Fjord Fuzz Berserk V1Verified
Based on the Fjord Fuzz Berserk V1
From the post
Another interesting Fjord Fuzz circuit traced by evilarsen. An old school silicon fuzz with a switch that toggles between Fuzz Face/Tonebender Mk. II modes. Also a thickness pot that is a input cap blend control. It may be worth having the internal bias trimmer as an external control...
