It's safe to say that Korg needs little introduction. They got their start 50 years ago creating some of the world's first synthesizers, and have grown to be one of the true powerhouses of music electronics. They also created the world's first handheld guitar tuner, and their legacy of great, easy to use tuners continues today. In fact, even though Korg has long since discontinued their classic CA-30, I still have several in our shop, and it's still my go-to tuner in most stage settings.
