Here's my issue--I am installing a Gibson HB (490R) in the neck position of an Epiphone ET 290. The guitar has a bolt on neck with an exposed and frankly, cavity-filling tenon. In order to mount the Gibson correctly I would have to shear off the excess threaded screw parts from the bottom of the pickup. My question is this--can I cut them down without changing the tone or functionality of the pickup? If I can do this--why would they not simply use shorter screws for the poles? What advantage would the longer screws give? Thanks--and pics below (not mine but the same).
