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 effect in its own right, putting its stamp on tracks like Robin Trower’s “Bridge of [...]
This is the circuit diagram of Univox Super-Fuzz Pedal. This pedal is actually a 69-to-early 70’s design that consists of two special capabilities. They are the octave generation effect from the differential-pair-with-collectors -tied-together along with the option of just a clipping amplifier or a 1kHz notch for different sounds. The odd-diffamp is basically a full wave rectifier as applied in this circuit. The clipping is all completed using the pair [...]
How this sound activated light works: The condenser microphone fitted inside a position to catch the sound and generates AC signals, which pass by means of DC blocking capacitor C1 for the base of transistor BC549 (T1). Transistor T1 as well as transistor T2 amplifies the sound signals and delivers current pulses within the collector of T2. When audio is generated in front from the condenser mic, Triac1 (BT136) fires, [...]
This is the circuit diagram of Vox Tone Bender Pedal. The circuit is very similar to Fuzz Face pedal. The Vox ToneBender will have a lot more treble response than the Fuzz Face…maybe to help brighten up those characteristically “dark” sounding British amps some. Using a Vox ToneBender with a Fender Twin, or any other Fender amp, would be nearly ear-piercing with all the treble that’d be blasting through. Another [...]
