Concentric Stacked Black Aluminum Knob

Fits pots that have a lower shaft diameter of 8mm and upper shaft diameter of 6mm. Secures with set screw. Lower knob is roughly 3/4"(19mm) wide .3/8"(9.5mm) tall, upper knob is 5/8"(15.9mm) wide, and 1/2"(12.8mm) tall.

Note; The upper shaft of the stacked pot used on all Aguilar and some Bartolini, and Nordstrand preamps will need to be shortened for the upper knob to fit in such a way to not leave too wide of a gap between the upper and lower knob. If you are ordering one of the above preamps from us, please send us an email prior to the order and we will be happy to modify the upper shaft of the stacked pot to fit these knobs free of charge before the order ships to you.
