I usta have one of these, there was a
black cardboard shroud, kinda wedge-shaped,
taped over the photocells. The flap that
moves when you move the pedal lays flat
against the open side of the wedge when
it is in the 'closed' position.
I traced out the circuit at one time, doubt
I still have it, but as i recall the volume
pedal circuit was very simple, a resistor
which gets loaded to ground by the photocell.
So there is always some attenuation, and any light
leaking in will make it worse.
I had some noise problems which were improved
by changing the grounding a little (I think one
of the jacks relied on contact to the chassis
for its ground) and adding another filter cap to
the power supply.
I also added a level control to the wha circuit,
because it boosts the signal a lot, which isn't
