I know diddly squat about DB maintenance and have been given the chance to buy a nice looking blonde bass. However there are a few issues, a lot of rattle on F and F# on E string tried card under string at nut end still rattle, card under string at bridge rattle gone, removed card from nut rattle still gone. I was wondering how much (a ballpark figure) a luthier might charge to replace bridge, strings and carry out set up. I'm 74 years old not been playing DB very long, got my other DB just before first lockdown and play mostly Bluegrass and Country.
