A super cool MXR Distortion II from way back when. When what? When pedals were held together with 8 big old screws and had their own 120v cables, that's when. This one had sat dormant for a while. The transformer's connection to ground had come loose and the two diodes in the power supply had died. Surprisingly, the main filter cap was still a-okay. Once resurrected, we were treated to a flavor of grit and drive that we'd forgotten about. Not quite a Muff. Not really a Rat. And not a Tube Screamer either. These have a unique sound that's all their own. The Resonance knob should really be relabeled "meat" or "gravy" or maybe just some sort of grunting sound with quotes around it. Turning it up slathers on a thick layer of beefy bottom end that makes me wonder how it would sound on bass.
