Two Identical Heavily Modified Tubes Screamer pedals. making this pair for a metal band, guitarist and bassist. so tried to make the Mods applicable to both instruments. Increased gain for more drive/distortion and Features a number of clipping options. Silicon, LED, MOSFET, and combinations. giving a total of 6 different distortion characteristics.
So as I’m sure some of you can tell this pedal layout and design is based on the Earthquaker Devices Palisades guitar pedal. the Palisades is actually a highly modified Tube screamer 808. This is not a clone of the Palisades. This is a Big Muff. This is the big muff to replace all big muffs. It is designed to be able to do pretty much anything any variation of a big muff can do plus a lot more.
The 12-position Width control is similar to the “Bandwidth” control on the palisades, It changes the low end response at the input of the pedal, this heavily effects the distortion character. more bass, more fuzz.
The Voice control is a 6 Position rotary that changes the diodes in the two clipping stages simultaneously. 1-Mosfet. 2- Silicon and Germanium. 3- L.E.Ds. 4- L.E.Ds and silicon. 5- L.E.Ds and Mosfets. 6- No diodes. these options I found gave a wide tonal variations and each added something a different.
The switch GI/SI. changes between either silicon or Germanium Transistor as the two clipping stages. one big muff variation that uses germanium transistors is the Hoof Fuzz. The Silicons have a lot more gain and a harsher sound.
The Boost control puts an extra Mosfet gain stage between the two clipping stages to drive harder into the second. The Left most footswitch bypasses this boost stage and the second clipping stage. A Big Muff with only one clipping stage cleans up really nicely and can be used as a boost with a bit of subtle clipping.
The Tone control is a little different, but you can still achieve the classic scooped mids of the original big muff with the curve control. the whole tone circuit is bypassed with the footswitch in the middle, taking this out gives a noticeable boost in volume and also overdrive the output buffer a little bit. The right footswitch is a true bypass.
