Title: Weird power issue
Post by: irmcdermott on May 02, 2010, 05:39:57 AM
Haven't had this happen before and not sure what to check. My pedal runs off of a battery no problem, but if I plug a power supply into it powers down. Not sure what is going on. Thoughts? Thanks!

you prob. have your tip and ring of the power jack wired backwards (battery is on the lug that should be going to board +9v, and visa versa)
