Roland Jazz Chorus 77:
2 x 40 watts solid-state, two 10" speakers, aluminum domes, knobs: volume/high treble/treble/middle/bass/reverb + distortion (more to fill the space than anything else!) and (good quality) reverb + great stereo chorus with rate/depth, two inputs (high/low input) + independent inputs for the footswitches (distortion/reverb and chorus), and one stereo line out (not tested yet).
It's the small sibling of the JC 120 (and there's a smaller one, the JC50) with the same quality: 1 single channel... But what a sound: Perfect for jazz and even fusion with a good distortion or preamp (I use a v twin mesa boogie for distortion and it's awesome) and very, very solid! I only give it 8 points because the amp is very particular and might not be the best for everybody, but the clean sound deserves 11 points!
Very easy to use, the controls are precise and intuitive, you'll feel at home right away... The manual is easy to find on the Roland USA site, but it's useless.
The amp is very practical: stereo, with a marvelous built-in chorus and a good quality reverb (so no distortion), compact and not too heavy, no tubes to change (but it is nevertheless very loud for a solid-state amp), it's rock-solid. It works great with an acoustic-electric (Ovation CC057)
It's perfect for me but, fortunately, I also have the V twin: If you play metal it's not worth it, but jazzmen and fans of clean sounds in general should definitely listen to it (they are not very expensive secondhand: I've seen it on AF for $400... which is pretty rare): Some people have thrown away their Fender Twins after haring this amp... In my opinion, it perfectly translates the characteristics of a guitar: It doesn't alter the sound and the chorus is sublime... I don't know what to do with my Carl Martin now...
I was worried it would lack some power, but I was mistaken! It sounds really loud if you push it, it's perfect for rehearsals and clubs... But I'll say it again: The distortion control is only an embellishment (in the best of cases you can pump up the sound a bit... but I prefer to leave it at zero and use the V Twin), if you want some distortion you absolutely need a pedal, so I only give it 9 and not 10 points for that.
I just got it today, so my experience with it is limited but I'm currently under its spell...I'll update my review in six months to counterbalance my enthusiasm! lol
Being critical about it: There's a light background noise (but it isn't really annoying), I have 2 or 3 pots that hiss a bit, but if you apply some contact spray it's gone. Other than that, the amp is in very good shape, considering its age (20 years or more). The protection fabric has a small rip.
If you are looking for a clean sound, it's a great deal for the price (with a very, very good stereo chorus, which only adds to the allure! I'm doing a comparison with my Carl Martin, which is a standard reference, and I must say that I'm very impressed by the JC!), it's definitely its main strength! I was looking for an amp for jazz and I found it: I have tested lots of much more expensive amps (Fender Hotrod, Mesa F30 and MarkIV, Peavey Classic 30 ... tube amps, as you have surely noticed) and this one is really the best compromise given its price. You only need to add a quality distortion to it (a tubes distortion if possible) and you have a perfect setup...
2x35-watt solid-state amp with standard connections
It's very easy to use! You only need to read what the controls say! lol!
The clean sound is perfect, it's almost like listening to an acoustic! lol! It's a standard! It's easy to start playing clean and forget about the distortion!
The distortion isn't the best! You can't change it much with the EQ, but it's nevertheless a nice distortion.
Jazzmen will certainly rejoice playing it.
Personally, I play rock and to play with distortion you only need a pedal!
It's way more powerful than I expected, it's surprising!
The mark I gave it is for the amp as a whole, but the clean sound deserves a 10!
I've had it for six months and I want to buy a Vox ad50vt, but I really like it for its power and clean sound...
It's old, but it's loud!
It's an awesome deal!
Very easy to use, intuitive. You get what you want quickly. No need for a manual.
Amp for rehearsals and small venues. It doesn't have too much power.
Superb, beautiful clean sound that respects the instrument, well-balanced tone. Nice chorus, good reverb. What a delight with a Telecaster!!!
On the other hand, consider a pedal for overdrives and other distortions because it wasn't conceived for that.
An amp turned into a myth for its clean sounds and chorus. SRV used a jazz chorus. It's a reliable amp, like most Roland products.
