Abstract: A tuner for stringed musical instruments which have a pickup for converting sound vibrations of the strings to electrical signals and a body being either hollow or solid with a front and back surface and a side surface extending between the front and back surface. The tuner has a tuner circuit attachable to an interior of the sound box with an input couplable to an output of the pickup and a digital display which displays a reference note closest to the note being played, a graphically intuitive indication of whether the note being played is above, equal to or below the reference note and a qualitative measure of the amount of deviation from the reference note. The tuner circuit automatically determines a closest note to the note being played and displays alphabetically the closest note.

Abstract: A tuner for stringed musical instruments which has a transducer pickup for converting sound vibrations of the strings to electrical signals and a body being either hollow or solid with a front and back surface and a edge surface extending between the front and back surface. The tuner has a tuner circuit attachable to an interior of the sound box with an input couplable to an output of the transducer and a digital display positionable on one of the edge or front surfaces of the body so that it faces a player when the instrument is in a playing position.
