I'm wondering if anybody could recommend a good online vendor to shop for some reasonably-priced aluminum knobs to swap in place of the stock BH volume & selector knobs (and obviously compatible / with the same internal width). My ideal find would be something semi-gloss black with graded 'notched'(?) sides and a decent position indicator that's about two-thirds or three-quarters of the total (base) diameter of the stock BH knobs - this last (size) factor being the most critical requirement.
Any suggestions would be much appreciated, thanks!
