Absolutely love the idea ^^ all the musicians I know and I have crossed , when I tell them about the hobby I get the same state of amazement O_O... They all just don't know about it. I tell then all you need is a soldering iron, a pcb with a good build doc ie: a madbeans project, and tayda as a good starting sourcing site for regular components and your good to go.
If it gets someone else into the hobby I am all for it!
