Hey all I have a fender rumble 500 which is only a few years old and has never been pushed very hard. A few days ago during band practice it just suddenly had no power. We played about 20min it was working fine, took a 5min break (amp was never turned off) and suddenly nothing. Flipped it on and off, tried a new power cord, different outlet, even opened it up and tried a new fuse… still nothing! The strange thing is I’ll flip the power switch on and nothing happens, no light comes on, no sound, but a few seconds after I switch it off the light will quickly blink on and off once or twice - and sometimes a faint noise/sound from the amp for a split second. Anyone know if this might indicate what is wrong with it?? It would be a huge help to save some time trying to figure this thing out! Thanks in advance.
