From the post
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.
