Has anyone actually tried a microtonal guitar? My instinct tells me that while it might be perfectly in tune in some keys, in others it will sound terrible.
Excellent question! Theoretical advances are one thing, real implementations are another. While the movable microtonal frets make some sense to me, (player can adjust for the key, intonation, strings ) the fixed fret version does not make sense to me. I'd like to play it and see for myself... willing to let it convince me in reality.

I like to keep an open mind and would like to try one before making any comments or jokes about it.

Pretty standard fare currently for some electrics, especially 7 and 8 strings.

I have played an electric with individual fret compensation, i.e., wiggly frets. Stretches are mildly weird to get used to, but work just fine. My concern initially was that a stretch would terminate at a transition point of two wiggles. But in use, that did not happen. I did not buy that instrument.

My main issue is that, as someone above said, you are stuck with the same type of strings or all the wigglyness is useless.

What interests me is how to make them. How do you cut the channel? I can see how you could bend and squish the fret material after careful measurements. Then when you need a fret job, oh my! The cost might be something to consider. And on an electric with lots of stretches, you will wear out the frets sooner rather than later.

An awful lot of what wears frets out on electrics is string bending / side-to-side vibrato etc.

Try vibrato on a true temperament guitar while listening to what it sounds like. You won't be doing it for much longer I'll wager.

Some of the available wiggly frets are cast to shape; they probably work like a staple. You could, of course, use small staples for each string, plugged into properly spaced holes.

One of the big advantages of Equal Temperament is that all of the semitones are the same size in terms of cents. This allows you to use straight frets. If you're using wiggly frets you're not playing in ET. That's not a problem if you only play solo and like the way it sounds. If you're playing with other folks you can run into all sorts of dissonance.

I saw a very high end guitar on e - b a y several months with frets like this. Don't recall the name but I think the price was about $20 K.

How are you supposed to play barre chords with that, especially at the 3rd fret?

Frank
I suppose with an electric guitar you can get away with a very small amount of buzz. Less so on a classical. I certainly think it makes playing buzz free barre chords pretty tricky at frets 1 and fret 3. Of course those frets tend to be used a lot but it would be interesting to hear from someone who has played a very wiggly fret classical.

I like very much the link that u gave us. Many many Thanks. I read something about John Schneider microtonal guitar and Turkish microtonal guitar music, and it become very interesting to me. Makes perfect sense, if we want some sort of deep contact with music, to find our notes. Nature, the way I see it is not perfect, there is always some sort of imperfection to add that extra beauty to it. I mean, why the frets have to be so mathematical exact, it's boring. There must to be another way. This is how I assume it, I am just an amateur by the way, but I will experiment at least with a fretless guitar to feel how it looks and sounds like. thanks

Referencing my Rodriguez FF Sabicas - I was talking to a Bay Area luthier, Lewis Santer, a protege of Ervin Somogyi. That school of thinking indicates "another way" as you put it. He pointed out that the bridge on my Rodriguez is actually in the wrong place, and if you follow the math, you cannot properly intonate that guitar. Lewis then pointed out that the Rodriguez sounds fine because they ignore the math, and set it up for best musicality based upon artful consideration of the many factors that defy clean mathematical precision. This can be called "artistry", or the way I think of excellent lutherie, "craftsmanship at the level of art."

As a pragmatic exercise, if you measure the intonation on that guitar, it's wrong. But if you play that guitar, it all works out quite well with overall musicality across the length of the fretboard. Now, "boring" is a loaded term. It could be "not boring" in a bad, worst possible kind of way. And say what you want about a factory guitar, but the luthiers at Rodriguez got the FF Sabicas right by ignoring the exact math.

Having said all of that, I trust the math of scale length and intonation on well build guitars, and would not trust "artistry" to ensure excellent intonation consistently. It also helps greatly to be less fussy about perfect intonation! :D

I sinmply don't have arguments to counter your exposition, maybe one day I'll have, not now. But anyway many thanks for the elegant and clarifying reply.

We would all need a set of wiggly capos.
