From the post
Guyatone realeased some very interesting, innovative and good sounding circuits in the 80s. Since they are sadly overlooked and quite rare, Deadend Fx decided to trace and release PCBs for some of these gems. PS024 Distortion H shares some similarities with Boss HM2 but it still differs enough to not qualify as a clone. The most eye catching feature is the 5 band graphic eq at the end of the circuit with its dedicated graphic eq IC which can be found at Ebay and Alliexpress for quite cheap. Deadend Fx Hive build docs is avaiable HERE.
