Lately I’ve been trying different pickups in a jazzmaster parts guitar that I put together. I recently put in a set of Bacchus chrome covered humbuckers. The neck is a vintage PAF-ish 8k pickup and the bridge is a hot 15k Duncan JB type pickup (I guess you could say). The guitar and pickguard are routed for standard jazzmaster pickups, so to mount the humbuckers I just secured them under the jazzmaster pickup covers. Obviously, the pickup pole screws don’t line up with the holes in the pickup covers. It sounds cool to me as is, and I really can’t hear that the bridge pickup isn’t F-spaced; but I’m wondering how big of a deal it is that there’s a thin piece of plastic between the pickup pole screws and the strings. Is there a negative effect of that? Any thoughts?
