Top solid state amp i ever have
First of all, i love the retro looking, the feel of the knob, everything looks so well made, the sound is amazing, clean and clear, loud enough to make a good live presentation, the chorus and vibrato is beatiful in so many ways, and if you have a stereo pedalboard you can exploit his full potential, have footswtich, have effect loop, deal very good with distortion pedal and overdrive, only bad thing it's kind of heavy to deal in live presentations and have a little floor noise that can be annoying but it's not the end of the world, love the reverb and the distortion it's not that bad.

nice cleans, handles pedals well
Does have a slight learning curve it also can get pretty loud. The built in reverb and distortion are both pretty good. Weighs like 40ish pounds. Great sub one thousand dollar solid state. I would recommend getting some sort of stand for it however as it is pretty heavy as previously stated. (used on “Not So Kino”)
L'ampli parfait pour les amoureux des pédales...
Son clean exceptionnel, il prend toutes les pédales de la meilleure des façons. Une usine à sculpter du son! <3

Crystal clean tone! Legendary Chorus!
The powerful little.brither of the JC-120! The JC-40 delivers clrystal.clear clean tones. The legendary on board Chorus! It is a perfect pedal platform. It is the feather in the cap of any amp fleet!

Crisp and lush
Has the rich presence of the JC 120 without the need for a forklift to tote it around. Not only does it recall the bright chorus sounds of 80s while providing a solid palette for your favourite jazz tones, but it offers a perfect, clean solid state foundation to build your pedalboard tone-house upon. Distortion is a bit limited but that is not why you bought this anyway.

A tiny JC-120
Packs a serious punch, especially when considering the size. Bought right before Gone Wild, and haven't looked back.

Best amp in the world!
I love this amp. Best chorus sound and light. Small but puts out enough sound for the concert venues we play without distorting.
