Korg AW2G Chromatic Clip-On Guitar Tuner

Now it's easy to keep your guitar in tune - even during performance. The AW2G clips on to your guitar's headstock and provides immediate tuning information - without interfering with your playing. The display is backlit and reversible, assuring the best visibility in any environment. The unique double ball-joint mounting provides maximum versatility. Highly accurate (+/- 1 cent) over a wide range (A0 - C8) the AW2G can also be calibrated to any reference pitch from 410 to 480 in 1 Hz increments. Energy saving "Auto" mode extends battery life by idling the display lighting when not in use.
