to each other, on a "fanned" fretboard, the frets are angled (spread like a fan) with only one center fret perpendicular to the neck's centerline. This gives the lower-pitched strings more length and the higher strings shorter length (comparable to a piano or a harp where heavier strings have different lengths).

. John Starrett revived the idea in the late seventies on his innovative instrument, the Starrboard. Rickenbacker employed a slanted fret, but it was not multi scale, or fanned. Novax Guitars among others offers such guitars today. The appearance of angled frets on these modern instruments belies the antiquity of this technique.
Scalloped fretboard:
Scalloping involves removing some of the wood between some or all of the fret. This is intended to allow a lighter touch for more precise fingering, while easing bends or vibratos (since there's no contact between the fingertips and the wooden surface of the fingerboard). It has some popularity with musicians playing

. Scalloped fretboards have not found widespread popularity because tonally accurate play requires a much lighter fretting hand than most guitarists can achieve, and often significantly heavier strings as well.
Fat frets: on older guitars (especially the

), frets were typically made out of thin wire, and some electric guitar players replaced that with thicker wire, for "fat frets" or "jumbo frets". Fat frets make bending easier, and they change the feel of the guitar. As well, large frets, offering more metal, remain playable much longer than thin frets. A side effect of a thicker fret is a less precise note, since the string is held over a wider surface, causing a slight inaccuracy of pitch, which increases in significance as frets wear.
Semi-fretted instruments
It is also possible to find semi-fretted instruments; examples include the
Malagasy ''kabosy'' and the
Afghan Rubab. Semi-fretted versions of guitars and other fretted string instruments, however, are usually one-off, custom adaptations made for players who want to combine elements of both types of sound. One arrangement is for the frets to extend only part of the way along the neck so that the higher notes can be played with the smooth expression possible with a fretless fingerboard. Another approach is the use of frets that extend only partway across the fretboard so that some courses of strings are fretted and others fretless, for example Ryszard Latecki'
Latar
Fret intonation
Instruments with straight frets like guitars require a special compensation on the saddle and nut. Every time a string is fretted it is also stretched, and as it stretches the string rises in
pitch, making all fretted tones sound sharp. When the saddle is positioned properly, however, the fretted tones all sound sharp to the same degree as long as the distances between the frets are correct. With the right nut compensation, the pitch of the unfretted string can be raised by the same amount. As a result, when the tension of the strings is lowered, the pitches of all notes, both fretted and unfretted, become correct.

s, frets are eventually bound to wear down as the strings cut grooves into them. When this happens, the instrument may need refretting (the frets are removed and replaced) or, in less severe cases, "fret dressing" (the frets are leveled, polished, and possibly recrowned).
