UAFX Ruby ’63 Top Boost Amplifier
The UAFX Ruby ’63 Top Boost Amplifier is a premium amp emulator pedal from Universal Audio, delivering the legendary British tube amp tones that defined countless classic recordings. Inspired by the iconic “Top Boost” amplifier circuits of the early 1960s, Ruby ’63 captures the chime, breakup, and dynamic response of vintage Class A tube amplification with exceptional realism.
Powered by UAFX dual-engine processing, Ruby ’63 recreates the full character of a cranked vintage British combo amp — from shimmering clean tones and edge-of-breakup sparkle to rich harmonic overdrive. The pedal also includes carefully modeled boost options, speaker cabinet emulations, and room ambience for a complete amp experience directly from your pedalboard.
Designed for both stage and studio use, Ruby ’63 offers authentic feel and responsiveness while integrating seamlessly into modern recording and live performance workflows. Stereo outputs, preset support, and USB connectivity provide additional flexibility for professional setups.
