When The Beatles’ Abbey Road album was being recorded, some 50 years ago, the band were mainly using Fender amps as can clearly be seen in their last live performance on Apple’s Savile Row rooftop on 30 January 1969. 

Back in ’66 and ’67, though, Vox amps still figured heavily in the studio – not necessarily the AC30s of their earlier days but some new models that the British company supplied to the band. These were the UL 700 series of hybrid amps, which had a solid-state (transistor) preamp with valves in the output section and featured three-band EQ, built-in distortion (fuzz), tremolo and reverb.
