Inspired by the legendary 2 x 12-inch combo amplifier that powered the British invasion, Universal Audio’s Ruby ’63 Top Boost amp pedal is loaded with jangle and bite! This pedal is an end-to-end emulation of one of the most iconic British amps of the ‘60s, sporting Brilliant, Normal, and Vibrato channels that deliver everything from chimey cleans to all-out crunch. Guitarists at Music Experience are amazed at how closely the Ruby ’63 recreates the sound of a tube amp recorded in a live room, and this life-like quality comes courtesy of UA’s incredible mic, cab, and Dynamic Room Modeling technology. What's more, each pedal in the UAFX series allows you to bypass your amplifier's preamp when the pedal is engaged via the special "4-cable" mode, supercharging your amp with two additional channels. If you’re looking for even greater control, the Ruby ’63 sports Bluetooth compatibility to connect to Universal Audio’s UAFX app for enhanced editing, access to artist presets, and more!
Ruby ’63 comes loaded with three different channels for a wealth of sonic possibilites. Plus, depending on which channel you’re using, the boost control offers unique way to add some character to your tone!
Normal: Looking for a chimey clean tone? This setting features a high amount of headroom and simplified tone controls. As a nod to the original model, this setting’s only EQ shaping control is the Cut knob — both the Bass and Treble knobs are completely disabled. Turning the boost knob activates a germanium-style treble booster.
Brilliant: The perfect mode for guitarists chasing a ‘60s-style British tube crunch. This setting has the lowest amount of headroom and incorporates an extra tube for boosted treble and gain. In this mode, the boost injects a tape delay-inspired style of preamp gain into your signal.
Vibrato: This setting is similar to the Brilliant channel, but with the addition of a deep, choppy vibrato setting. To keep things smooth and clear, this setting’s boost control adds clean gain.
Part of the Ruby ’63’s magic is found in the dead-on speaker/cab emulations, bolstered by Universal Audio’s Dynamic Room Modeling technology. The Ruby ’63 comes loaded with three cab/mic/speaker settings, seamlessly matched to the three different amplifier modes. Guitarists looking to cover a wide sonic range will love experimenting with the different speaker and amp pairings; plus, when registering the Ruby ’63 with Universal Audio, you get three more free cab sims to play with!
Each pedal in Universal Audio’s UAFX series features a special “4-cable” mode accessible via the UAFX Control app, allowing you to bypass your amp’s preamp when the pedal is engaged for incredibly realistic tube-style tones. By hooking your pedal up to both your effects loop send/return and the front of amp input, you can instantly switch between your amp’s stock tone and your UAFX pedal routed straight into the power amp, effectively adding two extra channels to your amplifier. What’s more, Universal Audio designed this feature with multiple pedal setups in mind — you can connect any number of UAFX pedals in this configuration for multi-channel madness!
Looking for greater control over your tone? The Ruby ’63 is Bluetooth compatible to pair with Universal Audio’s powerful UAFX app. In addition to giving you greatly enhanced editing options, UAFX also includes access to artist tones, custom presets, and more!
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.
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.
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.
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.
