Oh rock on! I am looking to build things for my daughter and her guitar. I am absolutely going to try and build this.
Is there a specific reason you went with the Pico over an ESP32? On the surface, the specs for this application seem about equal. WiFi and Bluetooth would be nice, but not needed. I dunno if the DAC on the ESP32 would be of any use here either.
My guess about your selection was either about simplicity or availability.
One of the reasons to go with the Pico is that Espressif seems to only support their chips for a limited time. I wanted to use something like is guaranteed to be in production longer. That said, the effects code is mostly portable, so it wouldn't be that hard to move to another microcontroller.
Thanks for the response! I may design a daughter board that I can use to swap between the two and not alter your design too much, if at all. (Why risk breaking something that ain't broke?) Your code and approach to this seems hyper-clean, so I don't want to lose that.
