of other reviews about the features.

In spite of it all, I still like the sound and tone of a JC.

Ok...here's where I'm at with this amp...No more warranty nonsense. The amp goes back to my favorite local amp tech again who has it for awhile but in the end...he fixes it! He replaces the left amp muting FET and plays with the speaker wiring and voila!; I'm back in business. The amp works fine. No loud noises upon power up, no more blown sounding left-sided speaker. Amp functions like it did out of the box. I do not see using it for much band gigging anymore. It will now be designated to the occasional solo guitar cocktail hour or practice session, recording session or acoustic/electric gig. In the end Roland did not come through for me at all. Screw them and their lousy warranty repair centers! Do not spend the money on this amp if you are looking to use this on a regular gigging basis with a band. It's better for the home or studio. Thank you Dave at Dave's Sound Repair, Whippany NJ. You are the best!! Roland should authorize you for their warranty work and you alone!!

OK...no more Roland bashing and in all fairness I've never had a problem with Boss gear and I've used some of it for 25 years. Maybe the key is to stick with the older JC 120's and 77's. I will not ever buy another Roland amp big or small. I'm sorry but they've lost my business. I will rate this a 4 as one Roland warranty repair center tried to fix this amp, but in the end I think they just did not want to put the time and effort into it. Apparently, Roland doesn't pay them for more than a small amount of labor so they either fix it in an hour or not at all which is what I think happened here. A 3 to them for at least trying.

Read all the reviews and decide for yourself but in the end you can do alot better with other amps and companies. I spent $550.00 for the amp, $30.00 for a cover and $60.00 for switches. It cost me $100.00 for a new reverb tank installed and $90.00 for the latest repair. It also ran me a few bucks to replace the one pop-out caster that fell out after a gig and got lost. The amp is not even 3 years old and most of its time has been spent in the shop after it's first year. Do the math...you could buy 2 amps from another company or even a real nice tube amp!!!

2005
Love the styling. I wish it had less weight.

4 Hiss terrible I sent the first one back, and the second one (Brand New) hiss's worse than the first and I even took it across the street to my neightbors and it hissed..so it ain't nothing to do with my wiring. Ran 3 guitars through it and still terrible.

Nope give it a 4

N/A but American Musical Supply company is great working with me. Can't say enough about this company, these people are jam up.

Been playing 40+ years, fenders(Mustang,Strat(both) Scheter,Wilson Brothers, Gretch..Fender Tremolux,Twin Reberb, Tech 21 TM-60, Vox AD 50, you name it I played it..this thing has a good sound but who can live with the hiss.

I only wanted to write about the sound quality.there are plenty of other reviews on features,reliability,etc.If you want to use this amp for anything other than clean sound I would suggest you buy something else.I agree with other reviews that rolnd should just forget about the distortion feature completely,it's worthless.I was amazed at how many players wrote all this stuff about using this amp for zztop sounds,Blues sounds,or any other gain type styles.Anyone with any experience at all should know better than to try and use this amp for anything like that.It just was not designed for that stuff.IT IS A JAZZ AMP,AND I DON't MEAN FUSION JAZZ,I MEAN TRADITIONAL JAZZ(Jim Hall,Joe Pass,Freddie Green)Don't pay any attention to reviews which were obviously written by rockers and headbangers.Now to the sound.For clean jazz the tone is superb.It really brings out the tone differences from one box to the next.If you have a box that sounds lousy,it will sound twice as lousy through this amp.If you have a decent quality instrument and play chord/melody style as I do,you won't be disappointed.The amp's equalization controls(Hi-treble,treble,mid,bass)allow for great tone shaping and lots of versatility.The stock speakers are decent,but I think an upgrade to something a little more high-end may be worth the buck's which I plan to find out soon.I traded a poloytone for this amp,and although polytone also makes a great sounding clean amp,they are not as versatile as the roland.The chorus is in stereo and pretty much tops any accessory pedal chorus I have ever heard,if that is you thing.(Not mine but I do on occasion use the chorus if the audience is not to discriminating or full of purists.)The 80 watts of power gives enough headroom to keep down the feedback in most situations,although I have had to add 1/12 speaker cabinet for extremely large rooms.All in all the JC-90 is a great amp for CLEAN JAZZ.I heard this amp once described as nuetral and have found that to be a pretty accurate description.I'll close out by saying(again)if you have a lousy toned guitar it will sound really lousy through this amp,but if you have a decent instrument you will probably be pleased with this amp.Also,let's face it,we jazzers in general don't have a great number of choices for amps and boxes anyway.

See my previous posting from January, 2005. Ok... it took one repairman 5 weeks and he never even looked at the amp. I finally found an authorized Roland repair center and it took them approx 3 months to indicate that my problem is unique to my amp. Apparently, Roland alleges that they have never heard of this problem and they want me to ship it to them at my expense to take a look-see. C'mom guys...if this is under warranty then you pay for the shipping!!!! On the other hand, the repair shop feels that this problem will not get worse and should not effect(blow-up)the amp. Apparently, what is happening is that when I power up, the amp sends a small voltage surge to the speakers causing a static-like noise that lasts around 10 seconds. Forget the fact that the amp worked fine for over 2 years before this started. I really feel like Roland won't stand behind this problem. If this is due to manufacturer defect, then I should be entitled to a free repair or a replacement. It's not my fault I live 3,000 miles from where they are!! They had no problem taking my money when I bought it in the first place. Anyway, after getting the amp back it sat in my garage for 3 months and recently I needed it for a small gig. When I powered up, it still made the noise but otherwise worked fine. I can't help it but I still like the sound of this amp. I did bring a back-up amp which is something I have never done in 25 years of gigging(thanks to Peavey amps). I still think this is the beginning of the end of this amp but I guess time and further gigging will tell. I was going to sell it but I'd rather not stick someone else with my problem.

