A: When you have the Buzz Feiten Intonation System installed on a guitar or a tapping instrument, your playing will sound more ‘in tune’ than on a normal guitar. But does it require some special way of tuning up?
Not really. Of course, the better you tune up, the better you will sound. However, the Feiten system is installed by making small adjustments to string length at both ends of the strings. On one end, the nut (or zero fret) is moved slightly. On the other end, the string saddles are adjusted to +/- a few cents here and +/- a few cents there.
The result is kind of like the ‘stretch tuning’ commonly used on pianos to make them sound more ‘in tune’ to our ears. Pianos have used this advanced ‘stretch tuning’ system for 700 years. But guitars never had such an adjusted tuning until Buzz Feiten, a southern California studio musician, developed the system.
A guitar has to have adjustments in two dimensions. Adjustments *along* the length of the string, and adjustments *across* the strings (one string against another). It’s not a perfect system, but it sure sounds a lot sweeter than no system at all!
Because the adjustments are already done, at both ends of the strings, you can tune up any way you wish.
So tune up using any method you like — tuner, ear, harmonics, beats — and it will sound better than a normal guitar, because the string saddles have offsets, and each string is biased a little against the other strings. There is a suggestion in the Mobius Megatar Owner’s Guide for one way to tune up, but you can tune it any way you wish, and it will sound more ‘in tune’ than would a normal guitar tuned up in the same way
