I think getting my hands dirty with some pedal builds is inevitible...just the convenience factor alone would be worth it, once I knew my shit.
It was a matter of necessity for me. I get what I want. And I want cool pedals. But I also want my wife not to kick my ass. And so I taught myself how to build pedals. I have no actual skills when it comes to understanding audio circuits, but I can take a layout and make it into a pedal.
All you need to do is learn about resistors, capacitors, transistors, and diodes. Those are the main components. Resistors are easy - they don't have polarity. And film capacitors don't have polarity either - only electrolytic capacitors do. Components without polarity can be installed either way, there is no backwards. Diodes, electrolytic caps, and transistors need to be oriented properly or they will fail/fry when you introduce a power cource - or at the very least, it won't work.
You also need to learn about wiring switches, jacks, and potentiometers (which is just a fancy name for a variable resistor). Oh and some basic soldering skills.
Then you just need to search the web for schematics/layouts for pedals you want to build and then get creative with your enclosure and where you want the knobs/jacks/switch to be, etc.
