Multiscale Guitars & Scale Length

How tuning, string feel and fret layout come together in an OD guitar.

What is a multiscale guitar?

A multiscale guitar uses different scale lengths across its strings, creating the angled layout often called fanned frets. Scale length is the vibrating length of the open string, measured from the nut to the bridge saddle. The bass strings usually have a longer scale than the treble strings.

A standard-scale guitar uses the same nominal scale length across the strings. The choice between the two depends on your tuning, string gauges and playing preferences.

Why consider multiscale for lower tunings?

Low tuning can leave a string feeling loose. For the same string and tuning, a longer scale increases tension. It offers another way to shape the feel of the lower strings, alongside choosing the string gauge.

There is no single scale length that suits every player. Consider your preferred tuning, picking attack and how much resistance you like under your fingers. The six- and seven-string tuning guide provides starting points.

What makes the fret layout comfortable?

The difference between the longest and shortest scales affects the fret angles. So does the position of the perpendicular fret, where the fret sits straight across the neck.

Omer’s existing multiscale recommendations use the ninth fret as the perpendicular fret. Its position matters when considering how the first and highest frets feel to reach. Comfort is personal, so the layout should be considered alongside the neck and your playing style.

OD multiscale starting points

These combinations are taken from OD’s existing specifications. They are options for discussion, rather than requirements for a particular tuning. Measurements below run from the shorter treble scale to the longer bass scale.

Strings	Scale combinations
6 strings	25.5 to 26.5 inches, or 25.5 to 27 inches
7 strings	25.5 to 27 inches, or 25.5 to 27.5 inches
8 strings	26 to 28 inches

Other scale combinations can be discussed for an individual build.

Does multiscale replace intonation adjustment?

No. Every guitar needs correct intonation adjustment, whether it has straight or fanned frets. Multiscale describes the scale layout, while saddle adjustment is part of setting up the instrument.

Omer designed the OD mono-rail bridges so each string has its own bridge position, with adjustment travel for intonation.

Changing tuning or strings

A change in tuning or string gauge can mean the setup needs attention. Neck relief, string action, nut slots and intonation work together. Read Is it setup time? for relief and action checks, and Things you should know for the role of the nut, neck and bridge.

Luthier Omer Deutsch considers scale length as part of the complete instrument, alongside tuning, string count, neck feel and the player’s musical needs.
