I'm not sure I'll modify my 300s, but I know what you mean about having a
very narrow range over the fine tune control. I also have about a 3 semitone
range on my diy CEM 3340 VCOs which I didn't like at first, but make it so
easy to get into either zero beat or a "perfectly detuned" mode. Most
commercial synths (like my 2600) have about an octave over the fine tune
control which makes this kind of "fine tuning" very difficult.

I just looked at the MOTM 300 schematic and was wondering if you (Larry)
tried merely changing out R3 (a 3.32M resistor) to something like a 10M which
would eliminate cutting the PCB trace?
