supply

A power supply for pedals is a device that provides stable, isolated electrical power to multiple effects pedals at once. Instead of using individual batteries or wall adapters, a good power supply ensures each pedal gets the correct voltage and current, reducing noise and hum.

Many pedal power supplies come with multiple outputs—some isolated to prevent ground loops—and can handle different voltage requirements (like 9V, 12V, or even 18V). Using a reliable power supply keeps your pedalboard neat, efficient, and your tone clean and consistent during rehearsals and gigs.
