The UAFX Ruby ’63 Top Boost Amplifier pedal delivers the quintessential British tube amp tones that defined the sound of the British Invasion. Built on Universal Audio’s powerful dual-engine processing and world-class UAD modeling, it recreates the Normal, Brilliant, and Vibrato channels of a “golden unit” vintage combo. With authentic cabinet and mic emulations, onboard boosts, and deep customization via the UAFX Control app, Ruby ’63 provides album-ready tones for stage and studio.
