Models/Colors
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.
All guitar models are easily reversible, allowing conversion to
left-handed or custom configurations. Sperzel has been
manufacturing staggered string posts since the late 1970s,
allowing for better pull through the nut and reducing the use of
string trees on six-in-line guitars with flathead stocks.
Guitars with tilt-back head stocks use all one post height; our
years of experience will help you determine the height you need.
This is important to know when ordering the correct set of keys
for your guitar - staggered for flat; non-staggers for
tilt-back.
Our unique design allows you to choose the style of housing (or
body), Enclosed or Open Back, and also what model string post,
Trim-Lok, Sound-Lok or Solid-Pro, is right for you. Custom
builders welcome.
All Sperzel tuning keys can be assembled in either body (housing)
style:
Enclosed Housing
Open-Back Housing

Trim-Lok
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 KNOB, 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.
NOTE! 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.

Sound-Lok
This is a more friction-passive positive locking system which
still eliminates multiple wraps around the string post. Usually
a 1/2 to a full wrap locks the string tightly, improving tuning
stability for any kind of guitar. |
Here's how Sound-Lok Works
The Sound-Lok tuner is a friction lock system, and has the
look of vintage safety posts of the past, where you had to
measure the string and cut to length. This was very
time-consuming and wasteful, especially if you cut the string
short.
The Sound-Lok needs no measuring; simply insert string into
the hole by the slot and feed string all the way through the
shaft until it comes out the bottom of the post. Pull the string
until tight, then bend the string so it lies in the slot on top
of the post. With your thumb holding the string in place, tune
to pitch with tuner button (Approximately 1/2 - 1 full wrap is
required). The string will automatically grab and lock into
place. Cut any excess string and repeat for remaining strings.

Solid-Pro
This is our non-locking model that requires tying and winding. It
incorporates all the precision machining in a traditional style.
You can feel the solid integrity. This key was featured on the
25th anniversary Strat. |
 |
Bass Locking Tuners
The same unique design and machining as our Trim-Lok tuners in a
bass model, eliminating the need for multiple wraps around the
string post. Our bass tuning keys will fit in a 7/16" hole in head
stock. |
 |
The "D" Thing
A Universal replacement unit drop tuner that is easy to install
and simple to use. No big bulky contraption to mount, D Thing is
integrated into the tuning key. |
Sperzel offers a number button shapes and finishes to choose from
and also comes in colors
(From left to right): No. 1, No. 2, No. 5 & No. 6
Dare to be Different: Anodized Colors and Satin Finishes
All Sperzel tuning keys are available in many colors and
combinations to individualize your guitar. Break away from
traditional plated finishes. In reality, the anodized finish is
better for the integrity of the tuning key because it is etched
into the components and does not affect tolerances and is more
environmentally sound. Plating is a coating and is not
environment-friendly.
