The pic on the layout shows the black battery lead going to the 9+ on the board..Is this right? Im wiring this w a 3pdt and it seems to me that the red lead goes there cause the black one is supposed to go to the ground on the input jack? Does this matter? Is it right? Or is one of those pnp positive grounding? It seems theres something missing here. I used the wiring diagram from http://www.generalguitargadgets.com/v2/diagrams/switch_lo_3pdt_ig_dcjack.gif. The only thing i did different from this is that the easy face schem  shows the positive battery lead going to the inpt jack so i did that and wired the black battery lead to power jack--basically i just reversed the battery leads. Is there anything else i need to do? I plugged it into the wall and nothing--tried a battery and nothing.. damn!  

Im thinking about changing this project to a pnp negative ground using this http://www.generalguitargadgets.com/v2/diagrams/fuzzface_lo_pn3.gif

Hi -Yes, the easyface is pnp, positive ground. Sound like you might be applying the wiring diagram from the LED wiring of a neg ground pedal. Wire the pedal like the easyface schem ( black to + on board), just reverse the colors for the LEDS portion, everything should be fine.

There was a version of easyface that was PNP but wired regular polarity( Fransisco P) , but none of the ones with my name on the bottom are like that.

I thought I read somewhere where you need a different kind og power supply with these positive ground versions? Any truth to this? Cause no matter what i do I cant seem to get any sound from this effect. I got my Q2 from steve at Small Bear. Its a big metal looking transistor. Im not sure  which lead goes to what since it was packaged with only "Easy" on it. I have a 2n3906 for  q1 but found the pinout online for that.

Any help?
