A Sleek, Feature-packed Guitar Tuner

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 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.

You’ll appreciate these exciting new features

You can find Korg’s GA-40 in gig bags all around the world. Musicians have long valued its high-precision, LCD needle-type metering and flexible operation. The GA-50 improves upon its forerunner’s design in many ways. Its display features larger note name indicators, making it a breeze to read. A new mechanism prevents the tuner from overturning, making it less likely to slide off your music stand. Beyond that, its battery life has been increased to up to 135 hours. At City Music, we appreciate the GA-50’s impressive price-to-performance ratio — you get a lot of tuner for not a lot of money.
