Ervin Somogyi is often referred to as the luthier's luthier: His guitars are among the most well-known and sought after custom instruments being made today. Ervin has influenced the custom guitar world, not with his own guitars, but also by training some of today's top builders and by authoring his two-book series the Responsive Guitar. For our debut episode of Luthier on Luthier, Ervin and I cover a lot of topics including what he enjoys most about guitar building, his approach to understanding how guitars work and his thoughts on design.
