Simply give the crank a few turns and you’re ready to tune. No more expensive and wasteful batteries. Includes built-in microphone for tuning acoustic instruments and 1/4" jack for tuning electric instruments. The built-in flashlight lets you tune on a dark stage.
Recommended instructions for usage: The first time you use the Chromatic Green Tuner it’s a good idea to “prime” the power cells by turning the crank 20 times. Any time you use it after that, 5 to 10 turns will do the trick. No need to charge it unless the lights on the tuner are dim. To conserve cell power, turn the power off when not in use.
No need for batteries - just crank up the power!
