There are a number of such devices available.  I own one made by BORG
which has an acoustic mike.  You play the instrument and one of a row
of LEDs across the top lights indicating the note and if it is # a
second LED lights indicating that.  Next to the LEDs is a meter which
indicates with two arrow LEDs wether the not is sharp or flat from
the indicated note and both light if the note is within acceptable
limits.  Also in the meter is a needle which indicates the cents
deviation from flat.  The fundamental frequency 440 can be adjusted
to about seven different frequencies and it even has a special mode
for the guitar.  About twice the size of a candy bar unfortunately
it only covers a 4 octave range.  They have a model out now, however,
that covers the full 8 octaves and eliminates the guitar mode.  Mine
was around $50 the new one is around $70.  I have an ad at home for
a similar unit by another manufacturer at around $70 available mail
order which I can look up if you are interested.  You might want
to check your local instrument store.
