Re: JC-120 chorus without the JC-120?
Having had a JC, a ce 2 and a ce 3 i reckon i can help out.
Definitely not the Ce3 - modded or un modded it is just less thick and lush. MOre hi fi tho if you mod it.
Ce2 is better - thicker and warmer. Nice.
Personally, i dont like thge sound of the jc amp, but i do have to admit that both the chorus and the reverbs on them are lush. Actually, i reckon the chorus sound on the amp is maybe my favourite chourus tone.
A modern pedal that should get you there is the voodoo labs analog chorus. Its a clone of the ce1 but with true bypass. Failing that...the MXR big yellow chorus thing can do huge and lush warm swirly stuff and keep your bottom end intact. Actually, i reckon that one is a good option - prolly better than the JC's built in chorus.
