The British Invasion – now in a plug-in

Ruby 63 Top Boost meticulously models the coveted Top Boost channel of the 1963 Vox AC30, the amplifier that defined the British Invasion sound. UA's circuit-accurate modeling captures every nuance of the original's EF86 preamp tube and Class A power section, including dynamic bias fluctuations and power tube sag that respond to your playing dynamics. The plugin features three custom speaker IRs (Blue, Silver, Greenback) and an interactive tone stack that behaves like the original's "Cut" and "Brilliance" controls. Whether dialing in clean jangle or pushed midrange growl, Ruby 63 delivers studio-ready tones that inspired The Beatles, Queen, and U2.
UAD Ruby '63 gives you the Normal, Brilliant, and Vibrato channels from the original amp — so you can fly to Ireland, London, or Liverpool with the flip of a switch. From mellow to chime to grind, it's all in here, with the unmatched sound and feel of a truly iconic amp.
