and furthermore, Stooge Larry's module, cool as it is (I have one),
won't help you if you bump a knob. You have to be in tune first,
then use the octave/step switches...
I seem to remember a mod discussed that narrowed the range of the
FINE control. Was it Stooge Moe that discussed this?
BTW, even if you are not a builder, it's probably an easy part(s?)
replacement.
