Sperzel has been manufacturing tuning keys since 1977 with their unique design and precision machining ability which recognized in (Guitar Player Magazine October 1979) as the most significant advancement in guitar tuning capabilities.)This was the beginning of addressing the problems that have held guitar players captive for years.

In 1983, Sperzel introduced the guitar world to a locking tuning key, Trim-Lok that held the string tight without tying or multiple wraps around the string post that can slip and cause staying in tune problems. Trim-Lok also has graduated post heights eliminating use of string trees, locking nuts or any other string deadening device.

Sperzel has put their name on every tuning key since 1977. An American Original.
