Okay so for the technical description see the review below ...

technqiuement super stuff considering the size of the craft and take in what they do!

UTILIZATION

General hyper simple config

SOUND QUALITY

The effects are very good, I use attention with good headphones (Beyer Dynamics DT770 pro ...) so I made a very correct crunches excellent resume that although the dynamics of a vox, nothing to do with sound of my marshall (level tone color)

So the interest in this lil contraption is being able to repeat that painful, not only can play with headphones standing (without tie)
but what really helps is to connect an input auxieliere with a backing track ... and there is happiness (cd or mp3 player)
and we play on his favorite track without sweat around her.
great tool that takes little space and trèssssssssss really quick plug (avoid leaving an amp to turn a bunch of stuff) ...
we become lazy with age ...

great for short work

his side, I am so excited that I plan to plug into a console one of those 4!

I tested the AC 30 (the others are more oriented saturated exclusive)

its clear (nice fights)
its crunch is where he takes his interest I think even if I took the AC 15 for its clear if needed.

OVERALL OPINION

I use it for a few weeks

value for money nickel

Least uh ... autonomy?? although I have not worn my batteries ...

yes I do it again this election Michael!
