hi guys, as i was playing my guitar just now, my amplifier suddenly give out a very large sound follow by a very loud siren sound from the amp,that was aso a smelly coming out of the amp. Has anyone encounter a similar problem? my amp is a solidstate amp, has my amp spoilt? i look at the back of the amp but cant seem to find anything burnt or something, but there was a smell n my amp would give out a loud noise when i turn it on. any advice? is it time to get a new amp?
