Torsion oscillated spring corded contrabass guitar

摘要

The present invention is directed to a contrabass guitar which oscillates the pitch of the guitar by the use of torsion. The strings of the guitar are adjusted by use of a torsion control means connected to a foot pedal to allow a player to easily adjust the pitch of the guitar while playing. The contrabass guitar includes a floating bridge and a stationary torsion block with a plurality of helically twisted tuning control rods attached. The floating bridge contains a plurality of pitch tuning cylinders connected on one end to respective strings and on the other to the tuning rods. The floating bridge moves along the body of the guitar in response to the torsion control means causing the tuning cylinders to slide over the tuning control rods and to rotate according to the twists of the rods creating greater or lesser torsion uniformly in the strings. Depressing and releasing the foot pedal allows a player to adjust the string torsion force by using only the foot pedal without having to manually adjust string tension interrupting the playing of the guitar.
