UTILIZATION

The configuration is it simple?

Yes very simple! To clean but mostly thanks to distortion (or cause) of the 4 predefined sounds.
The manual is clear and sufficient? ...

I do not remember having had a manual, but t'facon not need!

SOUNDS

Well I tell you I really do not AIM this amp.
The sound is bad in general, see very very ugly! The four predefined sound virtually limited to these four amp sounds since the equalization is almost enexistante.
The overdrive is not too bad for an amp to price, the distortion lacks punch and attack not really .. For the metal, bof ^ ^. The canal is really a metal stack banish the sound is very cold! I really feel to hear a gressill tl ..
The big point is the possitive clean, I find really successful. Once the equalization faois being very nearly useless, it will jou with the regulation of the guitar.
If there was an effects loop I would not be made a score above 3 is stupid!
