I recently picked up a Pedulla Thunderbolt and have been attempting to do a light "restoration" on it (replacing all the stripped out screws, deoxiting the pots etc.) and next on the list is the neck finish. It seems to be some sort of oil finish, opposed to the poly on the body of the bass, and it has a few spots that look worn though to the bare wood. Does anyone know what type of oil finish the neck originally had/what I can use to touch up the finish? Also, I know the square truss rod nuts on these basses are prone to stripping if not handled carefully, mine looks a little rough but has no side to side play when coupled with the wrench and I would like to keep it that way; any advise on how to keep it from wearing down or what it takes to repair if it does start slipping? Thanks!
