i have come into posession of a 72 Rick' 4001 with what appears to be fender humbuckers and some really messy electronics (being gutted and replaced as i type), and am considering replacing the pickups. I play the majority of the time with a pick, and want to be able to get a nice bright "grinding" sorta edgy sound out of this old workhorse, but also be able to get a nice smooth tone out of it for our quieter songs. Any suggestions? Will changing the pickups be worth the money, or should i put it towards a new stingray ? Also does anyone have an opinion on whether fitting a piezo kit to this bass would be a bright idea? thanks.
