Actually, I think growing your own hops to make your own beer is exactly in line with the pedal making ethic (coming from a complete pedal noob in myself). A full mash is probably equivalent to etching your own boards. For some people, it's just more rewarding to research the process and create things on your own. I started with basic soldering to replace pickups and soon enough I was buying giant boards of alder, mahogany etc. to build my own guitars. I wish I knew more about pedal science, but I like the creation aspect, similar to making my own pastrami, ribs, beer, mole, gardening etc.
