i have a 1986 jb player jazz bass. it's getting old and it really needs new tuners. i'm gonna redo it and give it new life. i need new tuners and i thought about just doing it all. i'll get new pickups and a new bridge and maybe new wiring. we haven't opened it up so we don't know about wiring. i want to keep it cheap because i have three big time things i need to buy. i don't have a job so i need it to be cheap. any suggestions?
