I generally build things in sets of 4, as that is what fits on the bench, and one minimizes the amount of shuffling of jigs, fixtures, etc. when build a couple of the same size. (The last set of 4 had one of each size, soprano, concert, tenor, baritone, and there was much shuffling of things. They were all commissions. Here is the last set:)
The next set includes a much ‘wilder’ set of things. I’m getting around to building #100 (tenor), which will have some extensive inlay and has Florida rosewood back and sides, I have a commission (customer is not afraid!) for a concert out of box elder which has this bright red staining, and I got some really neat quarter-sawn crotch black walnut which should make some pretty spectacular instruments. One has single piece back and one has a bookmatched back. If you are looking for a ‘pair’ these tenors will be interesting siblings.
