so apparently vai is all into true temperament.
http://www.truetemperament.com/main.php?go=0&lan=1check out these frets. last time i seen a wavy set of frets like that was about a half hour after some smelly hippy gave me a bag of horrible tasting mushrooms to eat in the parking lot of a grateful dead show. jerry garcia's guitar was breathing after that. then i saw jesus, only he didn't look like the pictures of him. he looked like a naked wilford brimley. and he wasn't nice like you'd think, he was irritable and kept telling me that in order to save my soul i needed to eat more quaker oats...
ANYHOO, anybody who's been playing guitar a long time knows that you can never intonate a guitar PERFECTLY. it's always just "close enough". and if you've ever been annoyed that your open E chord isn't perfect, you then tune your open G string to MAKE it perfect, only to discover that now the open D chord is horribly off. the buzz feiten tuning system claimed to fix this, but it wasn't truly a perfect fix. it was more like a work around that mostly kinda worked, but still had problems. (try playing a chord up high on the neck with open strings, NO GOOD.)
this thing apparently fixes the problem totally and makes your guitars intonation perfect all over the neck. but is it worth the cost? the look? if this truly works, will it catch on? will steve vai make it popular? or will we have to wait until korn starts using these necks before all the kidz think it's cool?
