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 »
This is Dan Armstrong Green Ringer guitar effect for your electric guitar. The guitar effect is sold at high price at the market. Now, you can build your own low cost guitar effect… 🙂 The transistor marked ” * ” has no markings other than three stripes: green, blue and white from top to bottom.… Read More »
Below is a mic compressor circuit that uses transistors as active components. VR1 and VR 2 is used to control the tone from the microphone, while VR3 and VR4 strengthening works to control the audio signal in the compressor mic. C10 must be used in this circuit. The circuit I got from my local computer… Read More »
Here’s a very simple circuit inverter that converts DC current into AC current, from 12V DC to 220V AC with output power of 5W max. Inverter circuit is typically used for emergency lighting, since the power output is small, which is about 5W only. But you can use this inverter for other purposes that do… Read More »
The following circuit is a 5W stereo audio amplifier, built based on single amplifier IC TA7227. The TA7227 can be used for dual mode (stereo amp) and single mode (bridge connection/mono amp). This IC type featured some circuit protection: thermal protection, over voltage protection, current limitter and BTL DC short connection. The tone control circuit… Read More »
