D'Addario PW-CT-02 Multi Tuner Tuner

The Planet Waves Multi-Function tuner can tune any way circumstances and your instrument dictate. This Planet Waves tuner boasts a 1/4" I/O, a sensitive condenser mic, plus a bracket/clip with piezo sensor that allows it to be hung from sound holes or clipped to bridges and headstocks. Choose from 2 modes and calibrate between A435 and A445. 

In Strobe mode, the played note appears in green on the tuner's rotary display while red LEDs chase clockwise if you're sharp and counter-clockwise if you're flat. They slow down and finally stop as you nail the pitch. In Sweep mode, the LEDS sweep left or right indicating whether you're flat or sharp. One-button operation makes toggling between modes easy and the large display is easily legible even when stage lights are dimmed.