Boo...hiss...lousy as always. You stink Roland. The customer service rep couldn't have been nastier when I tried to find a valid service center that was within 50 miles of my home. By the way, you need to "police" your alleged repair centers as one of them would not return my phone calls for 3 weeks before you finally advised me about calling another one. What good is a warranty when you're gonna clip me for shipping and your factory repair shop will hold onto the amp for months and then tell me that you could'nt find anything wrong with it. Time is money!! I already paid over $650.00 for this amp w/a after-market cover and one FS 1 switch. No problem making the sale; every problem backing it up. BUYER BEWARE!!!!!!!!!!!!

8 for sound.
7 for features.
4 for reliability. (The noise problem plus I replaced the reverb tank that died. That was $100.00!!)
1 for Roland treating its' customers' badly.

My JC-90 was made sometime between 2000 and 2003. Read other reviews below if you want to know what features it has. In my opinion it has two main sounds: Clean and Chorus. Reverb effect is decent. I will not speak of the distortion until later. I play in church, and this amp has well more than enough volume. I usually don't go past a quarter turn on the volume knob, unless I want a bunch of gramma's to refuse serving me sandwiches at lunchtime. I enjoy the headphone jack. It gives a pretty good simulation of what the amp normally sounds like through the cab. The line out, however, is fairly noisy. Better off micing the amp or using a noise supressor perhaps. The equalizer knobs are useful, however don't think that you'll get a completely different sound out of this amp by playing with those knobs. Like I said earlier, it basically has two sounds.

First and foremost, you must realize that this is a "Jazz Chorus" amp. It is a "clean" amp. It is not made for distortion. You either like the sound of this amp or you don't. I happen to love the clean and chorus sounds from this amp. That's why I bought it.

I play in church, so the chorus is perfect. I play with an Epiphone Les Paul standard through a Boss SD-1 Superoverdrive and an MT-2 Metalzone. I think the clean tone from this amp is very warm and full and I love the true stereo chorus effect on this amp I knew that the distortion was pretty crappy on this amp before I bought it, however after a while I thought it would be nice once and a while to jam some rock tunes with my friends. So, I have found that the Boss Metalzone pedal will actually give a pretty decent distortion if you tweak it right. It will give you a much beefier crunch than the crappy and thin onboard distortion. The onboard distortion can be used on it's lowest setting to make the tone a little dirtier if you want, but if you want slightly more electric and dirty tone, you're better off getting a Boss Super Overdrive as it will give you a better sound and more versatility if you're willing to pay the extra money.

I bought this amp because I loved the clean and chorus sounds. It is a clean amp and if you buy it you should be aware of this. If you're looking to play a lot of distortion and rock, punk, or metal. Then you're better off getting an amp that's made for that type of music.

However, if you're in my situation, and you already own this amp and you want to get some good distortion tones out of it for jamming some rock without going out and buying a new amp, then the Metalzone is the way to go. It's the closest thing to making this amp sound like a Marshall.

Only had it for a few months, hasn't given any grief so far. However from reading some of the reviews below about the inside components, I'll be sure to baby this amp as much as I can.

Never had to call them. Yet.

Like I said earlier, you either like the clean and chorus sounds or you won't. I love them. That's why I bought it. If you want heavy distortion sounds then don't buy this amp. However if you already own it and are wondering if a good distortion tone is possible from this amp, then try a Metalzone. It does a good job.

See my 3-18-04 review... As you may have guessed from all the other reviews, you will either like the sound of this amp or hate it. I still personally like it but in addition to the bad reverb tank, it has now developed a new problem. When I power up I get a loud noise similar to when you whack the reverb tank. It fades after about 5 seconds. This is with the reverb volume and the master volume off! It used to do this every so often but it now does it every time I power up. Apparently, something is frying out and my electronics repair guy has not been able to figure out the why and how after having the amp for 3 weeks. I am not sure I can trust this amp not to burn out on a gig or during transportation to one. This amp is only 2 years old and already has been in the shop twice. I am back to using my trusty 20 year old Peavey Stereo Chorus 400. Unfortunately, the weight is killing me but the Peavey continues to work flawlessly. I know I will take a beating on it but if this problem can not be assuredly repaired, I will be forced to get rid of the Roland immediately. As a pro musician, I'm not going be messed up by a piece of gear on a job. I also am not carrying 2 amps to the gig. I know as much as I love the sound of the JC, I will not, no way, no how, purchase another. Roland has most likely lost my business. Sometimes you just have to sacrifice some tone for product quality.

In response to the posting immediately below: I am the "previous poster" to whom you allude. I think you've countered with a fine point regarding cheap parts. Perhaps my amp, at two years old, isn't old enough to serve as much of a reference point for this model--by which I mean, it hasn't yet had enough wear and tear.

