This is in very good to excellent condition when you take in the age. I'm not sure when this was made so I'm saying between the 60s - 70s. Let me know if there is some way to know for sure

Fender Fuzz Wah. Unique device with selectable wah, fuzz, or BOTH!! Thick, pillowy fuzz and funky wah! This pedal is in original, unaltered condition. 9V operation only.
