Sperzel 3x3 Trim-Lok Set Machine Heads L3+R3 w/ BONE PEARL Style Buttons - CHROME SATIN
This 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.
