Hey, my little orange Ad-5 suddenly started sounding really muddy at my last practice. Ive had a repair guy look at it and he's checked the valves and electrics and he says all is fine? I checked the speaker cone and that hasnt ruptured. What the hell could it be! Speaker coil? Any help or advice would be great! By the way, I always play it cranked if thats of any relevance!
