Overladen tuning on modern guitars

In addition to working with old parlor guitars, there is one thing I do that should interest more. Overladen tuning on modern acoustic or electric guitars. The intonation means that the guitar is measured, the grip board is shortened about 1 mm at the upper saddle and a new toned upper saddle in bone is manufactured. On an acoustic guitar it can also mean that the stern trench is filled in and a new saddle trench is milled up in the right place. On acoustic a new toned stall leg is also mounted in legs. The stable leg usually tIpically need to be 3,5-4 mm thick to reach all intonation points. On an electric guitar, the stable is adjustable and needs no extra work.

After an oversaddle toning, the upper part of the grip board will fit much better. Two places to intonate provide the opportunity to get good intonation in two places on the grip board, my default is 3rd and 12th band, but you can choose other places if you want. The intonation distinguishes between different moods and string thicknesses as well as the string height at the 1st and 12th band and the neck relief. The height of the 1st band is made as low as possible and the relief is adjusted to about 0.10-01.5 mm in the middle of the board if there is a drawbar. The string height between bands and the underside of the string at the 12th band depends on the style of play, good if you know what string height you want or can measure it with blade dimensions on a guitar you enjoy!

Spun strings never get exactly the same intonation, although the difference for most is small on good strings. Unwound strings usually have the same intonation. On an electric guitar you can intonate the stable at the 12th band as usual and correct the difference in intonation for new strings. On an acoustic, the tone will be slightly worse with new strings, but always much better than with just the usual 12th band tone. I always double-check the intonation for spun strings when measuring because it happens that a spun string can be incorrectly made.

Perfect intonation is impossible to reach on a stringed instrument with fixed bands, but it is guaranteed to be much better with a proper oversaddle tone. I take SEK 2500 for such a job on an electric guitar, on an acoustic it can be up to a thousand lakh more expensive depending on whether the stool leg needs to be re-cut, not always necessary.

To make the intonation, two new sets of favorite strings are needed, some info about playing style and string height at the 12th band. You must be willing to convert the guitar from the original condition, which means that the fingerboard is cut about 1 mm at the top and the stable legs can be moved on an acoustic guitar. If it is an extra expensive vintage guitar, I can make a "shelf nut" so you do not have to cut the board, but it gets uglier and costs extra.

Some pictures of a new Gibson that really needed help with the intonation! The board was cut about 1,5 mm to reach the point of intonation that came closest to the 1st band (the unspun G string), the upper saddle was milled back to the intonation point of the other strings.

    • Three solutions. Either loose strap pieces or a curved strap á la True Temperament, or you convert to a regular bone oversaddle. The most stylish is a bone saddle.
