Hate wasting batteries in your guitar/bass/instrument tuner? Then Fender has something for you: the GreenTuner! The GreenTuner 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 your instrument perfectly in tune, and without wasting (or having to pay for) a single battery.
