Sabine NexTune 6Z

NexTune tuners include a built-in tone generator for tuning or ear training, and an instrument input as well as a built-in microphone for acoustic tuning.Two simultaneous tuning displays are available: the extra-big LCD with its simulated needle display, or a three-color LED display. Both tuning indicators clearly show how sharp or flat you are, and both give you instant indication when you are in-tune.

The NexTune 6z has both Guitar and Bass modes, and the bass mode allows for tuning 5-string basses. Batteries included.
