OK knob, have to return because description was unclear on fit.
These do not fit 1/4'' shaft pots. I thought because it indicated they fit both solid and split shaft pots that would include 1/4'' solid -- but it doesn''t. These would be ok if you have 6mm shaft. Quality is decent, although the knurling is a bit finer than I would like.
