Early 70's Cry Baby - Wah/Fuzz. You had to take to bottom off to adjust the settings on the fuzz, which you kicked in using the extra stomper at the front. But once you "found your sound", it wasn't too bad. Some classic fuzz tones in there.
Also have a Big Muff Pi from the same era. Second or third version iirc - known as the "Ramshead" version.
They both still sort of work, but are finicky. I keep 'em around mostly for fun.
