  • Make an Easy Guitar Distortion Pedal (STEP BY STEP!)

    You could use an MPSA13 for your transistor (Its a NPN Darlington pair Transistor, essentially it is 2 of the same type of transistors, the 2nd is amplifying the 1st) which will give more amplification.https://en.wikipedia.org/wiki/Darlington_transisto...or modify the circuit to accomadate this Sziklai pair (the Sziklai pair has one NPN and one PNP transistor)https://en.wikipedia.org/wiki/Sziklai_pair

    I think you will find that first 10k resistor that goes from 9v+ to your inpunt (Before the 1uf cap) is useless as the cap will stop the dc voltage from passing through to the transistor.I'm not 100% certain of this though

    Most likely the reason you are receiving radio signal is because you haven't shielded the project.All commercial guitar effects pedals are enclosed in a metal box shielding it on all sides and connected to ground (negative part of the circuit).without this the wiring will receive radio signal and the um of Flourescent lights and other power supplies that are nearby.If you dont have a metal box/enclosure then you can shield the inside of your box with aluminium/kitchen foil.Make sure you keep your circuit isolated from touching/shorting out positive parts of your circuit to the shielding. (Smoke comes out in some cases due to shorting your positive voltage directly to the shielding, blown caps and resistors and transistors)This will, as the word states, Shield your circuit and wiring fro...
