Colorsound Supa Sustainer capabilities

[martbob789]

For anyone who knows, has or has built this pedal please help me...  I'm wondering what the range is for the sustain.  If I hit a note (preferably one on the B or e strings), how long will that note last compared to it with out the sustain pedal?  Also, what exactly does the sensitivity knob do?  Does it have to do with the attack or how much sustain I want?  Lastly does this pedal work like the EHX Soul Preacher (except without the switch for attack)?  I've played this pedal and it sustained a note at the same volume for about 6 to 8 seconds.  Would this pedal do that or is it better or worse?
