This is the circuit diagram of Electro-Harmonix Soul Preacher pedal.
This Tube Sound Fuzz circuit is taken from the book of Electronic Projects for Musicians by Craig Andertons. This circuit applies a CD4049 Hex inverter, which consists of six inverting units, only two are being used in this circuit, so the others are disabled by connecting their inputs to the positive voltage source and leaving the output disconnected. This layout also uses various pins than the original schematic diagram for [...]
This is the DOD Overdrive 250 preamp circuit diagram. The DOD Overdrive 250 is Yet Another 741 With Two Diodes On The Output channel. It is almost exactly the same as the MXR Distortion Plus, and a number of other units.
Here the circuit diagram of octave fuzz guitar effect pedal. This guitar effect unit is great sounding octave fuzz, with an optional mode of just fuzz. The fuzz is really a absolutely rectified signal and is fairly chewy. For some the Fuzz alone could possibly not be loud enough, this could be fixed by raising the value of the 820 ohm resistor and lowering the 39k one. Or one could [...]
