Used Boss PSM5

Boss PSM-5 Power Supply & Master Switch Pedal

“Vintage, Functional, and Collectible”

Dual-Purpose Pedal for Power Distribution and Signal Routing

The Boss PSM-5 is a vintage utility pedal that combines a power supply and master switch in one compact unit. Released in the early 1980s, it was Boss’s first dedicated power solution, capable of powering up to seven 9V effects pedals via its daisy-chain output. But it’s more than just a power hub—it also functions as a loop switch, allowing players to engage or bypass an entire effects chain with a single stomp.

Housed in the classic red Boss chassis, the PSM-5 is a piece of pedalboard history. Though discontinued, it remains a favorite among collectors and players who appreciate its simplicity, reliability, and vintage charm.
