This pedal is a recreation of the famous "Elk Super Fuzz Sustainar" (thats not a typo, thats how they spelled it!) pedals from the 1970's. These pedals were very cheap Big Muff "Triangle" copies made by Elk Inc., however, they sounded almost nothing like any of the original EH Triangle knob pedals. The Elks were made with very unreliable components, cheap circuit boards, thin metal enclosures, were not true-bypass, and would break if you looked at them wrong. However, the carbon-comp resistors and ultra cheap caps added a noisy mojo that would increase as the pedals aged. Some components would drift as much as 50% of their stated values!
