For the guitar players and builders...

What's your opinion on THIS?
 
Other than making your guitar neck look drunk that is!

 
Wha'd they do to the frets?

I like the comment "it never goes out of tune".
 
CH's very own pro-luthier (Spacey) should comment on this. :)   

That's if you include the Evertune system.  In fact, it was watching the demo videos for that that I came across the True Temperment stuff.
 
HERE'S/ that website.  Also interesting, but no trem version until 2015 (it's best use IMO).

Yeah, but, your guitars look waaaaaayy better than that thing does!!!!!

I'm a firm believer that if you want an instrument to always be absolutely perfectly in tune in all ways at all times WTF are you doing with a guitar? 

I like the idea that you might be able to buy a neck and bolt it on any old plank of wood.
 
I wonder if they do compensated nuts?
 
Do you get a special set up for YOUR favorite set of strings?
 
I've always wanted to hear one of these "solutions".

What happens when you play music with another guitarist? Does he have to have one too? lol.

No. He can get one of these instead:

It's not our fault if the drummer's always ahead of the beat. 

Because the tone of the string is determined by the thickness and tension, and because the tension applied by bending the string to the fret varies from string to string, a simple division of the fret distances so that each string is fretted at the same length should produce some minor variation of the pitch achieved on heavier vs lighter strings. Some guitars take that into account by angling the bridge relative to the nut, but if the frets are all parallel to one another and not angled as well, there is still some error.
 
The degree of fret variation in the picture looks too extreme to accomplish "perfection" which in any case would still be defeated if different gauge or composition strings were used. And of course unless the frets were constantly moving around as the strings stretch decreasing the unfretted tension, there is no way the guitar is never going out of tune. Loss of tune has nothing to do with fret location. Ever hear of a piano tuner?
 

Might be cool for an acoustic, classical or hyper strict no bending jazz but it looks like it would be a bunghole to try and play blues or anything that has even a hint of string bending. Also after years of keeping fret fingering as tight against the fret as possible it would be an adjustment and probably lead to bad habits when you wanted to switch back to a a standard fretboard.
 
And yeah... string gauge and other factors would likely seriously screw with it. I'll pass.

That's what I was thinking. In the second video, the guy covered a Paul Gilbert song and did some bending. Now I don't know if it was just poor technique or the TT neck itself, but the bends were out of tune. He also limited himself to extremely shallow, manic mosquito vibrato. Again, I don't know if this was just his technique, or a deliberate attempt to avoid vibrato-ing over the varied fret spacing.

 
Fascinating stuff.
 
My Kemper Profiling Amp uses its built-in pitch shifting software to accomplish something very similar.
 
From the manual:
Pure Tuning
 
When you press "Pure Tuning", intervals produced by the Pitch Shifter will be slightly detuned from the standard tempered scale to create a so-called "natural" or "pure" tuning. This will avoid harmonic beating, especially when distorted afterwards.

• Choose your favourite distorted rig
• Turn down Gain to clean.- Select the Type "Chromatic Pitch" in one of the STOMP slots
• Turn Mix all the way to the left, and Voice Mix to the middle, so you hear both Pitch Shifter voices
• Choose +16 and +19 for Voice 1 and 2 Pitch to get the third and fifth above the octave

 
Sounds crazy, right? The was never a need for such thin sound.
 
Now turn the Gain up for distortion. You will hear a deep growl, swinging around the original base note that you are playing on your instrument. Not too nice.
 
Now press "Pure Tuning", and you will get a nice, steady fundamental note. Even chords might work. It still sounds like your guitar, but different. It doesn’t even sound like a pitch shifter anymore. You can get different colours by choosing different intervals for a solo sound, for example. Be sure to experiment with different interval settings!
 
What has happened?
 
You might be aware that the third and fifth above the octave are natural harmonics (overtones) to the note you play. They both blend with the fundamental frequency, especially when driven by a distortion. However, intervals tuned to a tempered scale do not reflect the overtones exactly, as they are slightly detuned to fit into the musical scales. This results in heavy beating when mixed in the distortion. "Pure Tuning" solves this issue immediately, allowing the pitch shifter to create sonic colours rather than additional voices.

I was under the impression that temperament was different in every key.
In the old days they used to have different "keyboards" for different temperaments
And that is why they invented equal temperature.
 
So with this guitar I need a different necks for Bb, Am, G, F, Em etc????? 

Yes, when I first looked at the frets I was assuming the designer was trying to make a guitar with just intonation, which would seem to require a different guitar for each key. The fret variations look like they may be extreme enough to accomplish that. But the article seemed to indicate it was an attempt to produce a standard (equal temperament) scale accurately.

So since equal temperature is a compromise that enables you to play in all keys, their guitar is a compromise.
Just as my normal guitar (of which they say it is not exactly equal temperature) is a different compromise.
But my normal guitar may be a better compromise for some of the keys.
(That explains the preferance of some forum members for certain keys (such as Am))
