Boss PSM-5 Power Supply & Master Switch – Made in Japan (Vintage, 1980s)
I’m offering a Boss PSM-5 Power Supply & Master Switch, a vintage and now discontinued utility pedal made in Japan, designed as a central power and routing hub for classic Boss pedalboards.
The PSM-5 is not an effect pedal, but a master control and power distribution unit, allowing you to power multiple pedals from a single adapter and switch your entire pedalboard on or off with one footswitch. It also functions as a signal routing hub with Send / Return loop, making it a very practical piece of vintage Boss hardware.
This model was produced in Japan in the mid to late 1980s, during the high-quality Roland/Boss era. It is increasingly hard to find, especially in working condition.
