Hi everyone, first post here. I recently purchased a very nice 90's Epiphone DOT, with Seymour Duncans, Grover tuners, and new bridge (installed by prior owner). Only thing I believe to need done is to replace the p'up selector switch.

How hard is this to do DIY? It appears to be close to the F hole, but I don't want to make any rookie mistakes and scratch it. Also, any suggestions for the switch's manufacturer / seller? Thanks.
