I recently purchased a floorboard to go with my pre-FBV Pod 2.0. After I play on it for a few minutes it effectively mutes the Pod. No sound comes out of it until I select a channel. When this happens the display on the floorboard shows 0, the display on the Pod goes blank, and the Manual button on the Pod lights up. It doesn't do this immediately after I've touched the floorboard so I don't think I'm pressing the wrong button somewhere. It also fixes itself if I disconnect the floorboard. Any ideas of how to fix this?
