I got this set from Juan Alderete of The Mars Volta in a trade deal for a '62 Fender PU. He had them in a '62 P-Bass, but I haven't installed them yet. If anyone has information on these, I'd really like to learn more about them. They were made by Red Rhodes. This is the only Velvet Hammer P-bass set I've seen. I've found only limited info online on the six-string guitar pickups, which appear to be highly coveted, and considerably more common than the P-Bass set. I just listed this set in the Classifieds, by the way.
