So I was playing around a little bit the other day and I noticed my amp was sounding... weird. And very quiet. I run a Boss eq pedal in my fx loop to boost the gain of the output stage and that's my only effect. Usually when you click the box on and off you notice a huge difference in sound but the other day it wasn't doing that, they sounded almost exactly the same. The volume was very low that day but I attributed it to my hearing loss lol. Anyway, I flipped her on Standby and biked uptown to buy smokes, I was gone maybe 5-6 minutes. I got home and noticed the power lamp on my amp was out. Fuse was blown so I replaced it and flipped her back on. Light goes on... then out again. Another fuse. What's going on? Are my power tubes shot or something worse? Help.
