This shaft Adapter are made by Don-Audio specially for instrument knobs which must be controlled by a switch or potentiometer that has a thinner shaft than the knob. The Shaft Adapter is made of brass and fits to 6 or 1/4 inch Knobs. You can choose between 1/8 shafts or 3mm shafts to adapt to the 6mm or 1/4 inch shafts of the knobs.
All reviews:
Excellent tolerance When I could only have a 4mm spindle manufactured, these fit perfectly and allowed the larger size to be used.
