I stood on my lead and ripped the input out of my Epi T bird. Had a fella look at it and he replaced the input socket on it. When I'm playing from time to time it cuts out. I had this problem before I had it fixed and put it down to the amp/lead I was using at the time. When it does cut out if I turn the volume on amp up I can still hear it faintly. What do you think the problem could be? It's doing my head in.
