2pc. Large Black and Aluminum Retro-Style Knobs
These metal and plastic knobs fit 6mm pot shafts, and have a set screw for securing them in place on either knurled or flat shafts (note that on a knurled shaft you may need to file a small flat spot for better fit. We feel them to have a distinctive retro design, and have used them on a number of amplifiers with great success.
These nice large knobs are mostly plastic, with a metal insert where the pot. shaft goes and with brushed aluminum accents. Their "skirt" (the widest portion with the numbers) is 1 1/2" in width, and the knob is about .95" in height.
See the photo with the ruler to get an idea of size.
