xelent‘s Tape Delay Machine uses two Walkman type tape players, a Realistic Stereo Mate and a Memorex XB, to create a tape delay. It’s Frippertronics on the cheap!
A single tape loop runs through two modified cassettes (each which have had one of their left or right sides removed). The players themselves have had there walls (the two in the center, respectively) filed down, so the tape runs fluently.
The tape (which moves counter-clockwise) travels through the left player (Realistic) where its internal microphone records sound, and then travels to the Memorex which plays back the sound about 3 seconds later.
