- Basic needle-style meter lacks the backlit or color-coded visual feedback found on some competing tuners
Frequently Asked Questions
Can the Korg GA-2 tune instruments other than standard 6-string guitar?
Yes, it supports 7-string guitars (7B through 1E) and 6-string basses (Low-B through Hi-C), and its chromatic mode can detect any pitch, making it usable for other instruments as well.
What is the Quinta Flat Tuning mode on the GA-2?
Quinta Flat Tuning allows you to tune your guitar down in half-step increments up to five semitones below standard pitch, which is useful for players who use drop tunings or need to match alternate tuning setups.
How does the GA-2 detect pitch — does it need a cable connection?
The GA-2 has a built-in high-sensitivity microphone for acoustic instruments and also accepts a 1/4-inch input cable for electric guitars and basses, giving you flexibility in how you connect.
Can I adjust the reference pitch on the GA-2?
Yes, the calibration is adjustable from 410 Hz to 480 Hz, so you can match orchestral tuning standards or any non-standard reference pitch your situation requires.
What do the pure major/minor third indicators do?
These indicators show you when a major or minor third interval is in tune according to pure (just) intonation rather than equal temperament, which is helpful for achieving smoother-sounding chords.
