Jon Patton's Mossy Sloth
Based on the Jon Patton Mossy Sloth
From the post
Finishing out Jon Patton week with the Mossy Sloth Fuzz for Fuzz Friday. It's a pretty unique transistor-based fuzz and uses MOSFETs to create some asymmetrical clipping for some unusual fuzz and distortion sounds. Loads more info can be found here.

- Q5-8: the legend prints BC170 but the four parts are drawn with D/G/S pins, so BS170 may be meant
