"bleed" usually can be mechanically adjusted: just loosen the 
potentiometer a bit and turn it so its really closed when the pedal 
is all down. Sometimes there is an even easier way to adjust just the 
tooth wheel or so.

another problem is that some pedals dont use the whole rotation angle 
of the potentiometer, so it never goes to full volume.
The Bespeco is not just the cheapest but also mechanically well made, 
at least in this respect.

I found that one of the critical points for the pot is the pressure 
on the axis. This depends on the construction and on the pot itself.
I made exellent experiences with the Bourns 90 series. They have very 
little mechanical resistence, so the whole system works with less 
force. I pedal a lot and they work for at least 5 years.
