Rechargeable Headstock Tuner from D'addario!
The D'addario Equinox tuner is an innovation in headstock tuners. For starters, the tuner is rechargeable, making the hassle of batteries a thing of the past. In addition, the tuner uses a piezo sensor. This means that vibrations are used instead of sound, so you can tune your guitar accurately even in the noisiest environments. The nice and bright display can be adjusted in an angle, so you can always see exactly whether you're in the right mood.
