A chromatic tuner will tune to any note including sharps and flats. Its tuning range on most models is almost as wide as all the notes on the piano. Therefore, a chromatic tuner
can be used to tune any instrument. A guitar or bass tuner can
recognize only the notes of the strings on the instrument (Guitar:E-A-D-G-B-E,
Bass:E-A-D-G). And a violin, viola or cello tuner can recognize only the notes of the 4 strings on the instrument
(Violin:E-A-D-G, Viola/Cello:A-D-G-C).
