  Welcome!

Bob Sperzel explains: "Our research and dedication to producing special machine heads was achieved."

We are proud Sperzel Tuning Keys are used throughout the world and are considered by many to be the best. A product of the USA, competing with international brands, they are referred to as made the American way.

Sperzel tuning keys consists of advanced design standards. Every component is designed to provide stable performance and reliable action during combined movements. Our standards do not allow loose or floating components that are evident with older, traditional stock tuning keys. Eliminating age-old tuning problems and improving tuning capabilities was recognized on the back cover of the October 1979 issue of Guitar Player magazine, where it was described as "the first significant advance in guitar tuning capabilities."

Your ultimate performance is a reflection of the freedom to be yourself!

Thanks!
Bob Sperzel


 

Our tuning keys are machined from solid billet aluminum for light weight and held to precise tolerances and quality checks to produce a precision tuning key that eliminates shaft wobble, endplay and minimum backlash. Our Trim-Lok model offers no tying or winding around string posts, greatly improving your tuning capabilities for playing style and enjoyment. Rid yourself of Tuning Torture Syndrome!

Aluminum also allows us to offer a wide range of anodized colors in solids or combinations. Anodizing is a very durable finish that does not affect the integrity or precision of the tuning key.

Break out of the old 1918 mold age and step up to the New Age machine heads!
