Sperzel 3 + 3 Trim-Lok Machine Heads Satin Chrome

Sperzel 3+3 Trim-Lok tuning keys offer our unique design and precise machining tolerances to eliminate shaft wobble and provide minimum backlash and end play, which greatly reduce your guitar's tuning problems. Our housing extends further up the shaft with the bushing threads on the outside, keeping the string post solid.

The Sperzel 3 + 3 Trim Lok is the ultimate in tuning keys. The locking feature eliminates the need for multiple string wraps, and trem users no longer need a locking nut that deadens string sustain and all annoying Allen screws and wrenches (added weight). Tired of tying strings? This is the answer. This model is proven to hold strings tightly, allowing the guitar to stay in tune to improve playing enjoyment. The Trim Lok is a mechanical type locking system that can be used on ANY guitar, including non-trem or acoustic.
