Everything the guitar taught one builder, in one place.
Jason Colapietro, founder of Suede AI, is a self-taught guitarist who wrote the books, built the references, and shipped the tools. Two published guitar volumes, an engineering-grade signal chain reference, chord libraries, an AI practice coach, and a network for musicians. All of it live, all of it by one person.
