The Big Fuzz is a muff circuit, which has been critically re-tuned to improve the tone, playability, and versatility of the pedal. This is a modern fuzz-distortion, with a big sound and higher gain and sustain than the classic Russian version muffs which I make.
The MIDS control knob sweeps from the classic scoop (all the way left), through to a more focused modern tone, with everything nice in the middle. This flattens out the effect of the hi-low TONE control knob.
The BMP/STB switch toggles between a modified muff setup, to a 1973 Colorsound Supa Tonebender style mode (with the variable mid knob, and an altered tone pot sweep). The STB mode has less diode compression on the low-end, widening the dynamic range in the bass, and allowing the natural transistor fuzz character to be better heard.
This fuzz uses gain-selected transistors, and original clipping diodes (different from those shown in gut shot). This is built in a small-footprint Hammond 1590BS enclosure. There is also a point-to-point "XXL" model available. The current cases have raw metal sides, not black powder coat as previously made.
