Honestly, most of the woods we use are domestic species, & many domestic species or supposedly "lesser" woods sound better than many coveted exotic species. Our mainstay species are ash, beech, sepele, walnut, ovangkol, & maple.
We have released a few one offs recently as we've been using up boards we've had in the shop for a long time, but that's not our normal course of crafting. That said, we may make a regular feature of some specialist feature snares, as this seems to be popular.
Specifically answering your question, we choose all wood species by trying them first. Our own wood species knowledge is very good (but always learning), but we sometimes base a decision to trial a wood species on advice from a specialist supplier we use. He travels the world acquiring some pretty impressive stuff, but always sustainably. We also regularly go & test boards at our supplier, & we get a pretty good idea of characteristics from that process too (we hang them up & hit them
Regarding this little snare, it's made of some zebrano left over from a kit build from some time ago. It's a wood we're likely to work with again in the near future, & one we're fairly familiar with.
