An instrument tuner that works by sensing the vibration of the instrument it is therefore not affected by background noise. I has a visual metronome as well as the ability to tune up to four flats while displaying standard tuning. It can also display standard tuning while using a capo up to four frets. The only tuner with both these features. Even tunes a 12 string guitar. Chromatic mode makes it possible to tune virtually any instrument.
