Frippertronics

Frippertronics is a tape looping technique used by English guitarist Robert Fripp. It marked the first real-time tape looping device, evolving from a system developed in the electronic music studios of the early 1960s by composers Terry Riley and Pauline Oliveros and made popular through its use in ambient music by composer Brian Eno, as on his album Discreet Music (1975). The effect is now routinely found in many commercial loop station guitar digital effects boxes such as the Boss RC-3.

'Frippertronics is a term referring to the analog delay and looping technique developed by Robert Fripp, using two reel-to-reel tape recorders. It was introduced to Fripp by Brian Eno and first used on their album "No Pussyfooting" in 1971. This technique, which involved two tape machines, allowed for real-time recording and playback, creating a looped and delayed sound.'
