The ENO EMT-320 digital tuner has one of the most innovative design of all tuners. Simply clip the tuner on to the headstock of your guitar or other instrument and the built-in microphone clip will detect the vibrations caused by the strings.
The LCD display will indicate when each string is tune by the digital needle resting in the middle and the central LED will also illuminate.
Don't forget this is also a metronome which is excellent for helping you to play in time and also experiment with time signatures.
Lastly, there is also a tone generator which will sound a note if required-this helps in understanding notes and pitches when tuning.
