I just scored one last weekend. I'll put up an NGD thread when I get some good pics. A black Reflex HH hardtail with piezo and Game Changer circuit.
Besides pics, I want to do a shootout with the Reflex and my Axis SS guitars.
From reading about it and plugging it in a little bit, I'd say if I were a touring pro with a rig that is controlled by a MIDI foot controller or even better, a computer, and playing into an AxeFX rather than an amp, the Reflex with the Game Changer circuit would be a great choice. You could play your entire gig without having to take your hands away from the strings to flip the pickup selector switch, or even to flip from electric to acoustic tones. If your rig has acoustic guitar presets, which I think modeling units like the Axe FX do, a MIDI message from your MIDI controller or a computer could switch off the magnetic pickups and switch on the piezo when you need to play an acoustic part, and switch to the acoustic guitar preset on your modeling rig at the same instant.
And MIDI messages from a computer or MIDI controller could make all your pickup selector changes for your electric guitar parts.
You'd be able to just play your parts, and a computer or a tech offstage could handle preset changes to your effects, amp and the guitar.
Aside from the Game Changer circuit, a chambered body with mahogany tone block and those amazing sounding Axis pickups... I'm excited to hear it up next to my solid and hollow body Axis SSs.
