PedaleGuitareComp

Guitar Pedal — Analog Compressor

Complete analog guitar compressor pedal project, including schematic and PCB design (KiCad) and simulations (LTSpice).

Quick overview

This project designs and documents an analog guitar compressor: input/output adaptation, amplification, envelope detection, and gain control. It includes the schematic, PCB, as well as simulations and test results.

Key features

• Analog compression: dynamic reduction of the audio signal
• Complete signal chain: input adaptation, amplification, peak detection, gain control, output adaptation
• Hardware design: schematic + PCB routing in KiCad
• Simulation: LTSpice models and sub‑block tests
• Visual documentation: block diagrams and simulation captures
