I'm Russ Maschmeyer, originally a software designer and now a passionate luthier too. I wanted a modern design tool that could help me instantly understand the tonal impacts of each decision, building upon the research of Gore & Gilet, Christensen & Vistisen, and Bernard Richardson. I thought other luthiers might want something like that too.
