Well it is a straight forward set up with bass, mids, and treble with presence. The usual gain and volume. It has nice boost that you can use on gain or volume or both.
The general tone is chunky rough and aggressive.
This thing has punch and balz ...big time!!!
It has a couple of switches inside to move the OD up into even more gain.
A little pricey but with a far from average set of features and a track record for quality.
