Planet Waves Universal Chromatic Tuner.

Planet Waves' Universal Chromatic Tuner includes a patent-pending fold-out stand with a bracket. You can hang the tuner from the soundhole of your acoustic guitar and enjoy handsfree tuning freedom. A 1/4" input plus a built-in mic allow you to tune anything from a 5-string bass to a mandolin. It also does an excellent job of tuning band and orchestra wind, brass, and stringed instruments.

In auto mode, you play the note to be tuned and the tuner will automatically recognize the pitch and the LED lights and LCD meter will indicate whether the note is sharp or flat. In manual mode, the user selects the note to be tuned. The 2 displays offer visibility regardless of the lighting you're playing in.
