The Bearded Lady Overdrive by Freakshow Amplification is based on the early version 1 thru 3 Fulltone OCD Overdrive/Distortion pedal. But with added options for a wider range of tone!
TUNEABLE OPTIONS
*Internal dipswitch to change the tone capacitor from V1 to V2/3.
*Switch added to change the first gain stage structure a bit as some of the aftermarket pedal modders were doing to the OCD pedals.
 
From the builder:  "The changes are subtle but do offer a bit of tone tuning that originals did not. As for the chip, I chose NE5532 for the simple reason that I liked the clarity/tone of it the best."
