Korg GA-2 Guitar/Bass Tuner

KORG's GA-2 tuner combines precision engineering with practical design, featuring a needle-style meter that provides quick and accurate pitch readings alongside a dramatically enlarged note name and string name display area. The display is now approximately four times larger than previous models, making it significantly easier to read during tuning sessions. Red and green LEDs indicate pitch discrepancy for smoother, more intuitive tuning operations.

This pocket-sized card-type tuner boasts a comfortable rounded body with a stylish design that highlights the battery compartment. The innovative sliding mechanism allows for complete battery replacement without the risk of losing small compartment covers, addressing a common frustration among musicians. Its compact form factor makes it ideal for musicians who need reliable tuning capabilities on the go.

The GA-2 offers dedicated Guitar and Bass modes with automatic pitch detection for straightforward operation. Guitar mode accommodates 7-string instruments from 7B through 1E, while Bass mode supports 6-string basses including Low-B and Hi-C tunings. A built-in high-sensitivity microphone enables accurate tuning of acoustic guitars without additional connections.

For heavy metal and alternative tuning applications, the GA-2 includes Quinta Flat Tuning mode with five steps of flattened tuning extending up to five semitones below standard pitch. This feature supports super-long scale guitars that are five frets longer than conventional instruments, making it suitable for extended range and down-tuned applications popular in modern metal genres.
