Hi all I have a fender jazz type bass in need of a new bridge. Problem is that the stock bridge is recessed into the body and seems most the replacement bridges do not fit. Bridges that are made as fender jazz replacement bridges are too large to fit in the pocket recess. My options are to: 1) make a shim to go under the replacement bridge. My inclination is to go this route as it would be non destructive. 2) Route the body for the larger bridge. Concern is that the body has a gorgeous black lacquer finish. 3) Leave as is and continue to deal with walking bridge saddles. (not desirable). I haven't been playing it as much as it gets annoying due to the saddles moving. 4) Sell the bass. I keep thinking about that but just can't seem to do it because I really like the bass and it was my first bass. The bass is a Fender Aerodyne. Thoughts? I was thinking of using sheet delrin as a shim material.
