Okay, so I cheated with step 1 which is "build the whole box." When you build a box, it might not be anything like mine, so specifics are really irrelevant. The hardest part was getting the holes for the potentiometers to fit the existing board snugly. I could get new pots for the controls, but I thought this would be challenging enough. They already work, I just hated how they were positioned on the original pedal.
Here it is split apart awaiting some guts. I intend to remove the 9v battery clip since I plan to run this off of an adapter. I also haven't decided how I'm actually going to hold the two halves together. I could use screws, but since I don't need battery access and I don't think I'll ever want to get inside once I'm done, I might just solvent cement it closed and call it a day. I'm trying to think of something cool to use for knobs...
Here it is closed up. Nothing is mounted on the inside, but you see the amount of space there is to work with. I need to drill holes for the input and output jacks, the DC power supply jack and the momentary switch to operate the pedal. The scary part is phase 3. That's when the soldering iron comes out and stuff starts catching on fire. I ordered a bunch of parts and a solder sucker, so I've now invested more than the cost of the pedal in this project. But hey, its educational.
