I can finally say this one is pretty much finished. I ordered some transistors from LIC Pedals and received them yesterday. The guy also sent me a proper layout and I completely rebuilt my clone using axial lead electrolytic caps and some of those old carbon composition resistors (I tested them first with both of my multimeters) . It sounds great and cleans up nicely with my old Kay Effector guitar, but not with my Epiphone LP. I guess it's the different pickups. The effect even has less noise than before.
