The UAFX Ruby '63 Top Boost Amplifier pedal captures the legendary British valve amp sound that has defined rock music for over six decades, from Queen's stadium anthems to U2's atmospheric soundscapes and Radiohead's innovative textures. This powerful stompbox harnesses UAD's renowned modelling expertise and dual-engine processing to recreate the choirboy cleans, complex overdrive, and classic vibrato that made the original amp a studio and stage favourite.
Ruby '63 stands apart as the only pedal offering all three channels from the original amplifier - Normal, Brilliant, and Vibrato - allowing musicians to access the full tonal spectrum with a simple switch flip. The pedal excels both as a complete amp replacement for direct-to-FOH performances and as a recording solution, providing album-ready tones that sound like an expertly miked vintage tube combo straight out of the box.
Built-in classic boosts include the legendary '60s Dallas Rangemaster germanium treble booster and the preamp circuit from a '70s Maestro EP-3 tape delay, accessible via the onboard Boost switch for those searing layered tones that cut through any mix. The UAFX Control mobile app expands the pedal's capabilities further, offering custom artist presets, preset management, and deeper exploration of the amp that sparked the British Invasion.
