Description: This is an oscillator sync circuit that gives the kind of effect you find on old analogue synths. Oscillator synchronisation is performed by using one oscillator to reset another. In this instance the guitar signal is used to reset an oscillator running at a higher sweepable frequency. The effect is not dissimilar to flanging. Not one for the tone freaks, this is a destroy-your-tone effect for noise vandals. More: The front end is copied from the MXR blue box.
The oscillator sync circuit described functions by utilizing the principles of oscillator synchronization, where one oscillator influences the operation of another. In this design, the primary oscillator is driven by an incoming guitar signal, which acts as a control signal to reset the secondary oscillator. This secondary oscillator operates at a higher frequency, which can be adjusted (sweepable) to create various modulation effects.
The circuit architecture typically involves integrating an input stage that captures the guitar signal, which is then processed to produce a control voltage or pulse that resets the secondary oscillator. The reset action effectively synchronizes the oscillators, leading to unique sound effects reminiscent of classic analog synthesizers.
The front end of the circuit is derived from the MXR Blue Box design, known for its distinctively gritty and lo-fi sound characteristics. This design choice contributes to the overall tonal quality of the circuit, emphasizing its capability to produce a "destroy-your-tone" effect, which is particularly appealing to those seeking unconventional and experimental sound manipulation.
The resulting audio output is characterized by a rich texture and modulation depth, akin to flanging effects, yet distinctly unique in its approach to sound synthesis. The circuit is particularly suited for musicians and sound designers who favor aggressive sound manipulation and are less concerned with preserving the original tonal quality of their instruments.This is an oscillator sync circuit that gives the kind of effect you find on old analogue synths.
