Rickenbacker Vintage Style Control Knobs x 4. Not to be confused with cheap after-market push fit knobs, these are the genuine factory fitted item.

1/4 inch round shaft with grub screw fitting.

PLEASE NOTE THESE ARE THE AMERICAN MADE KNOBS AS USED BY RICKENBACKER FROM THE 1950s to 2023.

Later models use a smaller knob with a brass insert.
