It started the other day at my lesson, my bass would jump between distortion and normal tone, sometimes cutting out. I was using my teachers new beater amp, and figuered that was all. It was fine since then. Plugged it in again today, and from the get go there was a consistant clicking noise. It would cut in and out some more, and the distortion was very prominant this time, almost no clean tone. Eventually unplugged it for fear of something starting to smoke. Its active, Ibanez BTB 405QM. Any advice?
