Hey, I just completed my 2nd twin face fuzz. First one came out perfect. 2nd one works when the toggle switch is up (i believe that's the silicon) but the down is just silence. and it works in bypass. I touched up all the solder points on my transistors, and in the switch. Not sure if there's something dumb I'm missing or if it sounds like one of the transistors may be a dud. Any help would be apprecuated. thanks!
