The Korg CA-50 Tuner 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 CA-50 can be used for approximately 135 hours (when using zinc-carbon batteries). When the remaining battery capacity runs low, the display shows an indicator, letting you know that it's time to replace the batteries. A new mechanism reduces the possibility that the unit will overturn, making it less likely that the tuner will slide off and fall when placed on a music stand. You'll be able to concentrate on your playing without fearing that the tuner might fall during the performance.
