1995 Hamer Cruise Jazz Bass with Gotoh bridge. 'Weak e string' as explained by the seller is soon diagnosed as fully decomposed pickup foam under stock Duncan pups. Lots of corrosion, spent tuning machines, crusty pots--apparently perspired on heavily for 23 years. Fair price though.
Easy 'nuff':
--Strip (no need to remove neck; action already good, now better with slight truss rod tightening)
--Vacuum old pickup foam dust out
--Install full set of replacement stainless bolts onto Gotoh bridge
--New ultralight Schaller machines (m4 180) to replace stock from same brand (stock 7/16" peg hole needed widening to 9/16")
--New Duncan Apollo jazz pups.
--New passive harness (Vol, Blend, Tone--nice with noiseless pups)
--New output barrel jack
--New nobs
--6 nights of vigorous hand cleaning
--Fretboard feed and wax
Labor free and 100% amateur. Plenty output now on all strings and neck is playing great with medium-low action!
