MOTM

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.
