Yes, sad. In the 80s, the guitarist in my band also doubled on Stick. Met Emmett at the NAMM show when he was demoing his "Grid" MIDI system. I was VERY close to buying one, but at the time, I was getting heavy into synths and exploring fretless bass, so I felt I wouldn't have time to do it justice. Fast forward to 2 years ago, I started playing bass in a Peter Gabriel tribute band and have been considering a Stick again. Lots of looking at the website, figuring out what tuning might work for me, etc. They're hard to find and always seem to be around 2 grand. There was JUST an 8 string with MIDI on eBay for $2700 that was tempting me. A Stick triggering my synths could be awesome... But since I don't have that kind of money sitting around, I'll continue to fake it on 6 string bass.
Emmett will live on through all the musicians he influenced. RIP
