I got this one in Flagstaff, AZ. Not sure where else has them. Had to drive up 2+ hours from Phoenix to even try one out. You probably could find a store or two in Los Angeles that carries them. Best bet is to go to their website and submit a contact foem. That's how I found this one. None other than Aspen Pittman's daughter, Autumn, herself answered it.
Thank you for your kind answer, however, I mean the gold colored box with five knobs and round rotary sitting on floor above expedals in your post picture.... Maybe it is connected to control port of FC6's.
