We now offer an Internet access service to the I.T.S.™ software, from home!
The simple fact of changing the strings on a musical instrument drastically affects the intonation parameters, the replaced strings not being ideally identical, they have small defects requiring a verification of the intonation setting during this step .
This service allows you to preserve the precision of your musical instrument when changing strings, or in the hands of a technician, to obtain the best of your musical instrument.
We are the original company offering you the ability to maintain the intonation setting of your musical instrument, and this directly through Internet!
Made in France
Requirement:
After calculation with I.T.S.™, and if measured deviation was entered, Open string length become the length for calibration of the Open String Length, and against which the saddle will be placed.
NOTA:Typical core for electric guitar and bass guitar have hexagonal core made of tinned steel -> Choose 'Steel&Tinned' for electric guitar and bass strings core materials, then for wounds, materials used should be indicated on the strings package.
[Ls] is used to subtract invariable length of the Open string length for convenience, to use a shorter calliper.
Scale Length:mm
Fret No./Calliper:Fret. The nth fret counted from the nut, against which measurement will be taken with the calliper, from this fret side to the saddle side on the bridge along the string.
Fret width:mm
Calliper head width:mm. See calliper's head on the picture below.
Saddle length:mm. The length between the side of the saddle (in contact with the calliper), to the end of the open string (See below).
Calculated length Subtracted [Ls]:
(*) This calculator works either, if all entered in mm, or all entered in inches.Open String Length = Calliper measurement + Length subtracted [Ls].
Then,
Calliper measurement = Open String Length - [Ls].
Calliper measurement is the variable length, and Length subtracted are all fixed length along the Open String.
Here is an exemple of an invariable length subtracted measured on a bridge saddle, the calliper will be placed against the left side of the saddle here, for measurement and calibration:
Typical saddle [Ls] value for different kind of bridge:
As reference, this is some measured hexagonal core size for single wound string in different string diameter:
