So I don't know what happened to my amp but i was about to plug in my guitar and tune it up then it happened the tuner worked like i was able to tune up my guitar with the built in tuner but when i turned it off to play i wasnt getting any sound so i went through basic trouble shooting i checked my knobs and my cable i plugged my guitar into a different amp it worked just fine so then i wondered what the issue was so i plugged in my aux cord to see if if that works which it did i factory reset all the lights work i have no idea whats wrong with it can someone help please
