The Muff for people that don’t like Muffs, the Giygas features a highly modified fuzz engine that does the Muff thing without any of the bad stuff. Do you want volume-knob cleanup? Kay-O. The Giygas does that. Do you want a punchy tonal profile without the standard tone circuit messing everything up? Kay-O. The Giygas sculpts its tone with respect to the surrounding circuitry while avoiding the lossy dual-filter approach of the original.
