The Maestro Octave box is a great choice among octaves pedals. One thing about the effect is a clean octave for versatility. You can add your favorite fuzz/overdrive for a raunchier sound. 

Condition: Very Good..There are dings and nicks however it's an original 1971 pedal so this is typical for its age. It can be finicky. These pedal seem to track better with the neck pickup. It also doesn't track chords well so this box is great at single note play. We recently serviced it so it's ready for whatever you throw at it. While it's less stable and accurate than modern octavers, this sound evokes the authentic atmosphere of the 1970s. 

Tested and fully functional.
A great early example from the first year of production.
