NO, THEY still make Parker MIDI guitars as a matter of fact (that was Parker's thing anyway - beyond the high tech stainless frets and carbon fiber)

when they have them they are $5K'ish


but MarioD is correct there are a LOT of MIDI guitar "solutions" out there

FTP,

Jam Origins MIDI Guitar 2 (it's only $100 and all you need is a GUITAR, even a nylon string ACOUSTIC since you take audio into PC and MG converts audio to MIDI in the PC - even has free demo but the DEMO is like 8 versions old so not a lot of bells and whistles and maybe not even best Audio TO MIDI tracking)

and a bunch of HW solutions as well.

I have FTP (set up for/on multiple guitars), the MG2 SW I mentioned above, a Roland Ready Strat and some other GK2/3 configured guitars, and a You Rock Guitar (that's a hoot)

============

However, I have to disagree with MarioD about string gauge on GK-2/3 type guitars.

The low E String, when tuned properly on a standard EADGBE tuned guitar, when in tune is set to 82.4 Hz and that is irrespective of string gauge.

(for ref: http://www.daddario.com/upload/tension_chart_13934.pdf )

That is, it does not matter if the string gauge used for that low E string is 38 gauge or 58 gauge - it will vibrate exactly 82.4 cycles per second when tuned properly. And the time for one complete string vibration (cycle) is ~12.136 milliseconds, again irrespective of gauge.

Good software, especially on a HEX PUP (e.g., GK-2/GK3 systems and even the FTP) can "cheat" a little since the string the signal is coming in on is already "a known." So the interpreting firmware/software MIGHT (could) be able to get away with only sampling the first half, or even the first quarter of a cycle (if the engineers really try hard) - and cut down by half or a little more the amount of time it needs to "decide" the MIDI note; thus improving tracking for low notes.

Of course the SW designers may want or need to "over sample" to be sure (e.g., read one full cycle or at least more than half) to be sure, thus trading "fast(er)" for (more) accuracy.
