I played a Feitenized Les Paul and I've never heard more pleasing open chords in my life. It was night and day for me. It almost sounded too good and sounded fake! I also have experimented with a zero fret on my tele. I just stuck an unused fret by the nut and tuned it up. I noticed instantly how much better everything sounded. anyhow, I have a tele with three barrel saddle. That's not good for intonation from any compensated system. I want to keep my stock saddles. From what I read, both of these nuts will improve the intonation of the first few frets. That's where most of my frustration is. I'm looking for any suggestions and experiences, especially with a tele's bridge involved. Or just what you think of the BF or Earvana thing.
