L'avis de rouldug"Ampli exceptionnel pour le jazz et pour le folk "

Roland Jazz Chorus JC-120
Amateur de son rock, le préampli manque de patate et vous aurez un son compressé, mou, sans grande dynamique. Mais pour le répertoire folk et jazz, vous aurez LE son, à la fois clair, clean, riche et plein. Dans le genre, il reste le meilleur. Les Yamaha à transistor récents, ceux dont se sert John Scofield, le talonnent de près. Si vous vous voulez un son plus chaud, prenez un Fender Twin Reverb mais il faudra le régler astucieusement.

Roland Jazz Chorus JC-120
Je possede cet ampli depuis 8 ans et rien a redire. Un son clair et precis, adapté pour le jazz. Je ne trouve pas d'inconvenient technique.
Seuls le poids et l'encombrement me rends les deplacements un peu "ch...ts".
Cet ampli à la patate, je ne le preconise pas a ceux qui vivent en appartement avec des murs de 5cm d'epaisseur!

L'avis de -Livingroom-"Sons clairs magnifiques."

Roland Jazz Chorus JC-120
Je m'en sers en studio, pour les sons clairs évidemment, mais aussi sur une basse, à faible volume, pour rajouter une attaque intéressante.

Bien sur il est tout à fait utilisable sur scène, ce n'est pas le plus léger des amplis mais... Y a pire ;) Ça reste une référence, et avec raison, d'autant plus que l'avantage d'un ampli à transitors est sa résistance, c'est du costaud!

Les sons cleans sont magnifiques, ainsi que le chorus intégré (comme Roland sait les faire). En revanche pour les sons saturés, on repassera, ou on lui adjoindra une pédale d'effet dédiée. Les réglages sont fins et efficaces.

J'aime ses sons clairs, et le tarif encore abordable pour un ampli vintage :) En revanche la disto intégrée est dégueulasse, dommage :)

- 2 entrées par canal (LOW / HIGH)
- Boucle d'effets stéréo, sortie ligne stéréo, 3 prises pour footswith (Disto - on / off, chorus-vibrato on / off, reverb on / off)

UTILISATION

- Configuration très simple et intuitive
- Contrôles fonctionnels et ergonomiques
- Manuel clair et suffisant
- On obtient très facilement un bon son

SONORITÉS

Dépasse largement mes attentes.
Le son clair est magnifique, la reverb également (Etendue et musicale), le chorus stéréo et le vibrato sont de toute beauté.
La distortion est sèche est moche, quelque soit le degré de réglage.
J'utilise cet ampli avec mon Rhodes et mon Blofeld simultanément.
Le son du Rhodes est merveilleux, les basses sont bien présentes, punchy et ne brouillant pas le son global, les aigus cristallins. Les effets fournis par l'ampli sont tout à fait pertinents pour ce type d'instrument.
Je ne me sers pas de la distortion.

AVIS GLOBAL

Je l'utilise depuis quelques années.
J'ai hésité avec d'autres amplis, que j'ai pu tester préalablement (Fender Twin reverb, Deluxe reverb, Roland KC-XXX). Le JC-120 gagne haut la main à mon avis. Ses avantages : 2 canaux, permettant d'utiliser Synthé et Rhodes en même temps, effets calibrés pour le Rhodes, grande étendue de rendu sonore, permettant d'utiliser un clavier là ou la plupart des amplis gratte chutent dans les graves.
Prix intéressant, bonne puissance, bon look, solidité apparente de l'engin, boucle d'effets.
J'ai hésité avec le Twin reverb, qui a une excellente réputation (Ampli de test des Rhodes en usine, full tube...)
Au volume ou je l'utilise (Appartement bien isolé) il surpasse largement le Twin à mon avis. Le rendu est bien meilleur dans les graves, et en plus il est moins cher (Sans compter l'économie de changement de lampes)
Les petits bémols sont son poids, conséquent pour un ampli à transistors, un léger souffle, et des basses quelques peu en retrait.

Roland Jazz Chorus JC-120
* 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.

Roland Jazz Chorus JC-120
Probably the most recognizable Roland amp ever created. Also probably the most highly sought after solid state amp on the planet. And maybe the most highly used clean tone that has ever been created!

From studios to stages this amp has seen a number of uses and major users, such as Metallica and many others. This amp has a clean tone that is perfect for recording as well as running a pedals in front of.

SOUNDS

The tone from this amp is so legendary! The clean is really the reason you buy this amp but the ability to take distortion pedals is a huge bonus. The amp takes on your favorite pedal quite well and amplifies the natural harmonics of your guitar and playing style.

For me there is only one reason to own this amp...and that is to use it on a recording for clean tone. The chorus is very lush and smooth! It sounds great with just about any guitar you throw at it. If you have listened to any Metallica album then you have heard this amp.

OVERALL OPINION

I would recommend this amp to anyone who needs the best clean tone you could get out of an amp. I am partial to solid state cleans as I feel that they have a sparkle that tubes cannot match. Distortion is a whole different ball game but the cleans will get you the best chimey sparkle you have ever heard.

At new these amps come in at around $1200. A little bit on the high side for a solid state amps. IF you really want to gig with this amp then it is a good purchase, but if you just want to use it for recording a particularly the clean then save several hundred dollars and get a Cube amp from Roland that has the JC Clean. But this amp is so classic anyway that it is a must own!
