New PSG, photos

My new PSG was delivered at the MESA AZ show by Tom Baker of Sierra, who gave birth to it. Detailed photos are available to any who email me a request.
The instrument =:
29.730" scale on a 35.0" body, string ball to string terminator is 31.6".
14 strings tuned to C9, fret 4 is E9. Same gauges and tensions as an Eb9 on a 25" scale.
Keyless/gearless tuner is incorporated into the Changer. This eliminates the sharp bends in the string. The assembly is moved to the players left. This places all tuning functions at the players left hand = no picks. This also places the most string stretch motion behind the bar. The changer motion, and change rod density is moved away from the pickups.
The string terminator is placed at the players right. It is too simple for words, again, no sharp string bends. This has to be the quickest string change in the west/east/ or anywhere.
The bridge is changeable re material and geometry. This gives control over the tone/sustain via control of the acoustic impedance of the bridge. It can be changed without detuning.
Compression springs and E clips have been added to the changer rods to keep them in the bell crank slots when the strings are off. This also means that the adjustment rod(s) may be identified by feel, or by sight without pulling on them.
The neckplate is a drop in/on (into rails). The one shown is Etched Glass. The fiber optics and LEDs are not in yet. The neck is hollow to hold the circuitry for things to come. Neckplates can be interchanged for stretched tuning, quarter tone scales, and other reasons.
There is the option for two interchangeable pickups (bridge and neck). There is room for active electronics in the signal chain (high impedance input and line driver output).
Knurled knobs for the keyless tuner are on the way.
The plates around the pickup will be added once I get the neckplate length reduced a bit, ..I blew the calculation re length.
Fiber optic and LED fretboard markers are on the way, ..programable.
The hardware modules can be used on either players left, or players right. They can be used on S10's, D10's, S12's, D12's, 14's or ????
Sierra Session owners can add the tuner to the changer without removing it from the instrument, ..at least I did to prove the concept.
Tom Baker at Sierra did a great job on this one. Everything underneath had to be reversed and there was added travel because of the string length.
