Well like everyone else:
100W transistors, clean and crunch channel, 2 Overdrives, equalizer (low, medium, high), Reverb, Effects (Chorus, Flanger, Delay and Chorus + Delay)
As against the little note I will add is the fact that there is a volume control speaker indepandant to that of the gain. ie that you can plug the headphones at the same time and have the sound on the amp (or not if you put the volume 0).
This is very effective to record with a sound card while having the sound on the amp!
The footshitch does not disable the reverb (but no worse)

UTILIZATION

Very simple, large buttons as a turn!
For overdrive, setting volume gain + is very useful and allows a great diversity of sound.
Just as the qd footshitch branch passage is clear channel / Overdrive can be done with the footshitch. Which is fine but ...

SOUNDS

Very versatile thanks to the diversity of settings.
I play a BC Rich and the clean channel is very sweet and crunch channel is very ... "Crunch".
As for the overdrive settings allow all settings, the shrill sound saturation light and warm a little bluesy, until the very saturated fat "contained"!
Powerful enough to play in a band with drums and everything!
For between her, when I plug in a microphone or piano I find her a bit and slammed shut but it's only my opinion ...

OVERALL OPINION

I use it for a year!
Ideal on stage, repeating, in the studio and at home!
An exellent sound and a great diversity of settings.
Affordable (in the 400E I think), a ttres good value quality price!
