Korg GT120 Chromatic Guitar and Bass Tuner

The Korg GT120 is a guitar and bass tuner that combines the accuracy of needle-type meters with superior functionality and a new, easy-to-use design.
The needle-type meter that has enjoyed enduring popularity for its clear visibility and stable detection is now available in a handy size, with the meter located at the top of a sleek black aluminum body. The backlit LCD screen also shows the calibration setting, flat mode, note name, and the remaining battery life. Flat (b) and sharp (#) LEDs light to indicate pitch drift or perfect tuning in a way that's easily visible even on a dimly lit stage. A large dial makes it easy to choose the mode you need to use. Using the stand located on the back, you can conveniently place the GT-120 upright on your amp or other surface while practicing.
