So when I change my channel volume it changes the effect knob next to it.  No blue lights show up and I have noticed effects turning on here or there.  Probably due to vibration but the other problem is what im trying to figure out. And also when i try and make a clean sound it, its muddy and awful, but distortion is not at all. I took it apart and checked for burnt connections or bad soldering and found nothing.  Blew everything out as well.  Warrantee ran out so i wanna figure this out.  New tubes.
