The Korg Miku Stomp Effect is an effects unit for guitar that allows you to have virtual idol Hatsune Miku accompany you while you play. All you need to do is connect your guitar to the unit and Hatsune Miku will sing along with whatever cords you play. The vocal system is courtesy of Yamaha's unique eVocaloid and as you'd expect, Hatsune Miku herself is decorating the effects unit's stylish exterior.
There are several settings, with 11 different lyric patterns, including one in which you can create your own and a random setting. You can even make Hatsune Miku vocalize your own choice of lyrics using the dedicated iPhone app.
