Funk (Twang) Guitar Effect Box

This is an audio effect circuit that give extra oscillation to your guitar, percussive, or semi percussive instruments, you can call it a funk box. This  guitar effect circuit is basically a damped oscillator that is set slightly below its critical oscillation point.  The oscillator part is constructed by feeding back the output signal through …

Mic/Guitar Compressor with Transitor Bias Control

This is a compressor circuit that can be used for dynamic mic, condenser mic, or electric guitar pickup. This circuit doesn’t produce very good sound output, but it has very stable amplitude/volume. This compressor circuit design is unique since it uses base current control for manipulating the gain. Here is the schematic diagram of the …

Analog Tremolo (Guitar) Sound Effect

Tremolo effect produce an amplitude modulated signal. Unlike vibrato effect that produce frequency modulated, this tremolo effect will produce the same effect as quickly turning up-ad-down your volume control repeatedly. Here is the schematic diagram of the circuit: Q1 is general small signal audio transistor, you can use almost any type of NPN small signal …

Big Muff Distortion Pedal Tone Control

Below is a classic tone stack from the Big Muff distortion pedal. Basically, it’s a pair of filters whose output is combined through the 100k mix pot. The 39k/.01 filter attenuates the highs and only passes low frequency. But, the 3900pF/22k filter does the opposite. This filter passes the high frequency and filters out the …

Passive Treble Control for Guitar Pedal

The R1/C1 network makes a low pass filter when the wiper is at the grounded end of the tone pot, and there is a treble cut. The C1 cap bypasses R2 when the wiper is adjusted so that it is at the top end of the pot and it creates a treble boost. The 100k …

Guitar Pre-Amplifier

This is simple circuit for Guitar Pre-Amplifier. This circuit has some advantages such as it will work under tough conditions, very simple and has high input impedance. This circuit will not load down electric guitars because of the high input impedance. This circuit can be used to amplify microphones. Here is the circuit:A 9-volt battery …
