Open-Guitar-Pedal

The pedalSHIELD Arduino guitar pedal by Electrosmash:

The shield has three parts:

  • The Input Stage or Preamp: Amplifies the guitar input signal and sends it to the Arduino microcontroller to be processed.
  • Arduino Board: It does all the Digital Signal Processing (DSP) modifying the signal and adding the effect (delay, echo, distortion, volume…).
  • The Output Stage: Once the waveform is processed, the signal is taken from the Arduino DACs and prepared to be sent to the Guitar Amplifier. This part also includes a Summing Amplifier which is very useful for delay effects like echo or chorus.

    Awesome design I like pcbs which also function as enclosure

      A stomp switch on the PCB itself is a really bad idea though. You’ll very quickly crack the solder joints.

      Neat project though.
