From the post

Happy Fuzz Friday! Been meaning to redo this one for a while with board mounted pots. A buddy of mine was reminiscing about a Sunface he used to own and wish he still had, so I built this with some OC71s for his 40th b-day. AnalogMan has used loads of different transistors in these over the years, both germanium and silicon, so socket and experiment. Easy fit in a 1590B.
