Set of 4 black reflector knobs; available new or aged. If you held the aged knob up to a light source, you would see first hand the level of detail we put into aging our parts. These knobs are slightly ambered to look like they have been in thousands of bars (cigarette smoke, anyone?) While the look is sublte, it really compliments the overall effect the aging has on the knob. Fits RS & CTS pots; 1/4"-inch shaft; fine spline.
