My friend has this really old Harmony Hollowbody bass. Does anyone know anything about these? Anyways, I'm going to fix it up and upgrade some things on it. The tuning pegs this thing has are insane. They are little guitar tuning pegs and they don't stay in tune at all. I want to drill bigger holes and install some vintage looking bass tuners. The nut needs replacing so I will probably put a bone one in. The electronics need fixing but I'll probably work with those when I get the thing. And last but not least, the bridge needs replacing. If anyone can give me information on basses like this or on how I should go about fixing it up, reply to this or email me at [email protected].
