BRASS POT ADAPTER SLEEVE (SEE NOTE ABOVE ON MPK-24 KIT)
Do you want to put a 1/4" set-screw knob on your 1/4" knurled shaft potentiometer?  Do you need to eliminate the off-center problem when using a 1/4" set screw knob on a 6mm shaft pot?

Just slip one of our solid brass pot adapter sleeves onto any 1/4" knurled pot shaft or 6mm pot shaft to ensure a snug and secure fit for a 1/4" (6.35mm) smooth shaft knob. We have tested this adapter extensively, and it really does work great!

Note:  Will NOT work with 3/16" knurled shaft pots.  Those smaller knurled shafts are typically found in Crate and Peavey amps.  Not recommended for D-shaft type shafts.

Part #PAS-635

$0.95

(Need to order 5 of these for MPK-24 Kit if you have smooth shaft pots and set-screw knobs)
