The AW-1 was a top--selling model that has been popular with musicians of wide-ranging genres for its superb functionality and convenience. The new AW-2 Chromatic Tuner enhances this basic concept by adding the flexibility of an adjustable angle for the display section, enhanced visibility from the built-in backlight, and improved fit to your instrument, allowing the performer to tune in a natural position. The new AW-2G adds a clip that's optimized for a guitar. With the AW-2/AW-2G, you'll be ready for stress-free tuning in any situations. Double ball joint allows multi-angle adjustment for greatly enhanced flexibility The tuner display section and the clip section are connected by a double ball joint that provides a broader range of left/right/up/down movement, dramatically increasing the range of adjustment. Even in cases where it was difficult to view the AW1, the AW2 makes it easy to adjust the display section for easy viewing, allowing you to tune in a natural position. Backlight ensures excellent visibility even on a dark stage The amount of light available to a performer varies greatly. Dim locations such as a stage or orchestra pit, glaring outdoor sunlight, evening dusk, or night-time illumination are often far from ideal. The AW2's backlit meter provides three illumination modes: Off for brightly-lit locations, Soft mode for somewhat dim locations where you want to conserve battery power, and Auto for bright illumination in locations of poor visibility. This ensures that you'll be able to tune perfectly under any conditions. In addition, Auto mode automatically switches to the lower brightness of the Soft mode when there has been no sound input or button operation for approximately ten seconds, preventing unnecessary battery consumption. Attention has been paid to numerous details to ensure ideal tuning, such as a large display font and a meter that clearly indicates the pitch discrepancy. Korg's proprietary clip design boasts a stable fit The AW2's clip section is a proprietary Korg design in which the opening angle and jaw angle of the clip has been carefully calculated to securely fit a variety of instruments. It boasts a greatly-improved fit with your instrument, allowing natural tuning that will not interfere with your performance. AW2 includes two clips for use with a variety of wind or string instruments 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. AW2G includes a dedicated guitar clip The AW2G comes with a dedicated guitar clip, designed for instruments that have a flat surface such as the headstock of a guitar. The inside of one side of the clip has a pad whose angle is adjustable, ensuring a stable fit even on guitars with headstocks of varying thicknesses. The display section can be attached to either side of the clip as desired; if you attach the tuner so that the display section is behind your guitar's headstock, it won't be visible from the audience, and you'll be able to tune unobtrusively with a clean-looking stage setup. Excellent tuning functionality: a broad tuning range and high precision 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, 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 tuner is powered by a widely available CR2032 type lithium battery, and with the backlight off, the battery life is an amazing 150 hours. Numerous other functions are provided, including adjustable calibration to support various concert pitches, auto power off, and memory backup. Markings indicate pure major third and minor third intervals for beautiful ensemble playing 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 choice of note to adjust when tuning to a pure major or minor third will depend on the music you're performing.
