From the project

Ignis overdrive guitar effect

This project presents the complete design and mathematical analysis of a versatile, fully analog overdrive guitar pedal built around an operational amplifier. At its core, the main amplification block delivers a massive voltage gain (up to 1000x), paired with a flexible multi segmented tonal shaping section.

The end result is a highly customizable overdrive capable of spanning from a transparent, mid-focused crunch to a thick, saturated lead tone, demonstrating a practical understanding of circuit design and mathematical theory usage.
