I still disagree. Having a honkin big knob doesn't guarantee that the 
pot itself is capable of doing the fine control necessary. Trying to 
move the pot wiper in smaller and smaller increments causes 
mechanical limits to come into play, including backlash, friction on 
the wiper, and shaft wobble. You could find yourself unable to zero 
in on the 'sweet spot'.

Now if you put a multiturn vernier under the knob, I'd agree with 
you. But it would slow you way down doing large manual sweeps. That's 
why coarse and fine are a good idea on both a VCO and a freq shifter.
