The Digitech Whammy IV comes with an included power supply. I've been using that power supply and it works fine, it's just a pain to use when I can power the rest of my pedals from my board. Do I have to use the adapter that came with the Whammy or can I plug it into my pedalboard's power?
As long as it has the same volts and amps going to the pedal Like 9 volts @ 250 mA or whatever your pedals original supply is at
You have to use the whammy adapter because it is AC not DC. Also it is not a standard 9 volt power supply its more like 9.6V. And most likely your other power supplys won't fit into the whammys. Because it has a bigger center post than a standard adapter. Sorry brah.
