It is a booster which has an analog input & output jack 6.35 plus a 9 volt power supply

UTILIZATION

Could not be easier
one button to refreeze the nivau boost desire

SOUND QUALITY

Superb, too loud, perfect is the total
I think it's really the booster REFERENCE
I use it with a Stratocaster or a Gibson is your exact the same.

It lgrement crunch when you put a substance if it is really perfect!

OVERALL OPINION

I use it for 1 year did nothing wrong
