Master Crow,

Thank you for responding and please forgive my ignorance. I can do this if
it's just a matter of checking the voltage across the pot leads with a
multimeter. Otherwise I'd need specific info. If it requires special test
equip. I'd probably have to have an expert (such as yourself!) look at it.
Whatever it takes. FYI the trouble spot seems to be arounnd #2, or 9:00
o'clock. If I set it and leave it alone, it seems fine and cuts the freq. off
where it should. I've programmed and stored many different sounding patches,
that's why it seems to me that the filters are working properly. Anyway, just
speculation. Again thanks for the help.
