The AW2 from Korg is a chromatic tuner that is designed to clip directly onto an instrument. It picks up sound with either its built-in microphone, or its vibration-sensing Piezo sensor (which is useful in noisy environments). It runs on an included CR2032 lithium battery (which are easy to replace) for an impressive 150 hours. If you forget to turn off the AW2, it will automatically power itself down to save energy.

It comes with two instrument clips (one large, one small) that make it possible to attach the AW2 to a large variety of instruments. Because different kinds of instruments have different bodies and different tuning "sweet spots," the placement options of the AW2 is an important feature. A built-in double ball-joint allows you to position the AW2 in many different angles.

The AW2 features a wide tuning range of A0--C8. Special markings indicate pure major and minor thirds that are relative to a specific pitch. The display is backlit, making it easy to read in any setting. The light can be dimmed, turned off, and set to only get bright when a signal is detected.
