ABSTRACT:
Apparatus for altering the output of an electronic string musical instrum responsive to bending of the string comprises a compressible electrically conductive member which has an electrical resistance which varies with the degree of compression applied and may be a conductive elastomer or a piezoresistive material. First and second holders are in contact with the conductive member and a current source is secured to the first holder and the string electrode secured to the second. Bending of the string causes the application of compression to the conductive member. The change in current flow is converted into an output which is a frequency variation which corresponds to the degree of bending of the string.
