the lo-fi pedal on geofex

[hobageeba]

hello.  i'm really new to this whole stompbox building thing but i found a schematic on geofex.com for a lo-fi/telephone/noise pedal.  it seems like a really cool idea but i was wondering if any of you have successfully built this pedal.  i also don't totally understand the schematics.  it seems like the bypass switch isn't wired to the input or output jacks.....is that wierd??  is that even a bypass switch??(it's in the noise source section).  and, it seems like there's only one pot ( in the panner section).  if any of you can help me out that'd be awesome.  thanks!!
