Sperzel 6 In Line Closed Locking Tuners

Sperzel Staggered Post Configuration all mount to the headstock via 1-Pin. All Sperzel tuners are REVERSABLE - Can be used on both right-handed and left handed guitars

Note - the height of the posts are 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 that eliminates the need for multiple string wraps. You can use Sperzel Locking Tuners on ANY guitar, including non-trem or acoustic.

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.

Insert the string into the hole and pull the string all the way through the post until tight all whilst holding the string screw locking knob in until the string is locked to the post. 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.

NOTE! When you are installing the staggered post height sets, there are two short posts, two medium posts and two long posts. Start with high "E" string and work back towards low "E."

The short post ---------- High E & B strings

The medium post ------ G & D strings

The long post ----------- A & Low E string

Rule of Thumb: You always start with the shortest post furthest away and longest post closest to the nut.
