SuprFuzz is a derivate of the classic Univox Superfuzz. This is a prototype. It has the standard “Fuzz” and “Volume” controls (“Expander” and “Balance” respectively on the original Superfuzz), and also a “Tone” control that adjusts the amount of midrange scoop (instead of the “Tone” switch on the original, which disables of the filtering). I also added a switch the change between the original germanium clipping diodes, silicon diodes, and no diodes at all. A switch to change the midrange scoop frequency is also added, you can switch between the original Superfuzz filtering, and the filtering used in the Ibanez Wau Fuzz, another derivate.
