Vox amps have had a fantastic reputation from the late 1950s onwards. Their endorsements by the Shadows, and then the Beatles firmly fixed their position amongst far better established brands, and set the 'Vox sound' in the consciousness of the worlds music lovers. And Vox amps do have a great sound! Especially great for chiming chords and stabbing rhythm parts. Even today, the earlier Vox tube amplifiers are still widely used in recording studios for their wonderful tone. As the 1960s turned into the seventies, and rock music got heavier, other British amp manufacturers took the lead - notably Marshall; such amps are great for blistering lead work, but few amps can match the unique 'Vox sound' of an early-mid 1960s Vox AC30.
The story starts with Dick Denny's 15 watt AC15, which the company launched in 1958. This was followed by the 30 watt AC30 a year later in 1959.
