- Knob 3 - "Tone": This knob is a treble-bleed style tone control. Full clockwise is full treble. Turn counter-clockwise to remove highs from the signal.

Phase Inversion
From our examination of the schematic below, the 855 Drive appears to not invert phase on the output as compared with the signal that goes into the pedal.
| Electronic Part | Action | Phase State |
|---|---|---|
| Q1 | Does not Invert | Buffered-in Original Phase |
| IC1a | Inverts | Inverted |
| IC1b | Inverts | Reverted |
| Q2 | Does not Invert | Buffered-Out Reverted Phase |
This conclusion will need to be born out by testing and observation.
Pedal Manual
As of this time, BYOC has not issued a separate manual on how to use the pedal. The best reference is either this wiki page, or the instruction manual at Buildyourownclone.com which describes the architecture of, and how to build the pedal.
