Sound Offset Spacer for acoustic guitars ( bronze string)

fitting scale : 643-650mm

S.O.S improves the intonation at each fret and easy installation to your instruments.

We only insert the S.O.S next to the nut between the fingerboard and the strings.

It is designed and based on MTS theory (Patent no. 4383272) and made in Japan.

What is MTS theory?

MTS is an ultimate guitar tuning system based on the laws of physics. All fretted instruments have 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. But S.O.S. doesn’t cover. You can consider to install custom MTS adjustment.

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 capo, do I need re-tuning?

After setting S.O.S, each pitch will be improved already. So basically, no need to re-tune after setting capo.

Any sound character changing with S.O.S installation?
Sound character depends on the materials which are constructed of the instruments. S.O.S material is bakelite not bone, so it effects to change the character a little bit.
