Re: Blog: Unlocking The "Secrets" of Intonation
This is one of the topics that I always end up feeling puzzled about. If everything else is perfect, is new technology (like an Earvana nut or other) still needed?
If you have:
- A straight neck
- Level, correctly placed frets
- Strings that are broken in but not corroded
- A well cut nut
- A correctly intonated, correctly placed bridge
- A pickup that doesn't have magnets so strong that it causes stringpull
- Correct technique
... Is intonation still a noticeable problem? I know that's a lengthy list, but I find that with most guitars, at least one or two of those things can be improved.
All this does is make the most of an instrument that still has a deeply flawed intonation system. You might set your guitars up the way you want them, tune them "properly", and all that, and play for years and years without ever noticing anything wrong. But there will still be chords on that guitar that are never in tune. If you don't use them, it won't matter.
Some players, though, find that certain intervals on their guitars, played in certain places, sound really sour to them. Even when the normal things are "right", this can still happen. The reason is because of the compromises inherent in the way guitars are conventionally built, intonated, and tuned. It's impossible to have every note on every string perfectly in tune with every note on every
other string at the same time.
Some of the intervals, on the normal system, are right on. The open strings, the twelfth frets, the usually calibration points, those are likely to be on. Others are a little off but close enough that they usually work okay. Still others are pretty dissonant, if you intonate and tune the "normal" way. Again, if you don't use them, why would you care? If you do use them, you likely adjust for it in the last phase of tuning so that you "sweeten" those intervals a little compared to the usual way.
These newer systems -- everything from Earvana and Buzz Feiten to Fretwave and fanned frets -- try to improve on the conventional system by breaking out of the mold of treating every string the same at the fretting end. Some of these are more radical than others, but they all try to get more of the guitar's notes more in tune at the same time.
Do we need it? I don't think anyone
needs it, but how do you define a need in a hobby/industry where we generally do things because we
want to do them? Are some people going to try it and say, "Pffftt... who cares?" Sure. Are some people going to try it and feel it adds something worthwhile for them? Sure.
