Description

S.O.S. Sound Offset Spacer for Nylon String Classical guitars (Scale Length: 640-650mm)
S.O.S. improves the intonation at each fret
Easy installation to your guitar
Installs next to string nut
No permanent guitar modification
Designed and based on MTS theory
What is MTS theory?
MTS is an ultimate guitar tuning system based on the laws of physics. All fretted instruments have a fatal problem. That is, when player pressed the strings at the fret, the string tension is up and tone will be a little bit sharp, though the frets are set on the correct position. Inventor, Mr. Minehara researched and derived one formula to calculate the corrected (offset) value from string material, guitar scale and string height.
What is the material of S.O.S.?
Bakelite
Each fret pitch will be improved with S.O.S.?
S.O.S. improves the pitch from nut to 12th fret area. If you need to improve high fret area (over 12th fret), you need to adjust saddle.
Can I change the string gauge?
Yes, you can. Even if changing the gauge, but same string material, S.O.S. works well.
How is the effect, if open tuning or down tuning?
Usually, tension is getting lower, pitch gap is getting bigger. S.O.S. under down tuning will still improve the pitch better than normal condition.
Using a capo, do I need to re-tune?
After setting S.O.S, each pitch will be improved already. So basically, no need to re-tune after setting capo.
