Could you be a bit more specific?  Are you referring to the Sili-Face at runoffgroove.com?

Thanks Mr. B,
I did some more searching and found your Siliface ll Layout, It's at Runoff and Should I use a 2n3904 for Q1 and a 2n5088 for Q2 ? and on the input cap is it Electrolytic or Non Polirized

When they re-did Sili-Face 1's schem they just forgot to erase the + on the input cap. .01uF is never(that I know of) polarized.

2N3904 & 2N5088 should work fine also.

Thanks RDV,
I put it on the Breadboard and got Q1 - C= 1.171 B= .594 E= 0
                                                 Q2 - C= 4.62 B= 1.168 E= .658
I'll finish it tomorrow and try it out on my pedalboard, got to get ready to go tech for a Local Band that's opening for Al Green tonight, Can't wait, He's supposed to have Donald Duck Dunn And Steve Cropper with him tonight, Should be a Great show.

RDV, The Music was great, Ya just gotta Love that Al Green,
I had a ground wire in the wrong place on my StereoJack that gave me a great Honk when I tried the Face, Switched the wire and Wha-La, Very good sounding Fuzz Pedal, Simple, and cool the way the notes cleanup as they decay,I did get a slight change in the voltages after swapping the wire around, Q1 C=1.226 B= .663 E= 0, Q2 C= 4.52 B= 1.221 E= .622,
Thanks for the help and thanks Runoff for great soundin Pedal,
JD
