This is an amazing fuzz!
MILLIE FUZZ IS A FUZZ FACE & BIG MUFF HYBRID
CRUNCH CHANNEL (LEFT LED OFF)
This is a heavily modified FF fed into a buffer and EQ borrowed from BM, offering a familiar classic silicon fuzz (BC108) tone with all the flexibility you need to shape your ideal tone.
BURN CHANNEL (LEFT LED ON)
This adds an extra BM gain stage to stack with FF and creates a more saturated, aggressive, and edgy fuzz.
There are 2 internal trimpots, the one on the left controls BURN channel gain bias and the other on the right controls overall mid response. You can make the BURN channel more tamed (clockwise) or more aggressive (counterclockwise), and both channel fat (clockwise) or scooped (counterclockwise)
Try 4.5V or dying battery for smooth, warm, more interesting clipping texture
Left foot switch is channel switcher. LED off = Crunch, LED on = Burn
Right foot switch bypasses all effects (fuzz and clean). Effective on both channels.
Internal trimpot (Left) is effective only on Burn channel
Internal trimpot (Right) is effective on both channels
