Stringtheory is a fretted instrument (guitar, bass guitar, ukelele, banjo) performance and accessory company. Our mission is to revolutionize the sound and functionality of stringed instruments through patented innovations, cutting-edge design, and advanced materials and technology.

We focus on resonance, tuning and tuning stability, the fundamental aspects of any instrument. Our patented solutions address a critical design flaw in guitars and bass guitars that causes them to play out of tune. By enabling individual adjustments at both the bridge and the nut, our products ensure perfect intonation across all strings and positions.

Our practical, easy-to-install designs replace existing nuts without modifying the instrument. This precision-engineered approach brings the accuracy of watchmaking to the world of guitars, allowing players to make precise intonation adjustments at the nut, resulting in consistently accurate tuning regardless of string choice or pitch.

Stringtheory's groundbreaking technology is set to become a universal standard, transforming the playing experience for musicians worldwide. With hundreds of millions of existing guitars and millions more produced annually, our goal is to equip and transform them all, bringing perfect intonation within reach for every player.
