All user reviews of 4/5 for the Roland Jazz Chorus JC-120

I bought this unit at Guitar Center for about $650 US

Great sound, great speakers, great chorus effect. Sparkling as any Fender Amp.

Some very cheap construction features. The input jacks (4 of them, two channels High and Low inputs) were plastic junk soldered to a circuit board with two resistors with a plug to the rest of the circuit. The plug idea is very good, but the plastic jacks fell apart after 2 months of careful use!

I replaced each with metal ones which I soldered to the board and they are fine now. The cost of the new jacks was 6 dollars and a little work.

Now I am extremely disappointed that Roland didnt have enough sense to put in metal jacks for 6 frigging dollars! I would have gladly paid 6 dollars more for the amp!

This kind of cheapened construction in an otherwise fine instrument is a real turn off.

What do I have to do, every time I buy one of their products, change the jacks? Lucky for me I am an electrical engineer and knew what the hell to do! For anyone else it would have been a hundred dollar repair bill.

I understand that I could have, under warranty sent the unit back and they probably would have repaired it - with the same plastic crap that broke in the first place.

Smarten up Roland! People shell out good money and you ruin an excellent instrument by saving a few cents on the part that takes the most wear on the thing.



See above comment on what I dont like about the unit. Otherwise it is fine.

Great instrument, with major stupid flaws that are quite preventable with common sense!

* Legendary “clean” amp with two separate 60 watt RMS power amps (to allow for true stereo chorus)

* Classic silver-cone speakers for vintage Roland Jazz Chorus sound

* Two input channels (Normal/Effect)

* Three-band EQ per channel

* One high and one low input per channel

* Reverb, distortion, adjustable vibrato and true stereo chorus

* Stereo effects loop


This is a clean solidstate amp with 2 channels, one of which you can add distortion to that's onboard.
* Footswitch jacks control chorus, reverb, distortion

UTILIZATION

Quite simple, all the controls are clearly labelled, and considering its a clean amp, there isn't much to tweak most of the time compared to distortion.

The chorus is one of the most amazing sounds I've ever heard. True stereo chorus within one amp is hard to come by and this amp has become legendary for that reason alone. The vibrato effect is also quite cool as well.

It's very easy to get a good sounding clean with this amp, even with all the EQ knobs at noon, it sounds great!

SOUNDS

The jazz chorus is known for great cleans. It has been around for at least 30 years for being known as such and has been used by almost everybody at one point in time. I of course, used it for strictly cleans for my good ol' numetal phase and metallica phase when I was totally into Wes Borland's clean sounds as well as Hetfield's live clean tones. I couldn't believe the sound I was hearing, it was an electric guitar with these very high quality woody sounding, almost acoustic-esque cleans.

It almost always dazzled me, the clean sound from this amp along with the very thick and shimmery chorus was always the clean sound I'd imagine a clean sound to be!

There is one thing that lacks of course, and that is the distortion. It is nearly impossible to get any good distortion sounds from the onboard distortion it purely there as an afterthought, to add a bit of clipping and slight dirt at most and almost never sounds good. You would need a distortion pedal, and even then you would need to find the RIGHT distortion pedal as the speakers in the jazz chorus are especially made for that awesome clean tone and not distortion. So most pedals plugged in would sound really harsh, sterile and super fizzy.

I have once plugged in my tube preamp morr-tone pedal through it and was somehow able to get a very usable sound. I was pleasantly surprised at the abilities of this pedal, the fact that I can plug it into such an amp and still get a very smooth and usable distortion is GREAT!

OVERALL OPINION

Overall, legendary for cleans and very nice chorus. Of course the chorus is adjustable on the amp but not for live purposes. But this amp is well known for a reason, that is providing great clean tones! Yes it is warm, but it is bright as well and has an almost acoustic-like character which some players may define as sterile and tinny. Though I find this amp to be quite usable, clean and bright and the acoustic quality is definitely a bonus!!

The JC120 is also VERY loud with more than enough headroom anybody will EVER need. You won't need to hook this up to another cab. Trust me.
