I have one of these just sitting around. Help me decide what I should build...I have no idea, really :-\
a few ideas:
If you like Big Muffs
A Fuzz Munchkin-alike: http://www.tymguitars.com.au/?page_id=620#fuzzmunch
Your favorite BMP, but the second footswitch toggles between the volume pot and a fixed resistor so that engaging it equals max volume
A delay which uses the "crazy oscillation" footswitch
A boost + OD, Dist, or Fuzz
Your favorite dirt pedal circuit, and then you use the second footswitch to toggle between two modded settings, switching between three components
You could also use a pot like this: http://www.smallbearelec.com/Detail.bok?no=1213 (http://www.smallbearelec.com/Detail.bok?no=1213)
Then you could have two different gain pots for an overdrive of some sort, and you could switch between the gain pots. The EGO is a good candidate for this, as is a green bean.

The dual gang pot idea is brilliant!
So...I also have an extra wah enclosure...what do you think? Volume pedal? wait for the univibe? hmm..
...I've been looking for a wah enclosure for the upcoming weener wah!!!
I finished my wolfshirt (fuzz/octave) last night and ive put a footswitch in for the octave.
