Way Huge Drive/Geisha Drive

The Geisha Drive (or just called Drive sometimes) was a limited run overdrive from Way Huge and is a great sounding circuit. It uses a quad opamp to form an input buffer stage, gain stage, followed by some hard clipping and a modified BMP tone stack, into the volume pot, followed by a gain recovery stage. Should fit nicely in a 1590B with the pots board mounted.


  1. hi everybody!
    just finished the pcb version and it works great!
    i could,t get the jrc4741 chip, so i used some old behringer quad op-amps (BE037)
    witch are a simmilar to a LM348! so i think this should work with some lm,s too!!
    many thanks for another great layout ( it,s always a plesure to build some of your stuff)
    i think you can mark it as verified!!
    greetings from austria

    1. Thanks for verifying and thanks for the kind words!

  2. LM348 works great, Itried too TL074 but low gain fuzz.
