Fender GT-1000 Green Kinetic Tuner

Hate wasting batteries in your guitar/bass/instrument tuner? Then Fender has something for you: the Green Tuner! You crank it up and it works! The Green Tuner features a built-in microphone and has a 1/4" input, and it will display the chromatic pitch as well as indicate if the pitch is sharp or flat. It even has a built-in flashlight!

But the unique feature of the GreenTuner is that the unit is hand cranked no battery required! Just crank the knob, and you're good to go, ready to get you instrument perfectly in tune, and without wasting (or having to pay for) a single battery.
