RARE Vintage 1972 Maestro Sound Odyssey Phase Shifter PS-1 Operating Instructions, Fold-out Catalog, and Advertising Pamphlet for Late Additional Products not in the Main Fold-out Catalog.

The Operating Instructions and Pamphlet would be great to pair with if you have a PS-1 Phase Shifter for use now, or future selling.

The Pamphlet has descriptions and specs on 3 late addition products, including the PS-1. Printed in USA in 1972.

The fold-out Catalog also has descriptions and specs on products offered at the time. Printed in USA in 1972.
All in phenomenal condition! Pages are still crisp. Color still prevalent. There is writing, as you can see, on the Operating Instructions. This was my granddad's when he bought the Maestro Sound Odyssey PS-1 Phase Shifter.
