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.
