Instead of relying on soundwaves, which can be problematic if you’re trying to tune a guitar backstage at a noisy venue, the Headstock Tuner from D’addario detects vibrations to determine if a particular string is in tune or not. You simply attach it to any part of the instrument that vibrates when a string is plucked, and the device’s “optimally positioned, highly sensitive piezo transducer” will let you know if you’re ready to rock.
Now tuners that use vibrations aren’t new or anything, but the Headstock Tuner does seem particularly easy to use thanks in part to a backlit LCD display that glows red when a string is out of tune and glows green when it’s hitting the right note. $42 available from Planet Waves.
