This is the circuit diagram of Fuzz Face mods, guitar effect pedal. This is a modified diagram and simpler than the original Fuzz Face diagram. You will find apparently two identical designs of the fuzz face. In one Q1 and Q2 had been PNP germanium AC128 or NKT275 types, in the other they had been… Read More »
Here the simple mic pre-amp circuit design based on single IC LM358. The circuit is very simple, inexpensive and easy to built. This mic pre-amplifier circuit operated with 9V DC voltage, you may use 9V battery for this circuit. Component Parts List: R1, R3, R4 = 10K R2 = 1K R5 = 100K-1M Potensiometer C1… Read More »
Here the circuit diagram of Maestro Boomerang pedal / Wah-Wah pedal for electric guitar effect. Note: Transistors Q1 and Q2 were designated P-2356. The Maestro Boomerang is not only a wide range wah wah pedal but also a volume pedal. It’s deemed as one of the best wah pedals ever built – and I totally… Read More »
Here the simple mixer circuit with 4 inputs and 2 operational amplifier (op-amp) modules: A basic mixer suitable for mixing microphones or even effects outputs. The overall gain from input to output is one if the pot related towards the input is full up. You can make this a net gain of ten (or any… Read More »
This is a A/B Box switch pedal schematic with two inputs and one output and featured with dual operational amplifier modules. This circuit was designed by Rick Barker. This A/B Box effect was originally designed for switching between different harmonica mics. This A/B Box featured low noise dual preamp for better performance.
The following circuit is an distortion booster effect for your electric guitar. I don’t know whether this circuit is really works or not, you may try this circuit with your own risk. The circuit is very simple with required only ten electronic components : two transistors, two diodes, five resistors and two capacitors. Supply voltage… Read More »
