Any one have a schematic for the PEI Junior pedal?

I started to draw one out from my unit a while back but I don't think I finished it.  It uses the ICL8038 chip.

What does the sensitivity switch do? Is it quite noticeable or is it subtle?

This one uses the 350y IC with the same ic noted above.

The whole effect is pretty subtle.  Definitely not as pronounced as a Phase 90. 
The only difference I can hear in the sensitivity settings is the LOW setting has more noise.  I assume it's an impedance thing.

More noise with the low setting is the same for this unit. Effect is a nice wobbly chorus
