Description Technical Specs
 

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 Trim-Lok is a mechanical locking system. Unscrew locking knob until locking pin inside string post clears string hole.

DO NOT REMOVE THUMB LOCK AS IT MAY RESULT IN LOSS OF LOCKING PIN AND DESTROY THREADS ON LOCKING KNOB SCREW AND MAY NOT SCREW ALL THE WAY IN TO LOCK STRING POST. THIS WILL VOID WARRANTY!

Now, insert string into hole and pull string all the way through post until tight, while holding string screw locking knob in until string is locked to post. Do not over-tighten; finger tight will do. Then, tune to pitch (Approximately 1/2 turn with tuning button). You should be in tune; cut excess string and repeat the process for remaining strings

Remember there is no tying or winding of the string on the Sperzel Trim-Lok, which stabilizes tuning. There is less stretching of the string because you have taken the slack out by pulling tightly when starting. Also, string does not have to seat itself.

When installing 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: Always start with the shortest post furthest away and longest post closest to the nut.

 

Please, also be aware that for simplicities sake, we've called the "Satin Chrome" options in the custom section "Satin Chrome" - this isn't actually 100% accurate, as the Satin Chrome models come with Gloss Chrome Thumb Wheels and Stems - but we've kept the naming conventions to stop everything getting confusing when you get into the custom build side of things.
