I agree on the soldering part, it is one of the most valuable skills I have picked up, I'm sure you've found value in it, too!

I don't think people should be intimidated by soldering. It can be daunting at first because electronics can be complicated.

Soldering doesn't require electronics expertise. It requires a steady hand, a solder kit that costs about 40-50 bucks -- wait what a Weller WLC100 is down to 33 USD? What the hell? That is a super nice kit. Uh, anyway, cheap cost of entry. I do suggest you get what's called a "helping hand", or a "third arm". This will hold wires and bits in place while you solder them together, very useful. Brass cleaner is a good idea too, and don't forget the solder. Don't get hung up on what type of solder you use. Don't get stained glass solder, and get solder that's thin enough or thick enough for your application.

If you're worried about screwing something up, they sell solder practice boards that are really cheap, too. Just punch "Soldering practice" into Amazon or Ebay. If you're new, avoid things with like 0805 SMDs. The 0805 refers to the size of the thing you're soldering to a PCB, and the SMD means "Surface Mount Device". 0805 is pretty small, but it is nothing compared to soldering an 0402, which is much smaller!

This piano kit looks pretty lit, I might buy one myself just for funsies.

See how everything's labeled? It's Lego with an extra step. You're just following directions, putting stuff together, then soldering it in place. If you're fixing a controller pot, or a capacitor, or whatever, there are likely tutorials on the internet to guide you through it, step by step. It's Lego but instead of being held together with friction, it's held together with hot metal glue. Dear reader, you can do it.
