EHX microsynth - building the squarewave section as a standalone fuzz???

[the3secondrule]

Hey guys,

I remember my old EHX microsynth being one of those pedals that was super awesome fun, but not hugely practical - except for the squarewave - man, I must have used that for everything in one of my old bands.

So I was thinking I'd try and whip up a schematic for the squarewave only - or maybe clean/squarewave/octave up.

couple of questions for starters (and yes I'm aware i'm probably biting off more than I can chew) 

I've entered the power supply section into eagle.
But it seems overly complicated


Could I just omit all of this and use a charge pump for -9v???

Next question ...

I'm working from the schematic here: http://www.harpamps.com/schematics/bsynth1.pdf
is everything here necessary for the squarewave to function?

Somehow that harpamps pdf doesn`t work for me.

Me either.
Link is not right....
