Korg CA-50 Tuner

The CA-50 features high-precision tuning functionality and a slim and compact design. The new CA-50’s display is now, even easier to read. Long considered the standard in chromatic tuners, the CA-50 offers simple and intuitive operation and a satisfying tuning experience for every instrumentalist.
The LCD screen of the CA-50 shows a needle-type meter to quickly and accurately show the pitch, and provides a note name indication in the middle of the display. The note name indication is now larger and even easier to read. This ensures simple and smooth operation even for beginners.
The calibration function supports a variety of concert pitches. It can be adjusted in 1 Hz units in the range 410–480 Hz, allowing flexible tuning that matches the song or key.
The CA-50 features a detection range of A0 (27.50 Hz) to C8 (4186.01 Hz). For wind instruments from piccolo to tuba, or string instruments from violin to contrabass, you can tune band or orchestral instruments of any pitch range. A high-sensitivity mic is built in, allowing the note name to be detected accurately even without a contact mic. By using the separately sold CM-200 contact mic, you can tune with confidence that nearby sounds will not affect the result.
The meter scale of the CA-50 provides marks that indicate pure major and minor third intervals. By tuning to these marks* you can play beautiful harmonies when you're in an ensemble. This is convenient not only in a brass band or orchestra, but also for vocal or a cappella practice.
