Distorsore Analogico in Linea

Aggiungi alla tua chitarra o sintetizzatore una potente fonte di distorsione con questo versatile progetto. Dotato di amplificatori saturanti a stadi successivi e modulazione dinamica delle basse frequenze, il PCB funge anche da elegante pannello di controllo ricco di manopole e interruttori per infinite possibilità di modellazione del suono.

This versatile project provides flexible and dynamic signal distortion as a sound effect for synthesizers and guitars. A chain of saturating amplifiers with switchable summation allows for many kinds of overdrive curves. A low-frequency modulator creates dynamically changing distortion. With a fully optimized design, the PCB works as an operative panel with knobs and switches, having other components at the back.

The concept behind this project is to connect several identical amplifier stages in cascade. An increasing input signal will first saturate the last amp, then the amp before that, and so on. Now, if you take the output of each amplifier and send this to an adjustable output summing circuit, you can create all kinds of overload behavior. You can see/hear this in YouTube demo movies here.
