im sorry that i jsut posted a thread on this yesterday but i cant fix my problem
my ad50 is making these really LOUD and high pitched squeaky noises when i change to some of the amp models or turn up the volume
idk waht it is and im pretty sure its not feedback because i put my guitar right infromnt of the speaker when it wasnt squeaking and that was feedback
also it makes that really loud annoying humming noise but i think thats just my really crappy cable
so if anyone knows what i could do to fix this or if my amp is just a defect please say so
