Another way to match JFETs?

[Perrow]

Suddenly, sitting at my workbench (and charging alkalines), I had an idea. What if slight mismatch of transistors in this application is actually desirable.

Train of thought:

-With perfect matching the transistors work "in unison".
-When the LFO "passes" the phase sweeps "hard and fast".
-If the LFO at some point misses the resistive range nothing happens to any of the transistors.
-With a slight mismatch the collective resistive range if wider.
-With slight mismatch not all stages stop sweeping at the same time.

I like your thinking, there... If they were all perfectly matched and started and stopped at exactly the same time, you'd get a triangle response in the phasing. If they start and stop sweeping at slightly different times, you get a smoother response curve, which would be more pleasing to the ear, I guess.
