KMA Chief Disruptor

From the manufacturer:

The Chief Disruptor is a Fuzz/Distortion pedal, that offers a Muff-Style circuit with a lot of tweaks, such as 3 different gain modes, pre- or post switchable Mid-EQ and Clean blend, as well as active Bass and Treble controls, a footswitchable and expression controllable parametric Mid-EQ, plus a top boost for even more raspy grinding bite.
It is probably the most flexible Muff-Style pedal on the market!
