I am the second owner and purchased this pedal from a person back in the mid 70's. If you are reading this you probably know the history and pedal versions more than I do. I read it is rumored to have connections with Jimmy Page of Led Zeppelin and Steve Hackett of Genesis. 

Physical condition is good. It has the expected scratches, chips, and oxidation on the case. I plugged in a bass guitar and it works fine but the pots are scratchy. 

The original owner switched out the knobs (I assume visually better from a distance) and installed an on/off switch (my guess because to shut off the unit's battery you need to unplug a cable). He also wrote stuff on the inside which is funny and put a stamped date of 1975. If you are not a purist.....this is the pedal for you!

My price is below average of what I've seen them sell for....which is amazing.
Comes from a smoke free home.
