Re: how come nobody makes 2-part strat style knobs so that
It could be done:
-Knurled/ridged top portion
-bottom portion would have an outer ridge like wheel-style controls.
Numbers for the top would not be needed. Desirable, but not essential.
However, it would have to be precision-made because the shaft for the wheel would have to be ridged and the wheel itself would have to lock on as it was mounted. Basically you could never change the pot without destroying the wheel.
