The Vox AC-30/6 Top Boost model from 1961 - 1968 is the second iteration of this iconic British guitar amp, known for its driving, jangly tone and association with The Beatles, Brian May, The Shadows, and countless other important British Invasion groups. This model added a "Brilliant" channel and two more inputs to the previous model AC-30/4, and sported a redesigned preamp which was much more stable and reliable.

These amps were optionally fitted with the "Top Boost" accessory, a pair of additional tone controls for the Brilliant Channel on a panel which was typically mounted into a hole cut in the rear panel before finally becoming a standard feature and being mounted on the top control panel some time in 1965. The examples you'll find on this page are all of the Top Boost variety, either with the accessory panel (Fawn and a majority of Brown Diamond Cloth amps) or as part of the main control panel (Black Diamond Cloth amps).
