I sold my CE-5 a while ago and the only thing I really miss about it is its cool double "filter" pot. You can kind of see it on the far right in this pic:
The inner part of the knob turns independently of the outer collar, and they control an HPF and LPF. So it's kind of like a dual pot only you can control the two parts separately.
This seems to me to be a nice way to do something like a coarse/fine split for a modulation control. But I have no idea whether pots like this are available, or indeed what term to search for.
Anybody seen 'em for sale?
