Deliver British Tube Amp Tones, Stage and Studio

Whether you're replacing your amp rig and going direct to front-of-house on stage, or recording tracks into your DAW, the Ruby '63 provides inspiring, album-ready tones of an expertly miked "golden unit" vintage tube combo within seconds. This pedal brings the authentic sound of a '60s British tube amp to your setup, perfect for live performances and studio recordings alike.

Explore Normal, Brilliant, and Vibrato Channels

The Ruby '63 is the only stompbox that gives you access to the Normal, Brilliant, and Vibrato channels from the original amp, allowing you to switch between mellow, chime, and grind tones with ease. This flexibility lets you fly to Ireland, London, or Liverpool with the flip of a switch, offering a wide range of tonal options.

Push the Limit with Classic UK Boosts

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

Tailor Your Tone with Built-In Mic and Speaker Pairings

With built-in mic and speaker pairings from UA's award-winning OX Amp Top Box, the Ruby '63 lets you tailor your classic Brit amp tones to perfection.
