I've got a 68 and 69 tele that I love the sound but the band I play in plays a lot of rock and such. If I run my dyna comp even at very low comp levels with overdrive it squeals like a gut shot pig. Here's what I've done: Replaced the springs for surgical tubing, and on the bridge put a small amount of wax under the back plate of the bridge. Any advice on how to tame the squeal just a bit? I don't want to totally wax pot them because I don't want to change the tone and kill the value. I've heard of potting them with lacquer or something like that but not sure. Any advice?
