Ampex Grand Master II - 1980
Professional Studio Quality Audio Cassette by Ampex Corporation. CA, USA.
Made in the USA, Redwood City, California, for the Canadian market and distributed by Ampex Canada. This just makes it rarer.
Note: Extremely small number available and it's just... RARE, although not priced that way! Similar rarities are priced much, much higher.
