Abstract
An apparatus which clampingly engages the neck and the strings and fingerboard of a stringed instrument for selectively adjusting the pitch of the strings. The apparatus includes positioning guides for aligning the apparatus with respect to the frets which are disposed along the fingerboard and a pair of relatively thin, resilient string-engaging members which reduce undesirable string vibration and maintain proper string contact with the frets.
