Product Description for the Korg AW-2 Clip-on Tuner

In spite of their light weight and ultra-small size, the AW2/AW2G boast a broad tuning range of A0--C8 and a full complement of solid tuning functionality. A vibration-sensing piezo pickup is built in to the chromatic tuner, ensuring stable tuning even in a noisy environment. You can also tune using the internal mic. In addition, when using the AW2/AW2G in a vertical position, you can use Korg's proprietary Meter Reverse function to switch the meter so that its High (+) indication is upward. The chromatic tuner is powered by a widely available CR2032-type lithium battery, and with the backlight off, the battery life extends to an amazing 150 hours. Numerous other functions are provided, including adjustable calibration to support various concert pitches, auto power off, and memory backup.

Inaccuracies of the harmonies in a triad are particularly easy to notice when playing in an ensemble such as a brass band or orchestra. By slightly adjusting the pitch of a major or minor third relative to the equal-tempered interval, a beautiful-sounding pure third can be obtained. The meter scale of the AW2 includes markings to indicate pure major and minor thirds relative to a specified pitch. Simply by tuning your instrument to these markings, you can perform beautiful, pure harmonies when playing in an ensemble.

The sweet spot that will pick up the sound most effectively varies between instruments - the neck or bell of a wind instrument, or the head or tailpiece of a string instrument --- and the shape of the attachment location differs accordingly. As with the AW1, the AW2 comes with two clips (one large, one small), so you can choose depending on your situation or preference. The large clip is ideal for various wind instruments or string instruments, and the small clip is perfect for use on the thin bell region of a trumpet or trombone.
