Analog distortion, classic case of at MXR if not brilliant color!
3 knobs: 1 volume, 1 level gain and 1 tone. Over-MOST-stamped a small push button "Crunch".

UTILIZATION

Many settings, opportunities really interesting but easy to use.

SOUND QUALITY

Used Gibson Les Paul and Fender Stratocaster.

OVERALL OPINION

I love everything about this pedal. It is a rare versatility and offers a range of rich and varied sounds.
Although this is not a pedal "high gain", the Custom Badass has a sacred headroom switch "Crunch" acts as a booster not volume but rather in the style of a "more drive".
Everything is very subtle and soft on the pedal, whether setting the tone or the distortion. In addition, it responds very well to volume control on the guitar. This provides a large variety of sound and really usable.
It blends perfectly with his sister, the "Custom Badass Mofified OD", which considerably broadens the possibilities.
Only, it offers plenty of sustain without the need to push the level of distortion.
Finally, she excels in rhythmic maintaining intelligibility and coherence.
A distortion of the very best for a very good price.
