The KORG GA-2 Guitar/Bass Tuner combines trusted accuracy with a refreshed, easy-to-read design, making this compact guitar tuner a reliable everyday tool for players. Its enlarged note name and string name display—now approximately four times larger—works alongside KORG’s precise needle-style meter and red/green LEDs for fast, clear pitch indication whether you’re tuning at home, in the studio, or onstage. Dedicated Guitar and Bass modes support 7-string guitars (7B–1E) and 6-string basses (Low-B to High-C), while a built-in high-sensitivity microphone and 1/4" input provide flexible tuning for electric and acoustic instruments. Quinta Flat Tuning mode allows down-tuning up to five semitones for heavier styles, and adjustable calibration from 430–450Hz ensures compatibility with a variety of performance settings. Players can tune visually in Meter mode or by ear using Sound Out mode with the built-in reference tone. Compact and pocket-sized, the battery-powered KORG GA-2 tuner runs on two AAA batteries for up to 200 hours and features a sliding body design for easy battery replacement. The result? KORG precision in a sleek, portable guitar and bass tuner format.
