Perfect Fit for CTS Pots

These knobs fit my Gibson Les Paul upgrade perfectly. The bore size is accurate and the set screw holds tight without stripping.

Solid Build Quality

Heavy and durable. You can tell this is real aluminum and not plastic painted black. Worth the price.

Great Look but Tight

Looks amazing on my custom build. The fit was a bit tight on the shaft initially but settled in after a few uses.
