ABSTRACT:
A pitch changing device for a pedal steel guitar. The pitch changing device (10) includes at least one tension adjusting lever (24) pivotally mounted on the guitar body (14) for anchoring at least one guitar string (17) and selectively increasing or decreasing the tension on the string. At least one bracket assembly is provided including a first bracket (34) pivotally secured to the guitar body so as to selectively pivot at a first pivot point (40), and a second bracket (36) for engaging and pivoting the pitch adjustment lever (24), the second bracket (36) being pivotally secured to the first bracket (34) at a second pivot point (45) displaced from the first pivot point (40). A upper stop member (102) is provided for terminating the travel of the first bracket (34) at a point operatively associated with the normal pitch position of the pitch adjusting lever (24), and a lower stop member (42) is provided for terminating the travel of the second bracket (36) at a point operatively associated with the normal pitch position of the pitch adjustment lever (24). Further, actuator assemblies are provided for selectively pivoting the first and second brackets.
