I have a 54 Reissue Telecaster Bass. I have the Seymour Dunkin Double pole pickup installed. As far as screwing the PU as deep as possible. Covering with gaffers tape etc, I am still getting a metallic clacking sound when I dig in deep with my playing. I want to route the pickup location approximately 1/8" down . This will give me additional clearance with the pickup and the strings. What is the easiest ,best way to do this on my own. Most of the people are understandably cautious about routing. Any solid suggestions would be greatly appreciated.
