What is it that makes the Fostex cassette tape one of the great cassette tapes ever made? It has nothing to do with fidelity, response, or any of those fancy recording engineer phrases. No, the reason you can sell these in Japan for $50.00, is because of the way that they look.
If you look closely at this cassette tape you will notice that the reels that hold the actual tape are designed to look like old reel-to-reel tapes. They have the exact same look. So what happens when you find 6 cases at your local Goodwill store selling for $4.95 a case? You buy them all, thank someone, and then keep moving.
