Hey all! I have a charvel that Ive loaded Duncans in.. Ive always been pretty good with wiring and have changed way too many pickups. My only real downside with wiring is Im sure I use too much solder and am alil sloppy as far as looks go. Not nice clean little drops like a good tech, but never had any probs.. However. My Charvel has an issue. sometimes when I switch to the neck pup, it either isnt present or is faint. I switch again to mid or bridge and back to neck and boom.. Not a ton of play on the guitar, so doubt switch is shot. figuring a bad solder or something.. Any tips? Thanks
