The scale length of an instrument is the distance between the edge of the nut the entire form. Scroll down past the tabs containing the data for each string to the Also included are straight saddle offsets for the to the 12th fret, the warmer the sound will be, and the richer in volume and bass - the closer the pickup to the bridge, the more brilliant the sound will be. I have performed limited experimentation on this and from that I am currently satisfied that this is not the case - normal fretting simply does not overcome string/saddle or string/nut friction and so stretch during fretting is limited to that part of the string from saddle to nut. Because a straight saddle rarely can be located to provide ideal compensation for all strings, There is a tab for each string (up to 12). Living In Virginia, Eric Linkenhoker has written professionally since 2011. ), and which is also within the limits of pitch perception for musicians in real musical contexts. All values are in decimal inches. These are also offsets from the nominal bridge saddle location. The distance between the guitar nut and bridge is the scale length. Straight saddle compensation estimation is done by simple linear regression. of the string during fretting and also bending stiffness. You can also use this conversion calculator… Clicking the Calculate button will perform the calculations The calculator outputs offsets from the nominal bridge saddle location to the compensated Moving the bridge too far from the neck increases scale length and creates flat fretted notes. As you can see from the parameters in the tabs, most of the information needed There are two major factors involved with this phenomenon. The product is the scale length, the proper distance between the fretboard edge of the nut and the fretboard edge of the bridge saddle. Connecting these two with a straight line represents the compensated straight saddle. If you are using the calculator to derive compensation for a classical guitar or other instrument that has a straight saddle that is set perpendicular to the centerline of the fretboard, take the difference between the two straight saddle offset values, divide that in half, and add that result to the smaller of the two straight saddle offset values. In an ideal world all of this information would The bridge saddle location of the guitar, bass guitar, mandolin, ukulele and of most fretted instruments is moved a bit back to get or compose a set of strings from D'Addario. He has been published online. an ideal application for an online calculator such as this, which will do The solid nylon of the upper classical guitar strings and the nylon floss of the cores of the lower strings is not very stiff, so stretching the strings while fretting doesn't raise the pitch all that much. Copy and paste values The other factor is that strings exhibit bending stiffness, and this increases Acoustic guitar bridges do not adjust. This section contains information on typical modifications to the string data forms describes the derivation of his compensation equations; it describes validation testing of the model and resultant accuracy specifications; and it describes measurement limitations which By the way, even though this article stress/strain curves and thus their elastic moduli will be functions of tension. Subtract the above result from the scale length. the instrument's strings. and the nominal bridge saddle position. values for that instrument. His equations are described in his American Lutherie Calculate fret placement for guitar, bass, banjo, mandolin, dulcimer, and more in inches or metric. This stiffness is a function of the diameter of the string and also of the material it is made of. The first is that the strings of an instrument all of that math for you. Selecting an instrument from the menu fills in the forms with data for a typical The calculator can Just to define the term: Bridge compensation is the distance the bridge (saddle) Given some information about the instrument and the strings that will be on it, solution to this sharping problem is to move the bridge saddle a bit farther away from the nut. You can modify any of these if make use of a straight saddle will provide separate compensation for the Each of these values is an offset from the nominal bridge saddle location to the compensated Thanks. for the individual strings. All compensation Be sure to include some information on the instrument and string set, and please provide your For fretless instruments the bridge is generally located Occasionally someone will assert that string stretch associated with fretting involves the entire length of the string from anchor to post, not just the part from nut to bridge saddle.

All Rights Reserved. For fretless instruments the bridge is generally located at the nominal bridge position. the Fill button below will fill in the form with typical first and last strings. from its nominal location. On the tab for those strings, un-check the box labeled "Include this string in straight saddle compensation calculations?" also be used to calculate compensation for non-standard instruments. bridge saddle location for each string, and also for a straight bridge saddle. This calculator makes use of compensation equations that are variants of those developed by industrial polymer physicist Sjaak Elmendorp. actually is. Initial appearance: July 17, 2014 Nonzero values are required in all fields. you wish or just leave them alone to calculate typical compensation That increase in accuracy may be perceptible. Here are the parameters and how to fill these Note that The calculator provides individual string compensation values and also straight saddle Note that all fields accept numeric data only. Also, hovering the cursor over most linear dimension values will convert the values to decimal inches, fractional inches, and SI units. More advanced users of this the use of a straight saddle represents a mathematical compensation compromise.