About the quality of older Rolands, I had a JC 77 years ago which gave me some problems (chip, reverb, on light, some speaker buzz). While I have certainly played through a 120, I've not owned one. I agree they sound better. They should, of course.

Anyway, perhaps the best support for your opinion is the fact that I seem to have a good 90, while you don't: if the quality varies that widely, that certainly seems to indicate inconsistancy or poor production or parts or quality control on some level.

I still rate mine highly (so far) but I do baby it a bit.

Follow-up to my review below: well, I've had the input jacks fixed. Just as I expected, the whole circuit board had to be replaced, not just the jacks themselves. I'll stand by my original comment: these amps are made of CHEAP & FLIMSY COMPONENTS. Roland has really cut a bunch of corners here. Just the other day, I had a chance to play an old JC-120 again at a studio, and I am more convinced than ever that the JC-90 is much, much inferior in both construction quality and sound. Don't buy it. Spend a little more and get the JC-120. By the way, to address another poster's comment, as a guitar repairman, I am the last person on earth to blame the manufacturer for the condition that most of my junk comes to me in. Precisely because I have spent 20 years taking broken guitars and restoring them, I have learned to appreciate strong, durable components and construction quality. Both are lacking on the JC-90. Sure, this amp is great when it's brand new. Just hope you never have to fix anything on it a few years down the road. The JC-120 is a nearly bulletproof workhorse. The JC-90 isn't. End of story.

I have had this amp for a year and one half.
It has had no problems whatsoever. Has Line out, headphone jack, Stereo effects loop, 2 ten inch speakers, best chorus out there. It is loud and clean.

This is a good amp if you want a clean sound.
Another poster here said the reverb was digital and fakey. It is not digital. It consists of an Accutronics 91/2" (short) side mounded 3 spring tank ( # 8DB2C1E). The Reverb is a bit lackluster but is easily corrected by ordering and replacing the small tank with a 17" bottom mount tank (# 9DB2C1B). This costs $29 plus S/H direct from Accutronics ( http://www.accutronicsreverb.com/ )and lends a very lush sounding reverb. Best $29 investment I have made. You will have to lengthen the RCA Reverb tank cables or do what I did... use a pair of 2 or 3 foot stereo cables with RCA Jacks and get a $6.49 adaptor from Radio Shack that mates the two sets of cables easily together. No other Chorus has come close to the sound of this amps but you can over do it. I typically never go above 1/3 on the rate and 2/3 on the depth controls. The distortion section is lousy and I never use it. For those who want a set of speakers that make this amp really shine...try WeberVST Michigan's (www.webervst.com)....EV sounding, big, bold, clean and smooth without sounding the least bit sterile.

Never given me any trouble for the last 1 1/2 years.

Have only used them to order schematics for the amp. Very fast and courteous.

I absolutely love this amp. I have compared it to Fender Twins, Deluxe, Super Reverbs and Pro Reverbs. For clean it does well, however you will never get that good ole Tube overdrive sound here.

Follow-up to earlier review. This is the cat's arse for jazz. I use it for solo playing. All the options I could want. It also works well for ensemble playing, accoustics if needed, and it takes effects very well if you're into that sort of thing. Complete sound shaping with 4--count 'em, 4--tone knobs. Much more versatile than bog standard tube amps. Not that I'm panning those, I just think there is much more sound pliability than with, say, a typical sounds-like-blues-no-matter-what-you-do Fender. This responds well to those metal and punk and psychedelic effect moments, too.

And who doesn't dig coasters on the bottom of thier amplifier? Sillies, that's who.

But solo jazz is this thing's forte. I mean wow. A truly professional, world class amplifier. The only hi fidelity amp I've ever heard that is commonly available. Polytones are great, too, but harder to come by, and they have much less variety in their tone. Roland's chorus is a constant revelation to me. I've finally opened my mind to chorus after years of shunning it. The reverb is deep enough to cop the feel of...I don't know...say...the Cowboy Junkies' Trinity Sessions. Probably best to go back to yer bluesy old Fender for surf, though, as they are still the king of that stuff. Also, that Fender tube shimmer is just damned sparkly. But the JC 90? It's a very rich sound that spans the huge distance between New Wave and Bebop era jazz. Eminently useful. The quality of the sound is instantly evident to everyone in earshot. If you are good, everyone will know it. If you are bad, though, everyone will know it. The ultra clean, clear, balanced tone demands that you feed it a commensurate level of quality. Or it will shame you. Read further below to hear of some people's frustrations.

Much less fragile than its inbred tube-saddled cousins. A couple of years old and no worries to date.

No experience yet. If they ever screw me over, you'll hear about it--ha.

All ratings indicate a top value for money. Also, a karmic balancing for this amplifier's review column ratings is long overdue. This amp is as good as you are--no matter who you are. That's a boon to some and a curse to others, I guess. No, I'm not saying I'm somkind of Ed Bickert or Jim Hall. I'm saying this would be good enough for anyone.

