With a size similar to an audiocassette case, the KORG CA-1 chromatic tuner features a distinguished design in a pocket-sized package. With a stand on the back, you can place it on any surface. Thanks to the CA-1's broad tuning range, you can tune an array of different instruments, including many keyboard, string, and wind instruments. Pitch and range are quickly detected with accuracy. A built-in, high-sensitivity microphone can detect the pitch of an acoustic instrument — whether it's guitar, bass, mandolin, or ukulele, to name a few — without the need of a clamp or any other equipment. The instrument tuner's large display window also offers greater visibility than many tuners on the market. The display includes an LCD needle-style meter, as well as red and green LEDs for utmost accurate tuning. The auto power-off function saves the battery, even if you forget to turn off the chromatic tuner.
