Originally purchased in Seattle, Washington in 1966 then resold in 1972 to a gentleman who kept this baby stored in a cool dry place for a good 4 decades. The pedal functions but this piece of electrical equipment is half a century old. To bring it to a condition where it sounds as good as possible, it will require a little work removing some corrosion. I will also sell with this at least 6 preserved soviet era germanium transistors, that way if one of the transistors goes out you can replace it with a little handy work with a soldering iron. Much love friends, i hope this pedal finds someone who will love it like it deserves! Let it recapture the magic of 60s rock and roll for youCONTACT ME IF YOU WANT TO MAKE AN OFFER!