Wow, a lot of the "guitarist" below have bashed this amp for sounding "flat" and not "tube" like. This amp is for jazz or a pure tone that lets your guitar and most importantly, your finger work shine through. I truly believe an amp of this calibur is only for seasoned musicians, not a guitar player who cranks their tube amp and plays "Power Chords". My intention is not to flame on anybody, but just to make people realiize that this is not a rock amp or a beginner's amp. Don't bash on a great product just because you can't provide some level of musicianship to the table or are clearly kidding your self of the type of product it is. Its not a tube marshall, not a tube fender, vox, mesa, dumble, whatever. Its a Roland JAZZ Chorus.

As below.

Personally, I find the lack of tremolo and inclusion of distortion is annoying. Why, with all the laughing and complaints doesn't Roland just STOP it already with the distortion? Why oh why? Have a MEETING, people. Someone out there translate this into Japanese so we can get some action. Happily I don't need or use the distortion. It just bugs me. Wastes space. There, I said it. Nice options on the backside, as it were. I mean, it's all there THAT way.

Jazz. It's a...um...Jazz Chorus. Please discontinue filling this section up with irrelevant assessments which skew reality: if you play blues, rock, whatever you want to call it, this is not your amp. Judging by some of the spelling, I'd hazard a guess some individuals can't read where it clearly states "Jazz Chorus". Again, someone please translate. Yes, it is flat. It's supposed to be flat. Flat is desirable if you have, for example, a nice-sounding archtop. It doesn't colour the sound as much as even a clean Fender, and that's what lets you hear more of the true tone qualities of your instrument.

So, rating it for jazz, then, and only jazz (because remember: that's all it's for, guitar-wise), this is great. I use it for solo guitar playing. No, not wanking in a rock band: playing unaccompanied. It is a tad boxish, but again, this is normally more desirable in a jazz context where midrange is often boosted rather than cut.

I generally loathe chorus, but this one doesn't make me wish I was dead. Not that I use it too much. I actually try the manual setting and dial in next to no rate (while keeping some depth) and then I still get that ping-pongy stereo effect to the sound.

Overall, this is unnecessarily powerful for my coffee house needs, but headroom is a good thing, and this is as small as I could go and still get the clean bass response I want out of my Heritage H-575.

Quite comparable--somewhat obviously--to the JC-77 I used to own 5 years ago. I confess I like this better than I liked that largely because my own ability to make noise with it has improved and matured. Please consider that yourselves when writing and assessing reviews. That and try on some realistic expectations.

This is from the dark years of Roland's JC-90 model (early 2003), but so far it's alright with gentle use.

It would be nice never to have to know.

I've played off and on since age ten (I am in my 30s).

Other amps I've owned include: Fender Princeton Reverb (silver face--overall a dandy amp); JC-77 (virtually identical to this amp); Fender Hot Rod Deluxe (surprisingly good clean tone, but not much clean headroom). For jazz it's as good as or better than any of these. But, again, only for jazz.

Highly sensitive to interference, unfortunately. These old-style circuit boards scare me, but not as much as tubes scare me. I like the idea of amp modelling, but I really don't need much variety in tone, and the speakers/sound quality usually seems to lack by comparison with something like the JC-90. Whatever. It's all subjective and I just feel like typing right now, okay?

As long as it doesn't break down, it does what it needs to. If you're too amp/tone fussy (if you are not a professional, I mean, and if you are, you are not bothering to read these ratings, of course) you should perhaps practice more. Or quit. You should be able to make most amps sound fine.

The JC-90 gives you good basic tools to work with. At least new. Oh yeah, that's another thing: watch for people who pan USED equipment and blame it on the manufacturer. It might be misplaced blame. At least in part. Just a thought.

The JC-90 is a one-trick pony. It has a good clean chorus, and that's the only reason for getting it. The "distortion" is a total joke, it can only muddy up the sound a little, that's all. Granted, no one buys the Jazz Chorus for distortion, but still. The reverb is terrible. The tremolo, as found on the JC-120, is missing here. It does have some ins & outs in the back, but those are useless to me. Would've been better if they had the tremolo instead.

I have always wanted a JC-120, but put off buying one for years because of the high price. I got a great deal on this amp ($200 used), but I am still disappointed. It's NOTHING like the JC-120. A vague approximation, not at all the same thing in a smaller package. Not the same sound, not the same quality.

My amp had a loose, intermittent input jack on the high channel. No problem, I thought, I've been repairing guitars for 20 years, I can replace an input jack. WRONG. When I opened this amp up, I discovered that the input jack - and all the other jacks - was a FLIMSY PLASTIC CONNECTOR PERMANENTLY SOLDERED TO THE MAIN CIRCUIT BOARD!!! The slightest sideways pressure from a hastily inserted guitar cord would tear it off the board, which is exactly what must have happened on my amp. And the only way to repair it would be to replace the whole board. The nuts are all plastic, too. I tried tightening a loose one and it simply crumbled. I put a new metal nut on, but was afraid to tighten it properly, as the whole assembly was too flimsy. So what is a simple, three-minute repair on any guitar or a quality amp is impossible here. It will have to be taken to an electronics repairman (used, no warranty) and will probably cost way too much. Overall, the insides of this amp looked EXACTLY like those of $40 chinese no-name solid state amps, CHEAP AND FLIMSY. I can't really complain because of the low price I paid, but anyone who paid full retail on this thing has been RIPPED OFF. I've had old Peavey amps that I've abused for decades and never once had a problem like this. I'll bet the old JC-120's that I originally fell in love with were also better made. Shame on you, Roland, for using such cheap and crappy components.

