after hijacking somebody else's thread for information about black pickguards (thanks guys) I thought I might as well open my own thread about how to upgrade my new baby.
Side note: I'm new to this forum as I have been a proud Rickenbacker owner for ten hours now. A '98 jetglo 4003 found its way to my house:

And now I'm thinking about visual upgrades and playability. Already adjusted the pickups a little so it now actually has some output and the E string is as loud as the others. Also, I'll need a treble bezel thingie in order not to cut my right thumb.
Okay, lots of text. As to my question : Is there a source for black truss rod covers for a 4003 bass, or will I have to paint my white one? The problem is that I live in Germany ...
