It is a small box that plugs directly to the guitar, it is powered by two AAA batteries (included) with an AUX input and headphone output.
The case is about 40g and is smaller than a tuner.
3 controls: Gain, Tone and Volume.

UTILIZATION

The use could not be simpler: you plug, turn the knobs, the sound is refined and you can play.

SOUND QUALITY

The sound is stunning, used with my Washburn Dimebag Darrell We2 st (Sh-13).
The distortion is just huge! it's heavy, accurate.
It is very similar sound Pantera, Metallica, Trivium ...
No breath, this amazing little box.

MY VIEW THAT MAY BE HELPFUL HINT

OVERALL OPINION

I offered a friend (think about it, that's great as a gift).
The characteristic I like most is the fact that you can play metal with good sound quality anywhere.
I had not tried to Pod or V-amp before but I was really amazed.
The value is good.
Surely the choice I would do if I had to use it.
