Hey guys, so I'm about to put a road rage into my jmk op amp big muff and was just wondering.... If I connect the power supply jack into the positive 9v pad and ground pad next to it like it does in the wiring diagram of the road rage, where does the -9v wire go to? (board I assume?) Also, on the JMK op amp board, the 9v pad says +9v. This is why I'm a little confused. I hope I didn't confuse any of you guys with this explanation.
