Hi, I have a 1974 Fender Telecaster and a 1969 Fender telecaster. Both of them have microphonic pickups in both positions. I love their clean sounds, but cannot use them with even medium high overdrive at live volumes. First question: Should I avoid potting these because of resale value issues? (assuming the word about potting in wax actually works) Second question: Would it be better in terms of results, as well as resalve value, to replace the pickups and store the originals? Third question: Which pickup maker do you guys like for telecasters. Van Zandt, Lindy Fralin, or John Suhr pickups? Thank you very much!
