ABSTRACT:
The invented guitarist's foot-rest comprises a tread-board, a pair of crossed legs to support said tread-board and a pair of parallel height regulating plates attached below said tread-board. Each of said height regulating plates is provided with recesses for receiving the rod connecting the upper ends of the free legs and recesses for receiving single or double wire staples attached adjacent to one or both ends of the connecting rod. A guitarist can adjust the height of the foot-rest merely by turning the connecting rod with one hand while sitting in a chair and holding. Further, it is preferable to provide a spring below the tread-board between the height regulating plates. One end of said spring is attached to one end of the tread-board while the other portion extending along said tread-board to prevent the disengagement of the connecting rod from the corresponding recess.
