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!
