Abstract
A tremolo bridge mechanism enables pitch adjustment of strings with both ends of the string rigidly attached to the stringed instrument. A pitch adjustment feature incorporates a deflection arm that is coupled with an actuating rod that pivots about a rotational axis as controlled by the tremolo lever. The pitch adjustment features can be configured to enable normal tremolo pitch adjustment or an opposite pitch change for a given motion of the tremolo lever. In a first embodiment, linkages between the actuating rod and deflection arm can be modified to provide variation in the pitch affect. In another embodiment, a spring array can be oriented in two different directions to provide variation in pitch effect for each individual string. In addition, a pitch adjustment feature may be removed, or a string can be routed around the deflection arm, to prevent pitch change with tremolo lever action.
