There are three possible distos diffrent on the pedals, a volume gain knob.

UTILIZATION

Too simple to use!

SOUND QUALITY

The disto lgre (limit indicernable) in its most fat exists, you can do anything!

OVERALL OPINION

I play on this for over two years and is the best of the best distortion issue "that changes a little BOSS" ... I advise all bass players largely dsireux overdrivesques of experiments.
