Fuzz Box (Distorion Pedal) Electric Guitar Effect

Audio and Amplifier | By: Diagram mania

The two transistors amplifies the input signal from electric guitar. The two  silicon diodes (any small signal type can be used)  clips the amplified signal to produce a  highly distorted output, after filtering the high frequency component using a 500 pF capacitor. The amount of the fuzz is adjustable from maximum fuzz to pure clean […]

Tremolo Effect

Audio and Amplifier | By: Diagram mania

Tremolo sound effect is basically an amplitude modulator.  Some people might get confused with vibrato effect, but vibrato effect is a frequency modulator, big difference. When you apply a tremolo effect on electric guitar for example, you’ll hear something similar with turning the guitar’s volume knob up and down, while vibrato effect will sound like […]

Fuzz Box Distortion Pedal – Guitar Effect

Audio and Amplifier | By: Diagram mania

This guitar effect circuit uses a simple high gain amplification, followed by a symmetric clipping using parallel diodes clipper. The gain of the 741 op-amp pre amplifier will be R3/(total impedance of guitar pickup + C1).  With 1 kOhm guitar pickup and C1 combination impedance, the gain would be more than 1000x, this would be […]

Blackbox Sustain, An Audio Effect for Electric Guitar

Audio and Amplifier | By: Diagram mania

Sustain effect in electric guitar is similar with compressor effect. The purpose of this effect is to make the note last longer when the string is plucked. The mechanism is actually work by controlling an amplifier gain, where the gain is automatically increased when the note fade out, therefore the note will be sustained to […]

Ibanez Fat Cat Distortion Pedal

Audio and Amplifier | By: Diagram mania

Ibanez Fat Cat distortion pedal (Ibanez FC-10 Fat Cat Distortion) is good for blues, rock, pop, alternative, but not for metal. You can hear the fat tone even at maximum overdrive. Here is the circuit schematic diagram. You can see the the first transistor 2SC1815/BC546 is configured as voltage follower, giving a high impedance for […]

Single Supply Octave Shifter: A Frequency Doubler Effect For Electric Guitar

Audio and Amplifier | By: Diagram mania

Octave shifting or frequency doubling effect for electric guitar is done by rectifying the original signal, just like AC to DC conversion inside your AC-DC power supply adapter. The circuit for this audio effect is not new, I’ve seen it on many publications. Here I present the circuit’s schematic diagram, but I’ve redesigned the circuit […]

Carlin Fuzz Compressor: Two Guitar Effects in One Box

Audio and Amplifier | By: Diagram mania

It’s easier to manage if we put the distortion and the compressor effect in one box. This Carlin fuzz compressor use unique method to give sustain and distortion effect in mixed circuit. Seem that the circuit do the dynamic compression and distortion in a single negative feedback loop. Here is the circuit schematic diagram: The […]

Dynamic Compressor, Self Powered Circuit Design

Audio and Amplifier | By: Diagram mania

This dynamic compressor will give about 20dB compression, at very wide input signal range 100 mV to 10 V.  Another advantage of this circuit is that this circuit doesn’t need any power supply, we call it self powered, or more accurately, signal-powered compressor. Here is the schematic diagram of the circuit: A part of the […]

Fuzz Distortion with Wave Shaper

Audio and Amplifier | By: Diagram mania

Based on the squaring property of two back-to-back diodes connected across output and inverting input of the op-amp, IC1B forms a rather straightforward fuzz circuit. The squared output signal coming from IC1B is converted into a triangle-shaped waveform by IC1C and related components. IC1D is wired as a virtual-earth mixer, summing the linear, squared and […]

Guitar Pre-Amplifier

Audio and Amplifier | By: Diagram mania

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 […]
