The AW-1 packs a detection range of A0~C8 and superb functionality into an ultracompact and lightweight unit. 2 included clips (large and small) let you attach it directly to your instrument, for example to the headstock of a guitar or the bridge of a violin. Since the clip contains an internal piezo pickup that detects the vibration of your instrument, you can enjoy stable tuning even if you're in a noisy environment. The clips adapt to a variety of situations and instruments and eliminate the need for a contact mic or other pickup. Alternatively, you can clip the AW-1 to your music stand and tune using the internal mic.
