This morning i go to play the amp, and when i switched on the effects loop, i lost a ton of volume. I put brand new cables on everything in my loop just a few days ago. So, then i take a few different new patch cable out of the box and just connect the input to output, and i still get the same results. If i take the cable out of the loop and leave it open, I still get the volume loss. If i turn the loop off on the footswitch, I get all my volume back. 2nd problem: In the past 3 months the amp occasionally makes really weird noises. It only done it like 3 times in 3 months. Its like i will be playing, and all of a sudden their is a high pitched squeal in the background, and if you play guitar during these moments, it sounds almost like a bass. Even your high e string sounds like a bass being played.
