*Note: Walrus Audio has switched to stating a minimum power supply capacity, rather than actual current draw figures. Thus, the actual current draw figure may be smaller, but we don’t know by how much. What those figures do indicate, though, is which output (nominally 100 or 300 mA) to use on our power supply, for safe operation.

A few pedals in this list has specific ”9vDC only” notes, due to onboard voltage boosters being present. That note is there as a courtesy warning that going above 9 volts will most likely cause damage. However, Walrus Audio does not recommend trying any of their pedals with anything other than 9vDC.

Incidentally, they also recommend using a separate/isolated power source for all of their pedals. And for the Luminary, they specifically mention that it will not work with Strymon power supplies.
