The right side of the meter display will strobe if the note is sharp, and the
left side of the meter display will strobe if the note is flat. When the pitch is
correct, only the center LED will light up.
The pitch is sharp.
In tune.
The pitch is flat.
Calibration (reference pitch) settings
(*M)
Each time you turn the right shuttle switch upward (or downward), the
calibration value (reference pitch) increases (or decreases) in 1 Hz steps. The
last digit of the setting appears in the note name indicator for a few seconds.
6 (436Hz)... 9 (439Hz) 0 (440Hz) 1 (441Hz) 2 (442Hz) ... 5 (445Hz)
The setting range is between 436 and 445 Hz.
Attaching to the instrument and range of motion
The Sledgehammer Custom 100 tunes by picking up the vibrations of the
instrument. Therefore, be sure to attach the Sledgehammer Custom 100 to
the headstock of your instrument in order to tune it. In addition, the Sledge
-
hammer Custom 100 can be freely moved so that the display is easy to read.
The Sledgehammer Custom 100 may be damaged if you apply excessive force
within its range of motion, or attempt to move it beyond its intended range of
motion.

Please carefully attach the Sledgehammer Custom 100 to your instrument. Leaving
the Sledgehammer Custom 100 attached for a long time may damage or mark the
instrument's surface.
Depending on various factors such as age-related change or the surface finish,
there is a possibility that your instrument may be damaged by attaching this
product.
Shuttle lights
(*M)
As a default, the shuttle lights are set to light up when no note is inputted for
tuning and to go off while tuning.
If you want the shuttle lights to remain off, hold the left shuttle switch turned
upward for three seconds when you turn on the tuner. After the shuttle lights
blink, they will go off.
Repeat the procedure to return the shuttle lights to the setting where they
light up when no note is inputted.

Tuning
Tuning procedure
1. Turn the left shuttle switch upward. Each time you turn the shuttle switch,
the Sledgehammer Custom 100 will be turned on or off.
If the power is left on for approximately 3 minutes without any user input,
it will turn off automatically.
2. If necessary, change the meter mode and calibration (reference pitch).
3. Play a single note on your instrument.
The note name closest to the detected pitch appears in the note name indicator.
Tune your instrument to the correct pitch so that the desired note name
appears on the display.
4.
Tune the instrument by playing a single note and checking the meter.
The tuning indications differ depending on the selected meter mode setting.
Even if the pitch is within the range of detection, it may not be possible to detect the
pitch of an instrumental sound that contains large numbers of overtones or a sound
that has a rapid decay.
The meter may respond to vibrations it picks up from the environment; however,
this will not affect tuning of the instrument.
Setting the meter mode
(*M)
Each time you turn the left shuttle switch downward, the meter mode changes.
A number indicating the meter mode appears in the note name indicator for
a few seconds.
1 (Regular)
→
2 (Strobe)
→
3 (Half strobe)
→
1 (Regular) ...
1: Regular meter
Tune your instrument so that the center LED of the meter display is lit up.
The LED illumination will move from the center toward the right if the note
is sharp, or from the center toward the left if the note is flat.
The pitch is sharp.
In tune.
The pitch is flat.
2: Strobe meter
Tune your instrument so that the illumination stops flowing in the meter display.
Since the strobe meter has higher precision, it allows you to tune with greater
accuracy. The illumination will flow from left to right if the note is sharp, or
from right to left if the note is flat.
The pitch is sharp.
In tune.
The pitch is flat.
3: Half-strobe meter
Tune your instrument so that the stream stops and only the center LED is lit up.
