nixyc posted a topic in Spider IV / Spider OnlineI have spider IV 75 amp. After being on for few seconds to couple of minutes, it makes a loud POP sound (from the speaker), then it no longer makes any sound. This can be repeated by turning the amp off and then on again. anyone know what's wrong with it? i'm guessing it's a hardware issue, i was wondering if anyone know which part is faulty. I do not live anywhere near a repair shop.
