Congratuations, Hodge - I think you'll be pleased.
This is a wood we've used for years. As always there are lots of names. Royal Mexican Ebony is the new one; Katalox seems to be used most often. We used the older (Aztec) spelling: Katalo'ox, but in our neck of the woods where terminology was very general and often made knowing what you were talking about difficult, the most common name was "Cocobolo Negro".
The latin name is Swartzia cubensis, so it's not directly related to Cocobolo, not a true Dalbergia, and so not effected by the new blanket restrictions on rosewood from CITES. Be careful, however, if an instrument with this wood were to come into the U.S. from outside the country. Several areas where it grows have local restrictions meaning Lacey Act paperwork and permit documentation showing local restrictions were followed will come into play for entrance into (not exit from) the U.S.
While we used it on most of our instruments for a number of years, that use was typically on fretboards. Still we used it on bodies occasionally as well. Here's a photo of the back of an Alto Largo:
I still actually have this one, and as it's a primary instrument for string testing, it's gotten pretty gouged up below the bridge. Now that the testing has ramped way down, I'm going to try to make it a presentable instrument again and likely play it myself.
We built these in Central America and in those days used locally imported soundboard material. The most common was European Spruce - very popular with the local guitar builders, and we used it a lot as a result. It's the soundbard on the instrument in the photo. That pairing, as you might imagine, tends to be on the bright side, but there is a bit darker flavor these backs & sides give to the sound as well. So I'd say you have a nice combination and of course you can expect Jake will bring out the best in your selections.
