Note: I perform many upgrades involving fitting control knobs to CTS and other American made control pots. There are many distributors online that seem to think a 6mm I.D. knob will fit onto a 1/4" diameter CTS solid shaft. This is incorrect. First, 1/4" equals 6.350mm and, second, in order to make a 6mm knob fit the CTS solid shaft it must be drilled out to .25"
