Re: True Temperament Frets
Maybe my ear is underdeveloped, but I'm just fine with straight frets. I can hear when certain chords are a little out of whack if your intonation is off, but if you intonate your guitar correctly, there really isn't a problem.
Also, I firmly believe that in a band setting you'd never be able to tell the difference. I also believe that things actually sound little off if they are too perfect. I bet that on a recording, if I could tell at all, I'd think that the true temper guitar would sound less organic and thinner. I can't make that claim with 100% confidence though, as I've never done the comparison.
All in all, it is an interesting idea, but I'm just fine with straight frets.
Edit: after going through their website and pricing out a neck... double no thanks. I know it must take a lot of time to do, but I just priced a neck out optioned as I would like it and it came to $825. Wow.
