Qwik tune qt11 electric guitar/bass auto tuner

Super accurate tuning plus an electronic pitch pipe with an internal speaker that plays E, A, D, G, B, and E tones for by-ear tuning. Off Meter Tuning: when you're way off pitch and don't know whether to go up or down, the QT-11 tells you which string you are attempting to tune so you can tell at a glance whether you need to raise or lower the pitch. Also features a high-sensitivity mic, a fast-reacting meter, and three LEDs. Batteries are included
