Chrome tuners you can get just about anywhere. I went with Hipshot Ultralight Clovers. Drop in replacement, vintage look, and less weight than traditional old school tuners. If you have an Epi Blackbird, you can either use an All Parts replacement bridge, or chrome Epi ones come up okn ebay fairly often. If it's a Gibson... it will be harder to find since Gibson doesnt like to sell bass parts ala carte. And for chrome pups, you can go with Mike Lulls or Thunderbuckers from Thunderbucker Ranch- both make '60s repros. And if it's a Gibson... then you can sell me your Blackbird pups! Look under the neck pup and see if it's marked "204" or "214"
