Almost ALL BOSS units made pre-1997 and some newer pedals; you really have to check with the pedal manufacturer.
The link below provides quite a bit of info, as does the Visual Sound 1-spot site. There is so much misinformation and misunderstanding of pedal power supplies, wall warts etc. it's alsmot an accident when a player with a multi-unit pedalboard doesn't have some sort of weird hum/hiss/wrong sound problem going on.

Basically there are 3 types of power for 90% of the so-called 9V-power effects pedals made...ever:
Unregulated (measuring 12-14 volts, often referred to in the pedal-maker world as ACA-type)
Regulated (aka Switching, aka "PSA - the BOSS designation) - measuring 9.6 volts unplugged, dropping to 9V plugged in.
Batteries - generally measuring 9-9.7 volts brand new and dropping to 9V or less immediately upon being snapped into a pedal and activated (try it sometime - measure one, install it, plug in an input cable, switch the pedal on for just a second or two and pull the battery, measuring again).
But - NEVER use 12 volt or 9 volt or ANY volt multi-voltage adapters or any of the Radio Shack, telephone charger or non-audio adapter unless you like tons of hiss and hum.
Now that an answer guessing at the reason for the question was given - what WAS the real reason? Because there are a whole bunch of specific uses and non-uses for certain adapters, and some pedals that use 12-volt adapters have to use only one specific type.

Thanks for the response, Jim. I guess the question isn't as straightforward as I had imagined.
I have a couple of battery-powered 12V portable amps that I'd like to use outboard effects with. I know I can fiddle around with 12V to 9V converters and use 9V pedals, but if there are 12V pedals available, they would be easier to integrate, yes? |
