From the vendor
Nick Greer's overdrive, formerly built by Greer Amplification for endorsers only. It is an Electra Distortion: one 2N3904 stage with collector-to-base feedback bias, followed by a pair of 1N4148 clipping diodes to ground, with a 25k Clean Mix pot added in series with the diodes to raise the clipping threshold so more clean signal comes through.
