Octave Fuzz Pedal – Guitar Effects Unit

Here the circuit diagram of octave fuzz guitar effect pedal. This guitar effect unit is great sounding octave fuzz, with an optional mode of just fuzz. The fuzz is really a absolutely rectified signal and is fairly chewy. For some the Fuzz alone could possibly not be loud enough, this could be fixed by raising… Read More »

5V Regulated Power Supply with OverVoltage Protection

This is the circuit diagram of 5V Regulated Power Supply circuit, featured with over voltage protection. The circuit is based regulator chip 7805; Thyristor SCR 2N1595 and Dioda Zener 1N3997 for overvoltage protection circuit. The 5V regulated power supply is apply 74LS series integrated circuits which has to be really precise and tolerant of voltage… Read More »

UniVibe Pedal

The Univibe is actually a footpedal-operated phaser or phase shifter for generating chorus and vibrato simulations for electric organ or guitar. It was introduced in the 1960s by Shin-ei, and was intended to emulate the “Doppler sound” of a Leslie speaker. Although not a really successful Leslie-simulator, the Univibe has turn out to be an… Read More »
