Katalox is what you are thinking of- that was me who said it. It is very similar to ebony, and sonically I'm sure is pretty much the same.
I'm certainly not an unbiased source as I have five instruments made with it, but Joe was a big fan of the katalox top/guanacaste body combination, as I have with my five string. After he made mine, he subsequently made a few customs and specials with the same wood combination.
I gave Joe a really special piece of katalox to use for my bass, and it yielded four tops worth. I know he used another piece soon after, but he may or may not still have some- it was about three years ago. I know he's purchased other pieces and used for some of the other basses he made with it, so he probably has some on hand. I was considering ordering a 5/1 with the same wood combo, but I was "gently" told that it needed to wait until we moved to a permanent spot. I want another.
I have some sound clips of both of my weird Zons, as they both have a less common wood combo- walnut/ebony/bubinga and guanacaste/katalox, and they both sound pretty unreal. My walnut/bubinga bass is always my go-to instrument. Unfortunately, most of the clips I have are owned by other artists, so I can't post them. Hopefully in the next month or so I'll have time to make some clips and post them up.
