Korg Chromatic Tuner Ca 30 By numero9 on Nov 06, 2007 - Updated Oct 15, 2011

The Korg Chromatic Tuner CA-30 is known as the small standard for those musicians wanting an accurate tuning of their instrument without over-simplification of just a note name display and the preference of a needle. For only about $10, this tuner fits in your pocket and works with anything that produces a tone. Furthermore, you can calibrate it to get your tuning just to your wants and needs. The CA-30 has a built in microphone for acoustic instruments and even voice, and a line-in input for electric guitars and other instruments of that ilk. The digital needle display is handy, as it shows precisely how sharp or flat the tone is, and the unit lights up when it's in a good midrange or when it is either sharp or flat. I recommend this to any musician, old and new, for keep their instruments in top tuning.
