Buzz Feiten has been a professional guitarist since 1967 and has recorded and toured with a wide variety of artists (see discography). In 1992 he invented the Buzz Feiten tuning system™, a revolutionary redesign of the intonation process for guitar, allowing the guitarist to play pleasantly in tune anywhere on the fingerboard, regardless of chord shape.

Some of the artists currently using the Buzz Feiten tuning system™ include: Joe Satriani, Steve Vai, Larry Carlton, Robert Fripp, Adrian Belew, Pete Anderson, Liona Boyd, "Dimebag" Darrell (Pantera), Jennifer Batten (of the Jeff Beck group), Mick Mars, Michael Landau, Tim Pierce, Dean Parks, Jackson Browne, David Crosby, Stu Hamm, Jimmy Haslip, and many others.
