- 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.