N/A

This thing will do for now, but I've got several other amps and won't be depending on the Roland. If anything happened to it, I would not replace it. I still have a soft spot for the old JC-120's, but I will never buy a new one now, knowing what shoddy components are inside.

Amp has decent features. The hi-treble control is really an adjustable brightness control. I had this years ago on a 50 watt Yahama solid state amp and it beats the usual "pull for brightness". Lets you funky up a strat ot take the high end down on a tele. Other tone controls are fair. Not alot of tweak-ability here. Has its own sound generally but works well with most guitars. Great chorusing obviously. Good stereo effects loop. Noisy direct line out. Better off miking the amp. Never used the headphone jack.

I play with a club date/wedding band. Has more than enough volume. Great for most styles of music except metal. I use it w/either a Les Paul, a 335 w/Duncans, a Strat w/Di Marzios or a Musicman Axis Sport. Sounds fine w/all. Sounds great for jazz, rock, blues, top 40. Built in distortion is lame. I use a Boss Super Overdrive that sounds great. The built in spring reverb died after 6 months. Its the small Accutronics. I have been using a digital reverb but also had a new Accutronics installed. I had the large 3 spring unit used for Twin Reverbs put in the amp. I highly recommend this upgrade. Again, this amp has its own sound. You either like it or hate it. Its not for everybody. The 10 inch speakers can start farting out if you like alot of low end and a Les Paul otherwise its real clean.

Have been actively gigging w/this amp for over a year and it has held up fine except for the reverb tank that died. This was Accutronics' fault. Very reliable so far.

This is a joke right? Roland is the worst to deal with. They have the top selling musical products in the nation if not the world and the worst customer relations. Go ahead, try calling them and talking to someone. I dare you!! Better yet try finding and dealing w/their authorized repair persons in your area. Ha Ha. I used to work for a music store years ago and they were lousy then. They haven't changed a bit.

I've been playing professionally over 25 years. I have only owned solid state amps and avoided tube amps. In comparison to the Yamaha and Peavey amps I've owned, this amp is as good and better in some respects. Super clean and I love the stereo chorusing. It has been as reliable as my Peaveys but saves my back as it only weighs about 40 lbs. It can cut a wide range of gigs. Upgrade the reverb or use a digital. Try different distortions. You will need to buy a cover from an after market manufacturer and the FS-1 switches are about $30.00 a piece. You can use up to 3 of them! I only use one. Total cost w/a cover and switches brings this amp up to about 650.00 or more. There are alot of other amps out there for that kind of money but if you like the big JC-120, this will do the same job and save your back. I like the amp maybe not enough to buy another but its good for a primary amp.

This is the follow-up on my new Roland JC 90 Chorus amp that has been sent back to the Roland-LA,CA factory for repairs 9/25/03, 11/26/03 and 1/09/04. My complaint has been that this amp's sounds are flat in tone, the Accutronics reverb was very poor, almost non-existant in sound and the chorus's oscillation sustain was equally poor. Even with all effect knobs turned up to near max.

On 3/2/04 the amp was delivered back from Roland in LA, CA. A week earlier, customer service had called and said the reverb unit was bad and they were sending it to their amp techs for repair. As for the oscillation on the chorus, I was told it functions like 2 other JC 90's there at the factory. Despite a new main board installed last January and despite many trouble shooting hours, the in-house techs find this amp working fine and per Roland specs. I really cannot think of one useful sound this amp can re-produce as vocals, keyboards, guitars, etc., all sound flat in tone, very dead and lifeless. The chorus and it's reverb is the same dead tone totally useless to me in music. I've never seen a chorus that one cannot dial in a desired speed, rate or depth yet it is with-in Roland spec's ?

I then asked how did this amp's malfunctioning reverb slipped by their in-house techs and their reply was that the reverb specs must have looked in line while they were trouble shooting it. So apparently the tech's read outs were in line so they never went any farther and did not test play it ? A huge tone minded company like Roland is that poor in quality control ? I don't think so !

All in all, the personnel there at Roland were courteous and tried to be vey helpful. I could not pin them down to specifics, they were well versed on what they say, telling me this is "old hat" to them. But bottom line is this amp and all JC 90 amps was just a dud from the word go or these amps were made this way per Roland's specs and I'm out $500. When the amp came back this last time from Roland LA on 3/02/04 it's reverb was not much better than it ever was, the amp's tone was still flat and the oscillation on the chorus was maybe a smidge better but far from what a new $500 chorus amp should sound like. I have owned and do own a lot of Roland effects and have no problems with their sounds. My wife owned a Roland Super JX10 keyboard and it was perfect. Being happy with these Roland products influenced me to try their amp line, never suspecting any problems like I found. Wow, what a mistake. I've tried to like this JC 90 amp and hoping I could make it work for me but it won't and I'm out the $500 that I spent for it. Rather than waste more time and money going legal on this, Roland's defense is that the amp is functioning exactly as the designed it, so we traded this JC 90 amp in on a new Peavey Studio Pro 112 which puts the Roland JC 90 to shame in sound and performance. Maybe you'd like this amp but try it out long and hard before you buy it. It just was not meant for me and the old country music, early rock-n-roll, rock-a-billy or early pop music that I play. I have no clue what music this amp was designed to be used for, the amp is flat in tone with a poor sounding reverb and distortion coupled with a non oscillating chorus. I cannot come up with any type of music that I'd recommend this amp to be used for.

