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.
