A friend of mine has me as the go-to for his bass work. His request this time: "Make the pole pieces level on my Musicman pickup" He plays on top of the pickup and digs in, as well as prefers low action. I know, the pickup is built to compensate for the radius of the fingerboard. But my buddy hates the feel of the pole pieces on the A and D strings when he plays. The cover comes off and I can put a shim between it and the coils, but there's no perfect medium. Either the A and D poles protrude or the E and G have craters and the edge catches his finger. Is there any way for me to push the 2 polepieces down to make them level? Or a new cover? And no, electrical tape is not acceptable for him. I know it works, but he's vain.
