On another schematic I found it had the positive side connected to the B pin of the transistor. I made that change on mine and get the exact sound from "What is life" by george harrison on the beginning lead line (which is rumored to be a pep box.)Eparkerhttps://www.blogger.com/profile/11213327083957895620noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-53000551143273409212020-05-15T21:13:16.286-04:002020-05-15T21:13:16.286-04:00Do you happen to have the schematic for the Silico...Do you happen to have the schematic for the Silicon Version?

I seem to be getting true bypass, but when I switch the 3pdt switch to run through the effect circuit it just sounds like the bypass with a loud hum over the top. I've tried it again with fresh components, but still no joy.Anonymoushttps://www.blogger.com/profile/06823674926108750156noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-17523313073797041292016-03-28T10:26:22.010-04:002016-03-28T10:26:22.010-04:00Awesome!

Just remember those are PNP transistors, so make sure to use a positive ground power supply, and orient any polarized components like the ones on the perf side of the drawing.
