Adrian Belew

What's the buzz about? Perfect intonation. With the Buzz Feiten Tuning System every note, every chord will be in tune across the entire fretboard. A fundamental requirement but something guitarists have never had until now.

Gary Burnette

It increased my efficiency in the studio by 30 percent, because I don't spend all that time messing with my tuning.

Liona Boyd

For as long as I can remember, the guitars that my fellow classical guitarists and I have played always sounded slightly out-of-tune and I just assumed that tuning our instruments was always a matter of compromise - that they would never sound perfectly in tune in the upper frets if the open strings were in pitch. Having recently discovered Buzz Feiten's amazing system, I realize that what I had always believed is untrue. A guitar can be in tune in any fret! I would highly recommend his revolutionary approach to guitar tuning for any performer or builder, no matter what style. It will change your life.

Pete Anderson

Long overdue and overlooked, this system has finally made the guitar in tune from top to bottom. Radical bends and steel licks above the 12th fret have never sounded sweeter. I no longer have to fight pitch!

Stu Hamm

Amazing, it really works! from the 1st fret on my low E to the 24th fret on my high G, the bass is finally in tune. Having the 1st four frets in tune (not sharp) has made my life in the studio much easier. I'M SOLD!
