Ervin Somogyi’s is a landmark two-volume treatise that shifts the focus of lutherie from "how to build a guitar" to "why a guitar works." Often referred to as the "bible for guitar makers," it represents over 40 years of Somogyi's research into acoustics, physics, and the mechanics of tone.

What began in 2001 as a straightforward "how-to-build-a-guitar" project evolved over eight years into a monumental two-volume dissertation on the guitar, grounded in Somogyi's four decades of hands-on experience and thought.
