DESCRIPTION 

Get the British Invasion Tones that Inspired Generations

The UAFX Ruby '63 Top Boost Amplifier pedal gives you the quintessential British valve amp beloved by artists and producers for over 60 years, from Queen to U2 to Radiohead. Built on powerful dual-engine processing and UAD modeling expertise, the Ruby '63 effects pedal delivers choirboy cleans, complex overdrive, and classic vibrato.

Experience British Tube Amp Tones, Stage and Studio

Whether it's replacing your amp rig and going direct to front-of-house on stage, or recording tracks into your DAW — Ruby '63 gives you the inspiring, album‑ready tones of an expertly miked "golden unit" vintage tube combo, within seconds.

Explore Normal, Brilliant, and Vibrato Channels

Ruby '63 is the only stompbox that 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 here.

Push the Limit with Classic Boosts

Ruby '63 packs classic boosts, right onboard. Namely, the legendary '60s Dallas Rangemaster germanium treble booster and the preamp of a '70s Maestro EP-3 tape delay.* Just flip the Boost switch for searing layered tones that put IR-based amp modelers in the bin.
