The circuit below is a Dynamic Mic Compressor circuit which is simple, easy to built, inexpensive but the results are quite satisfactory. Audio output sounded outstanding. The principle of this circuit is very simple, the first transistor is used as microphone pre-amplifier. Then a second transistor used as a buffer. And the third transistor is… Read More »
Here the schematic diagram of Axe Grinder Electric Guitar Effect pedal. You may download the PDF version at the end of the post. The Axe Grinder is designed with a few key fetures in mind, it not only serves a wide range of distortion sounds clipping part of the effect, it also gives the user… Read More »
The following scheme diagram is the four 4 band equalizer circuit. Equalizer device is generally used to improve the fidelity of sound, to emphasize certain instruments, to remove undesired noises, or to create completely new and different timbres. This circuit operated with 12VDC symmetrical / dual polarity power supply. Power supply circuit provided on above… Read More »
This is a very basic circuit diagram of 3 band tone control. This basic tone control circuit was originally intended for home audio use, but should be able to be hacked into an effect circuit with very minor modification. Resistance value of resistor R1 is left up to the user depending on gain needs, R2… Read More »
This is the one of many guitar effect circuits exist in the world. I have not made this circuit and I also do not know what kind of sound effect harmonic sweeteners, but hopefully this harmonic sweetener guitar effect circuit can help you get a nice effect for your electric guitar. A pair of red… Read More »
The following is a circuit of a simple AM transmitter. This circuit is available in kit form and can work well since the kit available on market. This circuit uses a combination of transistors SA101 and SA103, as the modulation signal amplifier.
Here the circuit diagram of Angry Beard III Effect for Electric Guitar. Build your own guitar effect because the guitar effect kits on the market are very expensive. The OP-AMP can be any single low noise op-amp, the original NE5534 used. The 2N44 is likely to be replaced by PNP germanium transistors other without much… Read More »
This is the scheme diagram of passive surround circuit. Passive surround doesn’t need any active components and power supply to make the circuit works. The circuit just need the combination of resistors and electrolytic capacitors. Circuit Notes: This passive surround circuit MUST be connected after power amplifier module. Use full range type of loudspeaker. Do… Read More »
The following is a circuit of a power amplifier 140W. This Circuit using 741 IC-based circuit opAmp as strengthening early before the final strengthening by four transistors thereafter. Make sure you use a heatsink on the transistors to reduce excess heat in the transistors. Power supply used is the type of dual polarity power supply… Read More »
