To understand the schematic, you first have to understand where the pedal came from. The Ultimate Octave is a refined evolution of the vintage Foxx Tone Machine. Mike Fuller took that classic 1970s circuit and added modern reliability, a more versatile EQ, and a "Fat/Bright" switch that dramatically changes the pedal's character.
