From the post
Info about the original:
ALL HAIL THE COLOSSUS!!! Unleashed on an unsuspecting public, the Colossus is THE be all end all Russian/Civil War Muff style fuzz. Ridiculously tweakable, insanely versatile, and packed with 10 tons of Colossal Mojo. Rich harmonic drenched chords, sweet singing leads, sludgy stoner goodness, filthy bluesy mcnasties, Pumpkin flavored raunch…you name it, it does it. It features a 3 way toggle for different EQ voicings, as well as a full range “Mids” control to help you cut through the mix in a live setting.
Edit: Corrected 2 values. the 2.2nF cap in the tonestack (column k/rows f-h) should be 22nF, and the 5.6nF cap (column b/rows h-l) should be 56nF. This should fix some of the issues with the tone and output of the effect that has been reported.