I hate to bash any product but I feel this Roland JC 90 is very inferior and the Roland people never offered any exchange or any other solution. I've been playing for 50 years plus and this is the first totally useless amp, either tube or solid state, that I've run across. Congratulations to Roland !

I bought this amp new thru Zounds Music on 2/23/03 for $499.95 and have had nothing but trouble with it. The amp sounds flat, the reverb is weak and the chourus is intermittent regardless what speed or intensity I set the amp on, the chorus has a mind of it's own. It usually cuts the chorus effect short with a short decay. Other times it will work correct. When it does work, the amps sounds great but when it doesn't work, this amp is completely useless to me. The amp's reverb is also affected by the decay syndrome. It seems like it has plenty of power when it works right but those days are few and far in between. It seems rugged as the devil but I have not played this amp more than 10 minutes since I bought it. Most of the time it sets in the closet as I cannot use this thing. Finally I said this thing is under warranty and it has to be fixed, refunded, exchanged or something to satisfy me. So here we go !!!!!

I've sent this back once to their factory in L.A., Cal on 9/25/03 at a cost of $38.00 shipping and insurance out of my pocket. It took a few weeks before the techs got to my amp but when they did get to it, they said it was functioning perfectly. Very hard for me to believe this !! I told them what was happening and either to fix it, replace it or send me a refund. They were not interested in talking those terms but would install a new main board but this would take time as they have to order it from the main plant in Japan and this will take a month just to get it. BUT this will solve any and all problems. Yee Gods, more down time !! Finally gave them to go ahead and asked them to call me before they shipped it back to me with tracking numbers on the return freight so I can be sure to be home to receive it. Well those guys don't follow instructions very good at all as they returned it (postpaid) but I had no idea the thing was in transit. Luckily we were home to get it, but that miffed me as I felt they could at least tell a guy that his amp is being shipped. I see why they didn't call now, the thing is not one bit better now that it was before. Pretty sneaky move on their part.

When the amp got back here, I plugged it in and it was the same old problem, no sustain to the chorus, a lousy reverb and the amp sounded flat. I plugged my guitar(s) into my Fender Princeton Chorus 2x10 or Fender Yale Reverb and their tones and intonation are letter perfect, I mean just perfect. I then plug the guitar(s)into the Roland JC90 and these same guitars sound awful, putrid and flat. They sounded like I hadn't changed strings on them in 5 years. A horrible tone and F/X's no matter what settings are tried on the Roland. And this thing just got back from the factory repair shop !!!! I seriously wonder if they even touched this thing as it surely sounds like the same old amp to me.

Back on the tele I go to the main plant in LA, Cal. I played my amp over the tele to Travis, the main repair tech, no sustain on the chorus, flat sounding amp with poor reverb. He said he wants to grab his guitar and play it thru their JC90 amp at the LA plant and he will call me back. Amp Tech Travis calls me back only to confess that their amp does the same thing and that he is completely stumped. He will now have to get in touch with the main plant in Japan and see what the head engineers say about this and he is to advise. I told him I wanted this fixed, an even exchange for a JC120 or a refund if nobody can figure this thing out. That was November 26th, 2003 and today is December 21st and I'm still waiting for a reply. Their attitude is excellent but are they S-L-O-W to get things done, it takes half of forever. It appears that the Japan plant really RUNS things and L.A. doesn't make any waves, this is the opinion I get. Whatever Japan says, apparently LA does.

I'll be glad to let everybody know just how this thing shakes out. If I have to file suit to get my money back, so be it ! I don't think I'll have to go that far but I'm prepared to do so if needed. Right now the amp is setting in it's original shipping carton in my closet ready for their instructions or return. I told them to send me a prepaid UPS label which they did, so dummy me has woke up about forking anymore $$$ out of my pocket for repairs/returns/whatever. I will call Travis this week even tho it is Christmas week for an up to date report on what is going on. Stay tuned for further developements. I can't fault the staff at the LA plant as they are courteous and try to be helpful but sooner or later, this thing has to either get repaired, replaced or refunded. I'll let you know.

For features, look to other reviews...

I play jazz, and this amp is perfect for that, hence the name. The reverb is very sweet sounding, in my opinion. It's a bit noisy, but it's not too much of a problem. I play a telecaster and classical guitar through it, and both sound great. The distortion isn't great, but a little bit is good enough to dirty up the sound.

It's solid state, so I'm sure it won't give me any trouble any time soon.

I'm really happy about the tone that my JC-90 puts out. If it were stolen, I'm not sure what I'd do. I may save up and purchase a JC-120, but who knows. I'm not too impressed with the distortion, but that's not really what this amp was made for. Perhaps they could've used the space up with something more interesting, but then again a lot of people expect an amp to have some sort of built in distortion feature.

read the other reviews

The amp is terrible. It is possibly the dullist plain sound I have ever heard. It sounds like your not playning through an amp at all. It souds like you hooked a speaker to a guitar. The reverb on this amp REALLY digital and fake sounding. The only thing good about this amp is the chorus. But what good is that if the rest of the amp sucks. This amp is not made for any type soloing, it has no punch to it. This amp might be good for an acoustic guitar or Jazz hence the title, but nothing else. I don't know about the JC-120, but I've heard its much better.

