[quote name='omikin' post='987417' date='Oct 13 2010, 08:02 PM']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![/quote]
I have the same bass and have exactly the same problem. I tried scraping the paint from the underside of the bridge where the earth cable contacts but it didn't change it much. I have an older Epi T-bird iv (not Pro) which I get no hum at all from even when using the same setup, cables, effects,etc. Any info would be most welcome. Ta!
Since originally posting this I noticed that inside the back cavity cover there were two wires ( a very fine red one from each pickup) had not been soldered onto the earth terminal of the lower left pot (as seen when looking from rear of bass). In fact both these wires had a rubber insulation sleeve over the ends of them. I removed this and soldered both onto the earth terminal of this pot and the hum has gone.[attachment=62749:100_3433.JPG]
