The AW-2 includes two clips (large and small) with a propriety design to accommodate a variety of concert band and orchestral instruments with different tuning "sweet spot" locations. The AW-2G comes with an adjustable-angle clip pad that is optimized for attaching securely to all guitar headstocks or other flat instrument surfaces. The AW-2G's display can be moved to either side of the clip, and when positioned behind the headstock, will not be visible to an audience.

Both tuners' double ball-joint allows multi-angle positioning with far greater mobility for the display section, allowing stress-free tuning even in the most unique positions. An internal backlight ensures excellent visibility, even on a dimly lit stage, and the backlight can be switched between Soft mode for low illumination and the high-brightness Auto mode, or turned off for well-lit situations. The energy-saving Auto mode automatically switches to the low-power Soft mode when no sound is present.

The AW-2 and AW-2G each have a tuning range of A0 to C8 and a full complement of solid tuning functionality. Special markings indicate pure major third and minor third intervals for authentic consonance. The Calibration function accommodates a variety of concert pitches. Users can select either the internal mic or the vibration-sensing Piezo sensor for optimum response, which ensures stable tuning even in a noisy environment. A Meter Reverse function allows tuning from any viewing angle. The tuners are powered by a widely available CR2032-type lithium battery, and with the backlight off, the battery life is an amazing 150 hours. Auto Power Off maximizes the battery life and a Memory Backup function is also included.
