Tel-Ray Variable Delay 8.0

One invention involved a tuna can, a motor, and a few tablespoons of cancer-causing oil. The creation: an "Electronic Memory Unit" — a technology, they were sure, that would be of great interest to companies like IBM and NASA.
Though it never made it to the moon, the killer technology that gives Tel-Ray its unique sound was licensed by most every major guitar amp manufacturer. Add an echo to any voice or instrument using the Tel-Ray Variable Delay. It provides lush delay, amazing echo, and warms up your tracks and mixes.
