The instruments can be voices of 438 Hz to 445 Hz on. Important for flute for piano (440 Hz), and flutes in the group (442 Hz). But who spends that kind of money for a tuner who knows? :-)
I need not mention that "Brass and Wind" all brass and woodwind includes. But - out of sheer desperation, because I've just found a good guitar tuner - I use this here now and my guitars. And what should I say? Very quickly, accurately and completely accurate!
