Power
What power pedals do to the signal, where the chain planner places them, and what to read next.
A power supply is the one device in this whole taxonomy that never joins the audio signal path at all: it exists to power every other pedal on the board, not to process the sound passing through them. It has no place in a signal-chain plan for exactly that reason — planning what it powers, and how, is a completely separate question from planning what order the signal passes through the other pedals in.
The types in this family
- Power supply (rank — not in the chain): A power supply is not in the audio path at all. Plan it with the power planner (pedal-power-planner.js), not with this one.
Where it sits in the chain, and why
Because a power supply carries no audio, the chain planner on this site correctly refuses to place it anywhere in a signal-chain plan — it is not early, late, or anywhere in between, because "in between" only means something for a device the signal actually passes through. The right tool for a power supply is the power planner on this site, which answers the real question a power supply raises: which of its outputs can power which pedal, given each pedal’s voltage, polarity, current draw and isolation needs, and what is left over or left unpowered.
Power notes
A power supply’s own specification is the one in this whole taxonomy that matters most directly: its per-output voltage, current rating and isolation determine what it can and cannot power, and those figures are exactly what the power planner needs as input to produce an honest plan. Where a supply’s own documentation does not state a given output’s rating, that output simply cannot be planned against — an unstated rating is never assumed, on this site’s planner or in the guidance here.
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.
Every rank and reason above is quoted straight from pedal-chain-planner.js's PEDAL_TYPES — the same taxonomy this site's chain planner runs and docs/gearwarrior-pedals-contract.md documents. No second table.
