I've got an Epiphone T-bird Pro IV which I haven't played for a few months. I had someone come round to look at it and it makes a buzzing/humming noise unless you have contact with the strings, or the bridge. I swapped cables etc and it wasn't plugged into any effects, so I'm not sure what's causing it. I replaced the 9v battery as recommended and it still hums!
Any ideas of what I can do to rectify this? Also, if in needs someone to look at it does anyone know anyone in Leeds?
Cheers guys!
