Korg GA Custom is a 3D visual tuner from the Custom Shop series. The clearly visible note display and the movement of the brightly lit LED make the tone different, and the change can be recognized immediately. This new 3D visual instrument can be easily adjusted to a precision of ± 0.

GA Custom by KORG is designed for professional users and can provide extremely precise tuning with a detection range of +/- 0.1 cents, which is a level of precision that is not available in compact tuners.

With GA Custom, guitarists of all styles can now enjoy the same ultra-high precision as KORG's flagship tuner, Pitchblack Pro.

It provides three display modes: normal, strobe, and semi-strobe. Each mode can be easily selected according to the user's preferences. The strobe light and semi-strobe light reflect the extremely high precision of GA Custom, making the adjustment extremely convenient.
