Another way to realyse this, is to build a unit which compares the guitar-
frequency with a divided Xtal-frequency. The difference-frequency shows
you the deviation of the guitarfrequency. As a display you can realyse a led-
bar. If the light of example 4 led moves left, the guitar-frequency is 
too low, if the the light moves right, the guitar-frequency is too high.
