We have been waiting on these for a *long* time and they have arrived! These are the custom dual concentric pots (two knobs on one shaft) we use on Portal Drum and future modules to increase panel density without reduction of ergonomics. For those that tried these at Superbooth, we'd also taken your feedback and changed them to a larger body size which means the shafts are much more stable and not so easy to turn (the previous ones were pretty loose and easy to bump - not something you want on a dual concentric).
The knobs that fit these are being made and full production will begin shortly! Most of my work will begin soldering about 10,000 wires to these things so I'll be busy busy :o
