Hi All: I recently picked up a Reverend Rumblefish. The bass has suffered some mods. I'm currently preparing to do something with this bass ( either restore it or mod the hell out of it ) so I'm doing inventory of original vs changed parts. I pulled the pups and believe that they're not original. I can't find any markings on them at all. They are single coil from what I can tell with black shiny electrical tape wrapped around the coil. They are neck and bridge length with black / white wires on the neck pup and black / red wires on the bridge pup. The wires pass through small eyelets. The bobbin flanges are plastic. The dominant feature for me is the large rectangular ceramic (?) magnet across the bottom of the pole pieces. Does anybody have any idea who made these pups? Any help is appreciated.
