PSM-5 Power Supply & Master Switch
Power supply and master switch from 1983. Routes power and signal in one utility unit.
The PSM-5 Power Supply & Master Switch combines a programmable signal router with a power supply output in a compact pedal format. It routes your signal between different effects paths based on footswitch control.
The master switch function routes the guitar signal between different outputs based on the footswitch state, enabling A/B switching between amp channels, effects paths, or other routing configurations. The power supply output provides 9V to other pedals.
Switch routing and level controls. Compact format with a single footswitch. The combined power supply and routing functions make it a pedalboard utility tool.
An early Boss utility pedal that combined two necessary functions. The routing capability predated the more sophisticated LS-2 and ES-series switching systems.
