Sperzel Nickel Sound Lock Tuners, 3 x 3

These hard to find nickel-plated sound lock tuners feature an open back housing for a truly vintage look. Sperzel Sound Lock tuners use a friction locking system for lightning quick string changes. Simply insert the string into the hole by the slot, pull the string taut and tune to pitch. The string stays tightly locked in place, eliminating many of the tuning problems of a traditional tuner. These tuners are machined from solid billet aluminum, making them light-weight.

The pin-mount installation doesn't require the use of screws, and the packaging includes a convenient template for correct positioning of the holes for the pins.
