Abstract: String fastener in the guitar body of an electric guitar, includes a bridge, carrying one saddle per string located at the upper side of the bridge, across which a string is arranged to run, one saddle per string fastened to the upper side, a downwards directed, pivoted lever arranged at each saddle, at which lever one string end is fastened, a tuning spring fastened with one of its ends to the lever and with its other end to the guitar body, which tuning spring strives to maintain a constant pulling force in a string, and which string fastener is provided with a vibrato arm, which when activated results in the bridge angling towards the guitar body, the vibrato arm being pivotally fastened to and running through the bridge. A fastening element maintains each lever in position, and a release device cooperates with the fastening element to release the levers.

Abstract: A device for string instruments comprising a fretboard with a plurality of frets, arranged at a distance from each other along the lengthwise direction of the fretboard and running transversely across the fretboard. Over the fretboard, at right angles to and above the frets, are lengthwise tensioned strings (8), intended to be set in oscillation for tone generation, where the lengths of the oscillating parts of the strings are variable for variation of pitch by pressing the strings against selectable frets. At least some of the frets include a straight fret segment (18) located beneath at least one of the strings, which fret segment is displaced lengthwise along the strings in relation to other segments of the fret in question.

Abstract: A string instrument with lengthwise tensioned strings above a fingerboard (18), where the strings are intended to be set in oscillation for tone generation and where the length of the strings' oscillating part is variable for the variation of the pitch by pressing the string against selectable positions on the fingerboard. The strings are running across a nut (16) arranged at the upper end of the fingerboard across the fingerboard. Such an instrument has a device with the nut including several nut parts (20, 22, 24 . . . ) that are arranged side-by-side across the width of the fingerboard and which are individually movable along the lengthwise direction of the fingerboard.
