This is a cool vintage Maestro OB-1 that I’ve had in my collection for years now. Serial number: 6621. It’s not in perfect shape, as it’s very old and very used (purchased from an old studio that was closing). Works great as a straight up overdrive, but the octave sensitivity is a little finicky. Missing one screw (see photos). Also seems to be missing a battery clip inside, if there ever was one. I’d been using it with a power supply, so I never ran into any issues there.

I would love to see this pedal go on to live with a tech enthusiast that could modify the octave to sustain (Like Maestro ended up doing with the OB-2).

Pedal came fast. Replaced the Big Muff on my board with this. Played a gig the day I got it and got compliments on my tone. Great pedal. Great experience!
