Master switch for one or more other effects
The Boss Power Supply & Master Switch PSM-5 has two main functions.
First, it can serve as a master switch for any other pedals in the SEND/RETURN loop.
Engage the switch and audio is routed through the loop. When it's off, the pedals in the loop are bypassed.
Second, this pedal can serve as a power distributor for up to 7 (or more) pedals. Plug a power adapter into the 9V IN and connect a daisy chain cable to the out to power other pedals.
The PSM-5 could be used to quickly introduce an effect or effects into a signal for sudden blasts of noise!
This particular Boss Power Supply & Master Switch PSM-5 has some scratches and paint
chips. Includes a used non-Boss 120VAC to 9-volt DC 300mA power adapter plus a brand
new Visual Sound 1 SPOT Multi-Plug 5 cable MC5 (allowing you to connect up to 5 units
to one cable --- a $9.95 value).
