Artie..The Boss PSA 120 ASA 120 or the Ibanez adapters all work fine...As long as it's filtered..You already know all this but..."What the heck! :smack:
The filtering is something that is built within the power supply on the adapter you buy and it keeps your pedal from humming when you plug into the adapter and then into the wall...If you were to plug a non-filtered or (Non-buffered)power source into your pedal,you'd hear annoying hum...
