LCD needle Style chromatic tuner. All-in-one functionality. Ultra compact. Up to 200 hours of battery life! Pitch reference tone and marks for pure major thirds and minor thirds.

Wide range of pitch detection for any instrument

The CA-2 supports a broad range from A0 to C8, allowing speedy and high-precision tuning of wind, string, keyboard, and other instruments.

In addition to the high-sensitivity built-in microphone, a separately sold CM-200 contact microphone can be used to send the vibrations directly to the tuner for even more accurate tuning.

The 1/4″ jack input can also be used to connect directly to your electric instrument for highly accurate, or near silent tuning.
