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 »
Designed by Don Tillman, this guitar pre-amp circuit design is dedicated for people who don”t like op-amps module. This circuit is a discrete JFET pre-amplifier design, use 2N5457 as the main component. It has low noise, low distortion, low feedback, overloads gracefully, is small, etc.
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 »
The following scheme diagram is the circuit diagram of VOX treble booster effect. A treble booster is an effects unit used by guitarists to boost volume and especially the high end of their tonal spectrum, and was popular mostly during the 1960s. VOX made a variety of boosters that were meant to be plugged directly… Read More »
The following circuit is tube distortion pedal for guitar effect. The circuit designed by Ron Black. Circuit Notes: IC1 : 747 dual op-amp, other ICs may be substitued but pinout will different. You should check the datasheet IC2 : LM340K-12V Voltage Regulator All resistors are 1/2 W Bridge Rectifier – Full wave bridge recitifier, 50… Read More »
The following diagram is the Theremin music instrument effect. A guitar or instrument amplifier is an ideal companion unit for the theremin; either one allows bass or treble boost, as desired, and fuzz (distortion) or reverberation (if these features are incorporated in the amplifier”s circuit). Simply provide a suitable cable plug and connect the theremin”s… Read More »
This is the circuit diagram of BOSS Slow Gear SG-1 effect for electric guitar. The Slow Gear SG-1 effect sounded like a guitar player riding the volume knob of the guitar. This produced a cool swelling sound with a gradual attack, almost like a violin. At $99.50 original retail price, the Slow Gear was a… Read More »
The following diagram is the schematic diagram of electric guitar effect: Electro-Harmonix (EH) Big Muff Pi. The EH Big Muff Pi effect circuit would probably be better making the change by a modern input-jack power and a DPDT bypass switch. The types of transistors and diodes are unknown. It is likely that any high gain… Read More »
