Abstract
A pedal steel guitar comprises an improved pitch changer mechanism for effecting string pitch changes. The mechanism comprises a plurality of pitch-changing fingers, each mounted for pivotal movement with respect to a selected axis and adapted to be connected to a guitar string end, so that tension on the string end will urge the finger in a selected direction, a stop for limiting movement of the fingers, a number of pitch bars each adapted to move relative to said axis and thereby mechanically force at least one of said fingers to move so as to change the pitch of the string attached thereto, and pull means for selectively moving the pitch bars so as to selectively change the pitch of the strings attached to said fingers. The changer mechanism may be adapted to raise or lower the pitch of each string.
