Project Busker

I promised I would build my daughter a busking amp for her Birthday. That was 18 months ago 😫 This project is based on the excellent hackaday article from David Silverman (details below). The final plan is for a self-contained busking amp with the following features:

  • 2 XLR microphone inputs, each with it's own pre-amp and reverb module.
  • An electric guitar amp with effects, built using a raspberry pi 4 with an AudioInjector hat
  • A hardware mixer
  • a power amp
