So I got a broken EHX y triggered filter and the info on it seems a bit scarce. This board looks a little different than any other pictures I could find. The board is detached from all the wiring so I have a bit of a project. It looks like it has been modified or repaired previously.
here are some gut shots if anyone is interested. I'm sure I can figure out what is going on but I figured I would post my pics as documentation since it is a pretty rare pedal.

Yep, just as ugly as mine.

The leads on that transistor desperately need to be insulated from contacting other thngs.  You can slip a bit of wire insulation over those leads.

Mine works if that can be of any use to you.

The posted scheatic desperately needs a redraw.  I find it very hard to interpret.

What I have left to figure out is how to wire up the jacks and stomp switch. The wire on the left side near the blue cap looks to be the out that goes to the switch...

I just designed a new fuzz circuit! It almost sounds a little different than the last fifty fuzz circuits I designed! ;)

The redrawn schematic is here:

Thanks. If you look at the pics in the first post, my board is a little different. For one, that pic doesn't have the transistor dangling on the solder side of the board. I believe there are a few other discrepancies but I haven't documented everything yet.
