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.
