If the author is reading--definitely use wood glue for the next one, not just nails. I know waiting for glue to dry sucks (that's why I do metalworking as a hobby) but it adds incredible amounts of strength. For something like a pedal board, glue is a necessity. Stomping on it will gradually loosen the nails. Plus, glue holds across the whole joint, not just at the 3-6 locations that have nails. For a proper glued joint, the wood itself will fail before the glue will
Not a bad looking project for a first-timer with limited tools though, the end result looks great. Fine woodworking is hard, but the end result is worth it, just like anything else that is difficult. And I can definitely agree that having some other hobby besides CS/IT is a good thing to keep sane.
Edit: to provide some background , the reason I know a fair bit about wood construction is from building experimental aircraft with wood wings. Still hated the woodworking aspect, but the plane flies and I'm confident it's solid.
