Delay is perhaps one of the most well-known and often or even over-used effects in music production. Since the early days of rock’n roll recordings in the 50s, tape delay was an important part of the sound: the slapback guitars, the beefed-up vocals. Creative use of tape delay would follow in the 60s with pioneering artists such as Jimi Hendrix and Pink Floyd. About that time, delay also got easier to handle when Philips brought out the Bucket Brigade Device (BBD) chip that could delay a signal electronically, making bulky and fragile tape machines redundant.
