This is an excellent tuner, I like the that it give you the frequency and the note. I would also request that the tuner tell you what octave number the note is in. This would help to know what octave I am tuning in and if I am off by an octave but have the correct note. This would be most helpful when tuning after a change of strings. A second change might be reference octave and notes for different instruments. For example I play mandolin, octave mandolin, and banjo. Thanks for a great tuner, I’m impressed, keep improving it!
