Hey Crew,

I was at my buddies house checking out his triple rec. He showed me that his presence knob is working backwards. Go one way (up) and the effect goes down, the other way, well you know. It works but is backwards.....Weird :dunno:

If anyone can tell me why this is happening and how to correct this would be appreciated. He did have the 1st and 3rd preamp tubes changed recently. Thanks in advance.
