BINSON ECHOREC - DRUM DELAY

It’s not easy to reinvent forgotten technology, but after many years of research, we found the lost secrets and brought back the authentic echoes from the 1950s. It’s known for its use in David Gilmour and Hank Marvin’s guitar tones, John Bonham even used it on drums!  

The Binson Echorec provides a unique and distinguishing type of echo supplied by a rotating metal drum where the audio signal is recorded through a magnetic recording head. The Four Playback heads will allow you to choose individual echoes and swells.
