The Hub

Our goal is to explore and teach acoustic principles that are directly relevant to instrument making. In 2026, we’ll be running four courses in different parts of the world, all focused on giving luthiers practical tools to better understand and control the acoustics of their instruments. We’re excited to introduce our very…

These maple purflings happen to be from Gurian Instruments, for what that’s worth. Also, if anyone has an idea of what this dot is and how it got there I’d love to he…
