Parts of the Sledgehammer Pro
Installing the battery
- While lightly pressing the part marked A, pull the battery holder in the direction of the arrow to slide it out.
- Making sure to observe the correct polarity, insert the battery so that the “+” side of the battery is visible.
- Return the battery holder to its original position.
Tuning
Tuning procedure
- Turn the left shuttle switch upward. Each time you turn the shuttle switch, the Sledgehammer Pro 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.
- If necessary, change the meter mode and calibration (reference pitch).
- 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.
- Tune the instrument by playing a single note and checking the meter.
- The tuning indications differ depending on the selected meter mode setting.
*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) …
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
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.
Half-strobe meter
Tune your instrument so that the stream stops and only the center LED is lit
up. 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
*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 Pro tunes by picking up the vibrations of the instrument.
Therefore, be sure to attach the Sledgehammer Pro to the headstock of your
instrument in order to tune it. In addition, the Sledgehammer Pro can be
freely moved so that the display is easy to read. The Sledgehammer Pro may be
damaged if you apply excessive force within its range of motion, or attempt to
move it beyond its intended range of motion.
