Boss Power Supply & Master Switch PSM-5

More images:

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!

  • I use this only as a bypass switch (it didn't come with the daisychain anyhow!), and it's a great pedal to have if you can find it cheaply. Otherwise, DIY (assuming the looper *and* power supply together aren't why you want this). Loopers are a cinch to build (if I can do it, anyone can)!
  • Good Points: It does what it's supposed to! Great for bypassing multi-effects that might negatively affect your signal in bypass. Also great for non-foot-switchable pedals (voice-changers that haven't been re-housed, for instance). ...I kinda think it looks cool...
  • Bad Points: Occasionally, I've noticed a tiny bit of signal bleed-through with really hot signals, but this has not been a real problem... I have noticed this even with DIY loopers that use nice switches. They seem to be becoming "collector's items", meaning sellers will sometimes hike up the prices... ...I paid more than I should have...

  • this pedal is great as it can supply power to multiple pedals without needing a wall wart or battery for each. it is also a master switch for an effect chain. the only thing i find annoying is that it needs a cable plugged into it to supply power to other pedals, so it can't be used just as a power supply. easily overcome by plugging in a spare cable.
  • Good Points: can power up to 7 pedals. can be used as an on/off for an effect chain. has input/output + effects send/return
  • Bad Points: can't be used solely as a power supply, but it's no big problem, just a little annoying.

  • Pedal works great for those that use multiple effect units, or other 9 volt powered gear. For the cost of a couple wall warts, you can buy the psm-5 freeing up outlet space and gain a master on/off switch. Like many boss products the pedal is constructed of steel, and can take a lot of abuse. Ive had boss pedals attacked with grinders, showered with sparks from a welder, dropped, kicked, thrown,etc and other then cosmetic damage they all still work as well as they ever did.
  • Good Points: powers up to 7 other pedals can be used for an effect loop
  • Bad Points: none
