Impossible Colors - Transformer Coupled Fuzz
Impossible Colors is the ultimate fuzz for me and what I was looking for when designing it. I wanted a single pedal that could cover dirt tones ranging from overdrive through distortion and on into totally compressed splattery fuzz that has hints of octave, ghost tones, and surprisingly accurate horn emulation. There is dynamic analog dirt in the in-between tones and, for the adventurous, absolute delight in the extremes. Finally, I wanted a fuzz that was agnostic about placement before or after buffers while still having massive dynamic range and texture, so I included a transformer-coupled input stage that emulates both single coil and humbucker pickups to give the user maximum flexibility when incorporating Impossible Colors into their rig. Let's take a look at the controls: Note - Some combinations of settings may cause oscillation. Raising the Attack control setting will usually retain the sound you had while cutting off the oscillation. Or maybe you like the oscillation. Do you! Impossible Colors is unique among BSRI Audio products in using vintage transistors to achieve its complex blend of tones. When I was working on this circuit I spent months sorting through everything I have in my shop and seeking out just the right parts sourced from around the world to make it sound exactly how I wanted. The parts aren't 'magic' or anything like that. They're just tested and selected for each unit to do exactly what they're supposed to do. It takes a little extra time, but for this circuit, it's worth the effort.
