Honestly I'll take instruments constructed very cheaply out of modern materials too.
So I have this love for the Cigar Box Guitar, and it's been expanding in the last few years to include the home built anything.

You can see what the innards look like and everything. The idea in general though is that the Cigar Box Guitar was a depression era American instrument that was made by folks cuz we were too broke to make whole guitars. Consisting of a stick, a cigar box, and some strings. Folks have really put a science to it, but the idea of making them out of whatever remains and I think that's super cool.
Nobody ahould be surprised that I, the guy who tells everyone to just do whatever is now an amateur luthier.