Has 2 inputs-one high gain (normal) and one lower gain(for guitars with amplified or higher output pickups).
Has a Decent Reverb (Accutronics 3 Spring 9 1/2 inch tank) and excellent Stereo Chorus.
Distortion section.
Fx Loops, Line out, and Headphone Jacks.
2 Ten Inch Special Design Speakers.
4 Casters for easy moving.
80 Total Watts RMS (40 W x 40 W).
3 Foot Switch Jacks to control Reverb, Chorus, and Distortion.
3 Year Warranty on everything but the speakers. They have a 1 year Warranty.

This amp was made for Clean sound. Just right for Jazz, Country, Pop, or 60's Surf. The Reverb is Quality but do not expect it to be 60's Fender..that it is not! The Chorus is top notch that you would expect from the Company that invented it in the 1970's. The Distortion is pretty poor to say the least and I do not use it much. This amp is very loud. I do not play it over 3 at the max at home and typically less than 1 with the wife around. When I first got the amp I was disappointed in the overall sound and especially with the Reverb. It needed the speakers to be broken in. Now the amp just gets sweeter and the Reverb is starting to come to life. Guess the speakers being new were very tight.

From all reviews and Roland users comments I fully expect this amp to last many years of trouble free service. The warranty speaks for that. Most amps you are lucky to get 1 year at best.

Have only dealt with them to order Electronics manuals but found them to be very courteous and helpful.

I have played off and on for 38 years (started in 1964 at age 12..quit for 25 years in 1974 and as recent as 2001 decided it was in my blood and was something I not only wanted to do but try and do it right this time. I play a Gibson ES-137 Classic through the JC-90. I am really warming up to this amp. It gets sweeter every time I play it. Sound is good and clean..."Pristine" to be exact. I fully recommend it for Guitars with Humbuckers. Do not expect it to work well for lots of distortion. It was not made for that. I think the looks are "ugly". I was so put off by this that even though I fell in love with the sound of a JC-77 I could not bring myself to buy one. After 3 amps and trying to get that sound I sold or returned them and bought the JC-90. Sound means more than looks to me anymore. And this has plenty of it. Some have said it is not as full as the JC-120 with its 2 12 inch speakers and they are probably correct. I settled for the JC-90 because the 120 does not have FX loops or headphone jack but it does have a Tremolo mine does not. OH WELL win some, loose some. I had to decide was Tremolo and 12 inch speakers worth 250 more dollars to me...nope.

The chorus is ok if that is what you are wanting in a amp. Don't expect to go raise a flag on it's sound .The hi-treble is a waste of space...should have put a gain there .

I think it sounds pretty good threw a accoustic guitar . However, I play it threw a Mexican strat and it does NOT sound very good. The Mexican strat sound threw this amp can't get fat no matter how you place the knobs , it's as skinny as Olive Oil on slim fast. If you want a fat ,thick , bell tone...this amp fails badly . It's NOT a tube amp and it does not sound like one .

very reliable

I have not had a problem so far with this amp . I have had it several years . It is mainly a bedroom amp .

My oppinion is that I'm ready to change . I want a big fat sounding amp. This amp does not do the sound I want . However it is a very reliable .

Dont know what year it was made..bought it off e-bay. great clasic chorus sound, reverb is rich, but not as rich as i like it. THIS THING PUMPS FOR ONLY 80 WATTS. VERY LOUD!!!

I play a nylon string guitar through a Multi FX processor, WAH, and RC-20 Loop Station. I mix Flamenco, Bossa Nava, Funk, Electronica and Rock styles...mainly staying in the clean, or mild distorted range.

Built like a Roland..solid. I previously owned a AC-100 but found the sound was great, just not loud enough. For a used amp, still rockin..

No need....

I would reccomend this to anyone looking for a clean sound. The distortion is weak, but I have no need for it.

Stereo Chorus Amp, 2 10" Combo. Plenty of sounds to work with. LOUD.

If you want to hear this amp, visit www.mp3.com/yellowno5oh
This is a Mex Strat with a single coil standard pickup played through it. Beleive it or not, this is also the amp's distortion only! The guitars are doubled in our songs though. The song "Cosmic Riddles" shows both clean and dirty.

I bought this from an ad in the paper back near 1993. I didn't like the old look of it at first but the darn thing is durable. It also caught up with itself sound wise.

It was a fantastic value for me since I saw it when I was on tour in North Carolina for over $800. I also have a Dean Avalanche I and a Peavey Delta Blues Amp. You should hear these amps chained together with a stereo chorus pedal!

The stero chorus on this amp is very good , sound really good playing a acoustic style guitar . However my Fender strat sounds to twangy and not the sound I'm looking for .

