3 a-side precision locking machine heads

Sperzel tuning keys offer our unique design and precise machining tolerances to eliminate shaft wobble and provide minimum backlash and endplay, 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.

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. The Trim Lok is a mechanical type locking system that can be used on ANY guitar, including non-trem or acoustic.

Here's how Trim-Lok works:
The tuner lock knob is loosened, and the string end is inserted into the hole in the tuner's shaft.

DO NOT REMOVE THE KNOB, AS IT MAY RESULT IN LOSS OF LOCKING PIN AND DESTROY THREADS ON THE LOCKING KNOB SCREW AND WILL NOT PUSH PIN ALL THE WAY UP TO THE LOCK STRING.

The string is pulled much tighter than with a conventional tuner, as the goal is to have approximately 1/4 to 1/2 wrap of the string on the tuner shaft when the string is tuned to pitch. More than 1/2 wrap can create the tuning instability problems associated with multiple string wraps.

While holding the string in place, the locking knob is turned to lock the string in place in the tuner shaft.

The string is tuned to pitch with the tuner button, and the excess string is cut. Repeat these steps with the remaining strings.

You will find that the strings require less "stretching" with locking tuners. This is due to the fact that most of the "stretching" of the strings necessary with conventional tuners is actually "seating" the multiple-string wraps.
