Precautions

Location

Using the unit in the following locations can result in a malfunction. In direct sunlight Locations of extreme temperature or humidity Excessively dusty or dirty locations Locations of excessive vibration Close to magnetic fields
Slide and remove the battery compartment cover located on the back of the GA-40. Insert the batteries ensuring that you observe the correct polarity, and replace the cover. If the GA-40 malfunctions, and you are unable to solve the problem by turning the power off and on again, try removing the batteries and then reinstall them. The included batteries are provided for the purpose of verifying operation and therefore may have a shorter lifetime than usual. When the batteries run low, a battery indicator will appear in the left of the display. When this indicator appears, replace the batteries as soon as possible. Power-off the GA-40 before you replace the batteries.
When tuning an acoustic guitar If you're using a separately sold Korg CM-100 contact mic, connect the CM-100's plug to the GA-40's INPUT jack. If you're using the internal mic, don't connect anything. Press the [STANDBY/ON] button. The GA-40 will be in Meter mode. The power will turn off automatically if the tuner is not used for approximately twenty minutes. Press the [GUITAR/BASS] button to select the instrument you're tuning. The tuning pitches will be as follows. GUITAR: 7B, 6E, 5A, 4D, 3G, 2B, 1E BASS: LB (Low B), 4E, 3A, 2D, 1G, HC (High C) Play a single note on your instrument. The name of the note closest to the note you played will appear in the upper left of the display. Tune your instrument so that the desired note name appears. If you're using the internal mic, position the mic as close as possible to your instrument, and ensure that extraneous background sounds are not picked up by the mic while tuning. While playing a single note, tune your instrument so that the indicator in the center of the tuning guide is lit (if the tuning reference is A=440 Hz). The left indicator of the tuning guide will light if the pitch of your instrument is too low, and the right indicator will light if the pitch is too high. Each step in the meter is approximately 2 Hz.

Power supply

Be sure to turn the power switch to OFF when the unit is not in use. Remove the battery in order to prevent it from leaking when the unit is not in use for extended periods.

Sound Out mode

This mode lets you listen to a reference tone while you tune. 1 Perform steps 2 and 3 of Meter mode. 2 Press the [SOUND] button. The GA-40 will be in Sound Out mode, and the speaker will play a reference tone. 3 Press the [SOUND] button again to select the desired note name. The reference tone is one octave higher than the actual pitch of your guitar, and two octaves higher than the actual pitch of your bass. 4 Tune your instrument to match the reference tone.

Interference with other electrical devices
Radios and televisions placed nearby may experience reception interference. Operate this unit at a suitable distance from radios and televisions.

Handling

To avoid breakage, do not apply excessive force to the switches or controls.
If the exterior becomes dirty, wipe it with a clean, dry cloth. Do not use liquid cleaners such as benzene or thinner, or cleaning compounds or flammable polishes.

Using the stand

By opening the stand located on the back, you can position the GA-40 at a convenient angle.

Flat tunings

In either Meter mode or Sound Out mode, you can tune to a pitch that is between one semitone ( ) and five semitones ( ) below the selected note name. This setting will not be remembered when you turn off the power. 1 Press the [FLAT] button several times to specify how far you want to lower the pitch relative to the note name. 2 Tune your instrument in the usual way using Meter mode or Sound Out mode.

OUTPUT jack Internal mic

Meter mode
This mode lets you tune using the meter in the display. 1 Connect the tuner. The connection method will depend on the type of guitar you're using. When tuning an electric guitar or bass Be sure to use an instrument cable for connection to the GA-40's INPUT jack. You can't use the internal mic if a plug is inserted in the INPUT jack. If you're performing on stage, it is convenient to use the GA-40's OUTPUT jack. Connect your guitar to the GA-40's INPUT jack, and then connect your amp to the OUTPUT jack. The sound of your instrument will be sent from the GA-40's OUTPUT jack to your amp, allowing you to tune or perform while the GA-40 remains connected. If you've connected the OUTPUT jack to your amp etc., you must insert a cable into the INPUT jack. If nothing is connected to the INPUT jack, the internal mic will be automatically used. In this case, sound entering the internal mic could cause feedback, possibly damaging your amp.