The Fender strat I use does not sound worth a flip threw this amp. I tried it in a store on a acoustic Takamine which sounds ok . The Fender strat sound is twangy , dull on bridge pickup , It just can't produce the Blues,grundge , zz top sound I'm looking for . Maybe I expected to much when I heard it threw a acoustic guitar . If you want to play blues , country , Rock I don't recomend this amp

It is a rock solid amp , This is its best feature by far

this might be a ok amp if I had a different style of music I play like classical or something but NOT blues grunge Texas style sizzle I'm wanting . I guess I wanted a tube sounding amp and this is NOT it.

1999 model 2 10" speakers - i bot it because it has the best clean sound hands down also with the reverb turned to 10 it has a nice fender sound that i feel beats fender itself. the distortion is pretty bad and when turned on makes the amp buzz - i dont use it at all. its pretty loud and the chorus is great. great for clean players

i use a 52 tele with vintage pick ups and play in a danny gatton style the amp works perfect for it. the amp is noisy depending on the room -its very sensitive to other electrical items and/or amps. i find the clean works great at any level - the distortion creates lots of external noise and sounds poor too .

i've been playing 20 years - i would buy it again the jc120 is a bit more powerful but its loud enough for a band - i found it cleaner sounding than all the fender amps i wish it had a great distortion it would be the perfect amp.

This amp was manufacturered in 1999. The sales associated has a used JC120 that he just loved and heavily influenced this purchase. It is a very versitile amp. I play in a praise band. The sound caters more to a clean, undistorted sound. It is a bit noisey when used with the on board distortion. It has pleanty of wattage for stage performances.

I choose this amp because it has stereo line out plus a parallel effects loop. Three effects(chorus, distortion and reverb) are all foot-switchable (separately). The chorus is the best solid state I have ever heard. The dual 8" speakers really enhance the chorus. I am very happy with the value/price of tis product.

I use this amp mainly with an Epiphone Les Paul Custom with JB's in the treble and 59's in the bridge. The sound is full with smooth mids and lows. I also use a Peavey strat-style with three single coils. This amp produces an excellent sound with this guitar as well.

About six weeks after I bought this amp I began having problems with the Chorus. It was called intermittent defects. The authorized service center in my area attempted to fix the problem on two occasions without success. It still does not function properly. After talking with my dealer I learned that several stores in the area were having similar problems with this amp. The service rep also commented about the use of "cheap" IC chips in this amp.

When used direct to board with the both line outs one of the speakers go out. So if you attempt to use your amp as a monitor you lose half your volume and depth.

The customer service people were generally friendly and easy to work with. I can't say I was completely satified with my options for repairing my amp. Their only recommendation was that I send my 55 pound amp back to them for 3 - 6 weeks for repair.

This is an extreme headache. Now the $500 I invested in this amp for performances 3x/week has spent more time being repaired then connected to my guitar.

I've played for about 15 years. I own a Crate and a hot cabs acoustic amp. I've had the Crate for 10 years through gigs and lots of abuse and it has never failed me.

If this amp were lost or stolen I would probably replace it with a fender ultimate chorus and buy another JC90 later, as a back up.

Although I have had more problems than tolerable with this amp I am very happy with the value and features for the price I paid.

this is a real nice combo with chorus and reverb two 10" speakers
and a headphone jack. it has a stereo effects loop and distortion.

this amp is just what the doctor ordered. i play jazz and this amp
has the best jazz sound i have ever heard. it has lots of body
for a amp with 2 10 inch speakers. it makes my archtop sound
rich. i dont use the effects because i dont need them.

roland makes some of the most reliable amps around. with a jc you
dont need a backup.

never had to call them.

great amp that will give you lots of good clean sounds. i would
buy this amp again if it were stolen. you cant get a bigger sound
in any other amp this size.

80 WATTS OF OUTPUT POWER;40 WATTS PER SIDE IN STEREO.
CHORUS EFFECT, EFFECT LOOP, REVERB AND DISTORTION SOUND.
HEADPHONE JACK, AND FOOT SWITCH JACKS FOR CHORUS, REVERB &
DISTORTION, BUT NO FOOT SWITCH.

SOUNDS BOXY. LOTS OF MIDRANGE, BUT LOUD.
NOT VERY CLEAN IF YOU USE A GUITAR WITH SINGLE COIL
PICKUPS. THE HIGHS ARE JUST TOO MUCH FOR A TELE OR
MY ASAT.I HAD HIGH HOPES FOR THIS AMP. BECAUSE OF ALL
THE RAVE REVIEWS THE JC120 GOT, BUT THIS IS NOT THE SAME
ANIMAL BY A LONG SHOT. THE AMP BREAKS UP MORE IF I USE THE
CHORUS.

HAVE NOT HAD TROUBLE WITH IT AS FAR AS SERVICING GOES.
ITS SOLID STATE WHAT COULD GO WRONG.

NEVER DEALT WITH THE COMPANY.

I WOULD NOT BUY THIS AMP AGAIN IF IT WAS STOLEN.
I'D BUY ME A FENDER TWIN, OR SOME OTHER GOOD TUBE AMP.
I'VE BEEN PLAYING FOR OVER 20 YEARS AND THIS IS BY FAR
THE WORST AMP I'VE EVER USED. I HAD PLAYED THROUGH A JC120
AND LIKED THE IDEA OF A SMALL JC, BUT THIS IS NO SMALL JC120.
IT WONT PLAY LOUD AND CLEAN.
