Independent shopping perspective
The Korena take
KORG’s GA-2 is a compact chromatic tuner for guitar and bass with a large note and string display, needle-style meter, and red/green LEDs. Tune through its built-in microphone or a 1/4-inch TS input, then choose visual Meter mode or Sound Out reference-tone mode. Dedicated Guitar and Bass modes cover 7-string guitars and 6-string basses, while calibration and flat-tuning settings let you match the tuning setup at hand. Its sliding body gives direct access for battery changes.
