I have a slight feedback issue with my Tokai Tele.
I had Dimarzio Twang King pickups fitted about 18 months ago, which improved the sound dramatically, but recently I noticed that the bridge pup tends to feedback at higher gain settings. It's an awful high-pitched squeal which I can stop by pushing down on the front of the bridge, so I tightened up the 4 screws in the rear of the plate and this helped a lot. However, using more gain and higher volumes makes it squeal again and I suspect that this is only a temporary fix.
I am wondering if I can either drill a couple of holes in the front of the plate to screw it down squarely and that may cure it? Would there be any other prep needed when I take the plate of to help fix the problem?
It's a Wilkinson vintage-style bridge, if that helps.
