I know this has been asked before but what method/s do you all prefer to intonate/tune your guitars and why? I'm currently having a hard time trying to get the intonation and tuning right on one of my Grosh strats. For what it's worth, the guitar is set up properly (nut, relief, action & pickups etc) except for intonation at this point. The trem is against the body for downward action only with three springs. I'm very sensitive to intonation being off - chords, 4ths, 5ths - especially in the higher registers (12th fret up). Now I've played many guitars both old and new where they just sounded beautifully in tune and intonation spot on over the entire fretboard (without the Buzz Fieten system installed). At first I used the common open string/12th fret intonation method and then used the Peterson "guitar" preset to tune up - good but not good enough. Chords above the twelfth and 3rds, 5ths still sounded slightly off. I then tried a method explained on the Peterson forum where you intonate the 5th and 17th frets on all strings and then tune up using equal temperament (or sweetened guitar preset) and tune all the A notes on the fretboard. Peterson claimed this is the best compromise and yields "extraordinary" results. MY results were less then stellar and I couldn't really hear any real improvement over the first method. Are there any other ways/methods you guys use to arrive at better results? If so, I would appreciate if you could elaborate on the details and share your "secrets"
