Please note - the height of the posts are all measured from the centre of the string hole to the base of the string post.
Sperzel Locking Tuners Feature:
The Trim-Lok feature is a mechanical type locking system, which eliminates the need for multiple string wraps.
Here's how Trim-Lok works - Unscrew the locking knob until the locking pin inside the string post clears the string hole.
DO NOT REMOVE THE KNOB, AS IT MAY RESULT IN THE LOSS OF THE LOCKING PIN AND YOU MAY DESTROY THE THREADS ON THE SCREW.
To restring your guitar with Sperzels, you first pull the string all the way through the post until tight and then tighten the thumb until the string is locked in place. Do not over-tighten; finger tight will do. Then, tune the string to pitch (Approximately 1/2 turn with tuning button). Now you're in tune, cut the excess string and repeat the process for the remaining strings.
REMEMBER, there is NO TYING or WINDING of the string with the Sperzel Locking Tuners.
