Hello,
I’ve read where the pedal can run on either 9v or 12v. Some folks say run it on 12v and some say 9v. So, which is best? My power supply can do 9v660 or 12v500. I’m using the Hi5 Mod Cloks.

Either option is fine and the pedal will perform the same, neither choice is better. Make sure you are using a center positive connector.
