DESTRIER is the ultimate 70's style fuzz device, named after the ultimate warhorse with good reason. If you want skull-crushing fuzz, this is the ONE. Actually it does extremely well with lower gain settings if you prefer boosting techniques rather than a heavy wall of fuzz.
Old school 4x transistor design brought forth into an analog future. Extremely versatile sound shaping via the array of toggle switches. You can scoop/boost the mids (both modes sound awesome), and cut/boost low frequencies for heavy woolly mammoth type fuzz.
You can also use it as a nasty octave fuzz, or even just as an analog octave generator (by turning the OCTAVE switch on and fuzz knob down) to stack into other distortions and fuzzes!
