Small red metal boiboite 9v battery powered, so it's nice to report: autonomy seems limitless!
Connections: In, Out. (And 9v)

UTILIZATION

In use, of course, super simple, it turns knob. You know get the sound of your hi-fi? Yes? So you know how to use this thing ...
I bought it on the advice of a salesman (never do that! Just kidding) to give a little more than meets the saturation of a JCM900 with a telecaster. It fulfills this role very well.

SOUND QUALITY

The effect is very effective, the sound is significantly increased even before you push the knob thoroughly.
The small dedicated switch is used to simulate the sound of humbucker, I'm not thrilled with this system, but I have not purchased it. However, when not in use, I appreciate the transparency of the object.

OVERALL OPINION

I use it for more than two years, at least three hours a week, and I never changed the battery!?!
Price level, these little animals are rarely given, but given the appearance, it should last a long time, all metal, solid construction ... I think we will not have to buy often, and it is the cheapest I found when I discuss it ...

This little machine friendly and fits perfectly solid boost.
