Sperzel Trim Lock tuning keys are machined from solid billet aluminum and designed to provide stable performance and reliable action. These light-weight, precise tuners don't require multiple string wraps and eliminate the age-old tuning problem of the strings seating during play. The housing on Sperzel tuners extends further up the shaft with the bushing threads on the outside, keeping the string post solid and eliminating wobble.
This set is lightly used and includes all hardware necessary for installation on your guitar. Please contact us if you have any questions about these tuners.
