Has anybody ever figured out how many ways there are to play a C Major Chord on a U-12? Not including extra pulls and using your teeth?

Infinite - you wouldn't be able to hear most of them beyond the 24th fret though, especially those between the pickup and the bridge.
This fact begs a little definition.
If you mean a triad, 1 3 5, ie c f g, and limit it to 24 frets, then, without being at my guitar, I would estimate it as follows:
Let's see there are at least eight variations using pedals or not.
1. no pedals with adjacent strings.
2. no pedals combining top chromatic strings
3. no pedals using middle f# and two others
4. a+b pedal
5. f lever + a pedal
6. Boowah pedal
7. eb lever
8. Eb lever and pedal six in my case (returns the flatted e string)
Now let's multiply this by four octaves over twenty four frets and three string grips per position for a twelve string guitar = 4 x 3 x 8 = 96 at a minimum.
To be realistic I would multiply this by 20% for something I've forgot.
That's alot of Cs! |

Ooops. there are only 3 octaves per 24 frets... and the Boowah does not repeat for different string grips as well as some non pedaled positions.
I guess I gotta be at my guitar.
Fun exercise though. |

Jim, you forgot P5.
D'ohh. That's an analog of AF
And don't forget P7, with its F# at open.
Rather than look at how many places you can play a C chord, my brain prefers the inverse: how many chords can I hit open?
Although I prefer the other Unified (I prefer that term over universal: E9 or C6 may both find uses in all genres, making them universal as well), I'll discuss E9/B6.
B: duhh. drop the Es, it's in the name of the tuning
C: OK, this is a reach and a pain. Either split A/X or half pedal A, and drop the G# (either half step or split with B) and E strings.
C#: P5 or A/F
D: drop 2, hit B and you HAVE a couple F#s
D#: drop Es, Bs and G#s, but WHY?
E: yup
F: raise Es, G#s and half pedal A
F#: X and drop 2 whole 3t
G: drop G#, drop 2
G# P8
A: AB pedals
A#: X, drop 2 half step, raise E.

Since he didn't ask for multipliers like how many 3-note grips, I'd say 27 on a 26-fret neck.
Every chord is available at every fret .

With multiplier of 6 grips, but then there is? It gives me a headache.  and what about implied chords or suggested chords.

| Lane, I like your attitude. Who needs a stinking bar? Perhaps just a PSG capo. |

| Seriously, when I want to freak out the inquisitive guitar players I pick a round of 4s ragtime tune and don't even set the bar down ! |

On a U-12 or even a full-featured E9th, you can play every note at every fret. I'd make an educated guess that there are at least 12 positions for each major chord. A few of them might sound a bit funky because of tempering, though.
Here are the most common positions for the C E G triad on E9th. The positions at frets 2, 7, 9 and 12 are omitted because they would probably sound out of tune (in my opinion).
- fret 1, strings 10, 8E, 7 (low octave)
- fret 1, strings 5, 4E, 1
- fret 1, strings 5, 2, 4C
- fret 3, strings 6B, 5A, 4
- fret 4, strings 6, 5AX, 2
- fret 5, strings 7G, 5, 2D
- fret 6, strings 7, 5X, 2DD
- fret 8, strings 8, 6, 5
- fret 10, strings 9, 7, 6B
- fret 10, strings 2D, 4C, 3B (high octave)
- fret 11, strings 10A, 8F, 6
- fret 11, strings 5A, 4F, 3 (high octave)
Then it starts repeating at the 13th fret.
