I have - now - finally tried it out, thoroughly, and it's neither better nor worse than anything already out there. Latency, mis-triggering, and a couple of other idiosyncrasies irks me the wrong way still. MIDI wasn't made for guitar, neither MPE or MIDI 2.0.
First, if they should go headless, they should change the entire bridge assembly out. Since it seems important that it stays and is in tune, the small crank key (remember when you had to start automobile engines with a crank at the front?

) is nothing but a major gaffe.
Use regular headless bridges, they're around, and no one has to have a license since the patent has ran out since long time ago. It's easier to have the Steinberger type where you can tune with fingers only, and even use double balle end strings to your liking or not. If one should have it, I would love a tone control on there too, for regular guitar sounds. Rather wished a tone control, than a tap switch for single coil tones. Although the actual guitar felt just ok to play with regularly, it's nothing new under the sun.

1. I definitely want MIDI out directly from the guitar, and no adaptors, or KLUDGES made for it to work.
2. If they bothered to make a special proprietary guitar to go with the Hex MIDI pickup they should walk that extra mile with making it in composite material, especially neck AND body to buck and isolate all resonances, in order for the strings not to resonate or cause mis-triggering by dead spots, or wolf notes along the neck.
3. And this one beats me. Seriously. Today, most people, or more and more, resorts to plugin synths of their PC's and Macs, and in there, there's always an inherent latency too no matter how little. And whatever this is, it's added on top of a) this guitar pickups latencies/conversion b) IRL real time latency from speakers to your ear (3-5 ms in normal cases). So all this adds up to the c) "onbard" latency of 7-15 ms it takes. I felt that the response of lower strings was more latency that higher notes. It lagged big time when I tried it.
And today when we are seeing such things like
JamOrigin MIDI Guitar 2 with about the same latency and the same tracking idiosyncrasises like hardware hex pickup equipped guitars, polyphonic, but that you can use ANY guitar with ANY cable or ANY pickup, I wonder where the ***** the demographic for things like these exists? Where's the customer base? And considering price of MG2 compared to this hex equipped guitar.
The JamStick has absolutely no better tracking/latency than MG2 (JamOrigin Midi Guitar 2), and works the same. Some glitches here and there as always, in note conversion. If there was something "killer application" or killer design in hardware on alternative detection of pitch that made this one superior to all others already out there, then it would - maybe - have some viable merit.
Still the tuning mechanism is way out of anything ergonomic and workable. If you lose that small tiny crank key, as people do with picks and allen wrenches to FR systems, you're toast basically. This one rubbed me the wrong way, the most of it all. Wonder what they'd been smoking at the design table...don't wan't any of it. They should use Occams Razor in that case, when designing.
Verdict: meh-diocre.
