Abstract
The invention as described herein consists of a pitch-changing arrangement as may be used in a pedal steel guitar to improve the quality of the sounds emanating therefrom. The invention incorporates a tone ring for transferring the string energy from the neutral position raising lever directly into the guitar cabinet. The invention also allows for the pitch-changing device to be stopped in the raised position by the guitar cabinet slot thus imparting the string energy directly into the guitar cabinet.
