I intend to implement a guitar multi effects pedal using DSP. However, I have only seen single effect pedals built using Arduino Uno's and Raspberry Pi's. Are there any suitable boards to use for this project or are there limitations which mean only one effect can be used at a time?
 

That’s a pretty broad question. There are a lot of things that can limit whatever undefined thing you’re trying to do. Memory. Processing speed. Bit-width. Built-in resources (like multipliers). I don’t think Arduinos are really designed for ‘serious‘ audio processing, maybe look into FPGAs.

Define what you actually want to do, then figure out what resources you’ll need. For instance, a filter is going to require a lot of multiplications. Can your chosen board do that fast enough?
