you mean it has a lot of friction? may be an advantage for standing
use, but... no, I dont want to make any efforts ;-)

is it the potentiometer that causes the friction or is it the turning
mechanics?

yes, but a control voltage also works.

sounds funy, but why not? Lets call it monkey pedal and start to
train the toes...
I learnd from my good old HAMMOND M3 to control a switch (which I
redefined as Leslie speed) in the horizontal plain on the volume
pedal.
Then I imitated the same lever on my Schaller pedal for Overdub, but
ended up simplifying it, without lever, just a keyboard type of
switch that is operated toards the left with my right bit toe. Worked
easily from the start.

I built one with a piezo in it. But I dont like to have to press all
the time, I want to be able to leave it in some position...
As I saw, Chapman made effect pedals on such pressure control principle,
right?
