Anyone have any explanation ? Also the output impedance is not what you would expect and its hard to take measurements at the base of Q1. You would think gain would not matter, more gain means more feedback which means less gain, however it seems device gain does make a difference. As simple as this circuit seems its surprisingly complex, due to the feedback. Aim for about 1/2 supply on Q2 collector and adjust the feedback resistor for best fuzz. ![]() ![]() I've built one with PN2222 which is probably the most ordinary transistor on earth. I take a different approach than most, instead of scouring the planet for obsolete transistors I believe that whatever is in that old radio over there will work. This is a great circuit and a good first project if anyone is looking for one due to the low parts count.
