Re: Help ID'ing a bass
I meant the outer casings of the pickups themselves, not the metal RF screening covers.
Some of the old MIJ "lawsuit" era basses came with small, metal covered Maxon pickups, roughly the size of a Gibson LP Deluxe mini-humbucker. The same pickup appeared on both P and J "inspired" instruments.
In your headstock photograph, below the A and D machineheads, there appears to be a less discoloured area of the finish, roughly wear a manufacturer's logo might originally have been attached. (i.e. A solid, plastic or metal name badge as distinct from a decal.)
