Tune Up

Korg bEver have to tune a music room’s worth of string instruments? Korg’s Headtune can make quick work of it. Just clip it to the guitar and watch the LEDs as you tighten or loosen the strings. The device’s piezoelectric sensor accurately records and displays the string’s note. It costs $20 and is easy enough for beginners to use to tune guitars, basses and ukuleles.
