Pitch

Pitch-shifting and octave pedals generate a new pitch — up, down, or both — from what is actually played, either blending it with the dry signal or replacing it outright. Getting this right depends on the pedal tracking the fundamental pitch accurately in real time, which is a harder signal-processing problem than almost anything else on a board, and it is the reason this family cares more than most about what signal it is fed.

The types in this family

• Pitch shifter / octave (rank 50): Pitch tracking is most accurate on a clean, undistorted signal; the shifted note then runs through the gain stages like any other.

Where it sits in the chain, and why

Pitch tracking is most reliable on a clean, undistorted signal, so a pitch-shifter or octave pedal sits ahead of the gain stages — fed the guitar’s own note rather than an already-clipped one, its tracking algorithm has a clear fundamental to lock onto. The shifted note it produces then runs through whatever drive, modulation or time-based effects follow, exactly like any other signal reaching that point in the chain. Feeding one of these pedals a distorted signal is a common way to get unreliable, glitchy tracking, not a stylistic choice most players make on purpose.

Power notes

Pitch-shifting is computationally demanding compared with a simple analog effect, and many pedals in this family run on digital signal processing rather than analog circuitry. That tends to mean a higher current draw and, often, a preference for a clean, isolated power source rather than a shared daisy chain — digital circuits are more sensitive to the noise a shared ground can introduce. Confirm this against the specific pedal rather than assuming it.

General guidance for the family, never a specification for any individual pedal — always confirm voltage, polarity, current draw and isolation from the maker’s own documentation before wiring a real board.
