A needle-style meter with large high-visibility note name and string name
KORG's needle-style meter that shows you the pitch quickly and accurately now has a note name and string name display area that's approximately four times larger, making it easier than ever to read. Red and green LEDs to indicate the pitch discrepancy are also provided for even smoother tuning.
A compact body that's slim and lightweight
The GA-2 is a pocket-sized card-type tuner that's easy to carry anywhere. The rounded body is comfortable to hold in your hand, and has an even more stylish design that accents the battery compartment. It uses a new mechanism that lets you replace the battery by sliding the entire body, so there's no risk of losing the battery compartment cover.
Dedicated guitar and bass modes
The GA-2 lets you select either Guitar mode or Bass mode for truly easy operation with automatic pitch detection. The guitar mode supports 7-string guitars (7B through 1E). The bass mode supports 6-string basses (Low-B, Hi-C). A high-sensitivity microphone is built-in, allowing easy and accurate tuning of acoustic guitars.
Quinta Flat tuning mode
The GA-2’s Quinta Flat Tuning mode supports the lowered tunings used in heavy metal styles to give more weight to the sound. The GA-2 gives you five steps of flatted tuning, extending as far as five semitones below standard pitch, and supporting even super-long scale guitars that are five frets longer than conventional guitars.
Tune with adjustable calibration
Since the calibration value of 430–450 Hz is shown within the meter, you can tune using the calibration of your choice.
Sound mode emits a reference tone from the built-in speaker
In addition to tuning visually with the meter, you can also tune by ear using Sound Out mode which emits a reference tone to which you can tune each string of your guitar or bass.
Approximately 200 hours of continuous use
The high-efficiency long-life design allows approximately 100 hours of continuous operation on two AAA zinc-carbon batteries or approximately 200 hours on alkaline batteries.
