I've been playing a Fender Jazz Fretless, Ric 4001 and Spector Legend for the past decade but recently bought two Spectors, another Legend and a Euro, with a PJ pickup configuration. I never realized how dependent I've become on anchoring my thumb on the pickup. The p pickup is a real challenge due to the bump, for lack of a better word, for the screw at the top. I rarely look at the bass when I'm playing and now I'm finding that when I move my right hand around it ends up on one side or the other of this bump. This has become a real nuance. I'm thinking about making a small "adapter" to make the top flat. Anyone else have a problem like this with a workable solution?
