An initial height of a first string of an instrument having a plurality of strings and a floating bridge is determined. The height of the plurality of strings is determined using a bridge sensor. The floating bridge is locked. A frequency of the first string is analyzed. In response to determining the frequency of the first string does not match a predetermined frequency, a tuning peg servo motor to adjust a tuning peg, thereby adjusting a string tension of the first string.
