S.O.S. Sound Offset Spacer for Acoustic guitars. The Sound Offset Spacer is a simple but ingenious solution that improves the guitar's intonation at each fret based on MTS theory. MTS is a new method to offset the string pitch for fretted instruments. MTS derives the accurate offset value from instrument's string height, scale, and stress of each string.
Easy installation to your guitar.
Installs next to string nut.
No permanent guitar modification.
Designed and based on MTS theory(patent pending) to fit Electric and Acoustic guitars.
Includes 0.1mm spacers to set to correct height at nut.
