Korg AW2G Clip-On Chromatic Guitar Tuner (White)

The white version of the Korg AW2G Clip-On Chromatic Guitar Tuner is designed to clip directly onto the headstock of a guitar. 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 easy to replace CR2032 lithium battery for up to 150 hours. If you forget to turn off the AW2G, it will automatically power itself down to save energy.
