The Mission

Pocket Luthier exists for the player, not the tech. A roadie doesn't lecture you — they hand you a tuned guitar before you walk on stage. That's the standard we hold ourselves to: practical, clear, and always in your corner.

Who It's For

Whether you've been playing for six months or sixteen years, guitar maintenance shouldn't require a luthier's diploma. Our tools speak plain English, explain the "why" behind every step, and catch the details your ear can't — like a 1.5 Hz intonation drift that makes chords feel slightly wrong without you knowing why.

What's Coming

The Intonation Assistant is just the first tool in the kit. Action height, nut slot depth, truss rod guidance — every adjustment a guitar needs, broken down into steps any player can follow. More tools are in the works.
