Yeah, this is a cool idea. Offload some of the manual labor to the consumer letting them learn about electronics in the process while even allowing them to customize their pedals to their liking.
Maybe a compromise between building the pedal completely and buying a pre-made one: modular pedals. You get the chassis, which can hold several ‘modules’, which you receive mostly complete, but still requiring a bit of assembly. That way, you can build a custom pedal with a minimum of confusion, but still making it extremely easy to mod.
