VOX

Vox is a musical equipment manufacturer which is most famous for making the Vox AC30 guitar amplifier.
Once The Beatles became tied to Vox amplifiers (a deal was struck early in their recording career whereby they would be provided Vox equipment for exclusive stage use), the quest for more power began. John Lennon’s first Vox was a fawn-coloured twin-speaker AC15, while George Harrison’s was a fawn AC30 with a top boost unit installed in the rear panel.
