want to try and build a volume pedal but having a bit of trouble finding a schematic for one. anyone out there have a good one or know where i could find one? Thanks
I would avoid the passive route, I'd suggest a buffer at the input or output as a minimum.

Old wahs are nice to modify for volume pedals. You could throw a booster pedal in to use as a variable boost, or even just a volume depending on the boost pedal.
