High-precision tuning in a sleek, feature-packed design — that's what you get with the Korg GA-50. Its predecessor, the GA-40, has been a top-selling guitar tuner for many years. The GA-50 builds upon that legacy, while adding a more readable display, improved battery life, and a mechanism to prevent the tuner from sliding off of your music stand. You also get all of the great features you've come to expect from Korg, such as a wide detection range, an onboard speaker, a built-in reference tone, and memory backup. If you play guitar or bass, the GA-50 is an excellent portable tuning solution.
