Pre Loved BOSS PSM-5 Power Supply & Master Switch

Power supply for multiple pedals

• Takes a single 9V adapter input
• Distributes power to several pedals via a daisy chain (typically up to around 7)
• Designed before modern isolated power supplies were common

Master effects loop switch

• Includes SEND and RETURN jacks to create an effects loop
• Footswitch toggles:
  • ON: signal runs through all pedals in the loop
  • OFF: signal bypasses them entirely

This allows you to turn multiple pedals on or off with one press.

Signal buffering

• Uses buffered bypass
• Helps preserve signal strength across longer cable runs
