All Anderson guitars are equipped with the Buzz Feiten Design Tuning System. The Feiten system is primarily a visually undetectable structural neck change in combination with slightly altered bridge intonation offsets. It allows your guitar to tune more accurately than you have ever experienced before. The most noticeable benefit is that chords sound more in tune with each other. The method shown below is a slightly more precise method of tuning which will allow you to take full advantage of this new technology. But don't worry, even if you tune using your old standard way, your guitar will still tune and play more accurately than ever before.
Remember one thing, even though this tuning system is much better than anything any of us have ever heard, it is not perfect, no tuning is. But, your guitar will now be as accurate as a well tuned piano. This piano type tuning is called "Well Tempered Tuning." It is a compromise in tuning where everything sounds pleasing, as opposed to "Even Tempered Tuning" where a couple of things sound perfect while everything else sounds "out." When an instrument that is designed to play chords is tuned normally, or "even-tempered," it will produce some intervals between notes that sound perfect and others that sound quite out of tune, especially 3rds and 6ths. For centuries artists have realized that if a keyboard were tuned using a "well-tempered" scale, all of the chords would sound pleasingly in tune. Although the guitar is also an instrument capable of playing chords, that same method was not applied to the guitar until Tom Anderson introduced the Buzz Feiten Tuning System in early 1996.
The bridge intonation has been set at the factory and should not need to be readjusted, unless changing string gauge by two or more sizes (i.e.009 to .011). A bridge intonation adjustment does require an extremely precise tuner. We are now using the Sonic Research Turbo Tuner for tuning and intonation. We use a bench tuner that has many programming parameters, but they make the ST-300 which is user programmable to accept the Buzz Feiten offsets. It is the fastest, most accurate tuner we have seen and it will radically simplify your live tuning experience.
