I assume that you are looking for the double humbucker types found in the 1000S and 1000A guitars? The ones with metal covers? if so, it would be a miracle to find one. The next best thing is to ask this guy to make you a clone. Only bad thing is he won't stamp the words "Travis Bean" on the metal covers:http://baileycustomguitar.com/
By any chance if you are looking for pickups to fit a TB500 model guitar, I actually have two originals that have never been used. Then I also have a pair of clones in white and a pair of clones in black.
Greg is a super nice guy. Not the fastest worker, but gets the job done and does it well. Good luck.
