I need help with my marshall avt 100, When i use OD1 and OD2 (Overdrive 1 & 2) i get a loud buzzing sound (used other speakers and still get the buzzing sound) that increases as i increase the gain or volume. Also the fan in the back of the amp is louder than i think it should be when the amp is switched on,
any constructive help will be welcome
