Exar OD-01 Overdrive

 These things is getting really expensive especially since it got hyped by JHS and was included as the "XR" mode in their Bonsai pedal. It is basically a YATS/Boss-OD-1 with some value changes here and there and assymetrical soft clipping.

Schematic is avaiable HERE.

  1. I looked up this transistor - it was a new one for me. Says it's around 180 hfe. I guess some 2n2222, or low value 2n3904s might be a good substitute?

    1. The transistors are wired as unity gain buffers so part number and Hfe isn't important, really. You will be fine with some jellybean 2N3904s...
