Guitar Effects Pedal

Electric Guitar Player | Microcontroller Programming Service

The aim of the project was to create a stompbox-style analog guitar effect processor for mass manufacturing. These devices are designed to enhance the tonal quality and versatility of the guitar, providing musicians with a wide array of sonic possibilities. By combining traditional analog circuitry with modern design techniques, this processor promises to deliver an unparalleled auditory experience.

Circuit Design and Construction:

  • Custom-Designed PCB:
  • The Printed Circuit Board (PCB) is meticulously designed to host the analog circuits, minimizing noise and maximizing signal integrity.

  • Impedance-Matched Audio Paths:
  • Carefully designed to preserve the tonal quality of the guitar, ensuring that the true character of the instrument shines through.

  • Power Supply Filtering:
  • Dedicated circuits filter out any noise from the power supply, ensuring that the audio signal remains clean and uncolored.

Control Systems and User Interface:

  • Analog Control Interface:
  • Features an intuitive layout with stomp switches and knobs, allowing for easy manipulation of the effects in real-time.

  • Preset Management System:
  • Enables users to change between tones using the selector switch.

Innovations and Enhancements:

  • True Bypass Wiring:
  • Ensures that the guitar's signal remains unaffected when the processor is disengaged, maintaining signal purity.

  • Signal Clipping and Distortion Control:
  • Carefully engineered clipping stages provide a range of overdriven tones, from subtle warmth to aggressive distortion.
