Planet Waves PW-CT-02 Multi Function Chromatic Tuner
This is a very versatile multi function tuner. It comes with a standard quarter inch input and a built in piezo sensor that allows the tuner to pick up vibrations rather than sound waves. But it also comes with a standard and very sensitive condenser microphone for acoustic instruments. Hold it over the sound hole or clip it to the headstock or bridge, you'll be in tune all the time, with out fail.
