From the post
Happy Fuzz Friday! Revisiting one of the early layouts of the blog–John Lyon's Scarab Deluxe. Been meaning to draw it up with board mounted pots for a while. Ian Nelson sent me his version and with a little modification we can check that off the bucket list. Great sounding fuzz based on MicTester's Hot Silicon.
