On this day in 1966, The Beatles’ seventh studio long-player, Revolver, was released. Bouncing on from the similarly immersive Rubber Soul album tracked months prior, the band entered EMI's Abbey Road Studios in April 1966 to pursue some highly experimental recording techniques.

At this point in their career, The Beatles were almost exclusively focused on studio recording as opposed to playing live. And with that in mind, they were able to experiment with effects as freely as they pleased without needing to consider how they might replicate the same sounds on stage.

Following the development of the fuzz pedal in the early '60s, stompboxes were increasingly seen both on stage and in the studio. Paul McCartney was photographed using a Sola Sound Tone Bender paired with a blond Fender Bassman amp in 1965, and again during the Revolver sessions the following year. 

John Lennon was snapped in the Revolver sessions using another legendary British fuzz – the WEM Rush Pepbox – paired with a Vox UL/Ultra Linear-series amp, a solid-state/tube hybrid guitar amp design with built-in reverb, tremolo, and distortion effects.

By manipulating recording tape, The Beatles were able to pursue several new sounds. Such novel techniques included using tape loops in a similar vein to how modern loopers can create sample collages, and adjusting record/playback speed in order to alter pitch.

Other groundbreaking sounds achieved through tape manipulation include the chorus-like signal doubling effect known as ADT (Automatic Double Tracking), and reverse effects (which required the bulky reel-to-reel tapes to be turned upside down).

Fortunately, modern digital sampling technology allows guitarists to easily achieve reverse sounds using effects pedals such as the Boss DD-7 Digital Delay and Danelectro Back Talk.

Check out “Tomorrow Never Knows” for some choice examples of these tape-based effects.

Finally… Have you ever wondered why the album was named Revolver? Here, Paul McCartney explains the answer...
