Universal Audio Ruby '63 Top Boost Amplifier Pedal

Universal Audio UAFX Ruby '63 Top Boost Amplifier Pedal

The "British Invasion" didn't just change music; it changed the way we think about guitar tone. If you’ve ever chased that elusive Vox AC30 chime—the kind that sparkles like a bell but growls like a beast when you dig in—the UA Ruby '63 is your new best friend.

At Tone Tailors, we see a lot of "amp-in-a-box" pedals, but the Ruby '63 is a different animal. Built on Universal Audio’s world-class dual-engine processing, this pedal doesn't just "model" a sound; it behaves like the actual hardware. From the iconic "Top Boost" to the pulsating vibrato, it’s all here.

The Three Faces of British Tone

The Ruby '63 gives you the three quintessential channels of the original "Golden Unit" vintage amps, each with its own dedicated boost circuit:

• Brilliant: Based on the legendary '63 Top Boost channel. This is the home of that famous "chime."
  • The Boost: A perfectly captured EP-3 preamp boost for extra harmonic saturation.
• Normal: Based on the '61 non-top-boost circuit. It’s mellower and takes pedals like a dream.
  • The Boost: A classic Dallas Rangemaster Treble Booster for that searing Brian May/Rory Gallagher lead tone.
• Vib-Trem: The soulful, pulsating heart of the amp. It ranges from subtle movement to aggressive, choppy tremolo.
  • The Boost: A clean, transparent boost to push your signal without coloring the tone.

Legendary Speakers & Room Magic

Universal Audio didn't stop at the preamp. They’ve included their award-winning Dynamic Room Modeling (from the OX Amp Top Box) to give you the feel of a mic’d cab in a real space.

• SILVER: Rare 15W Celestion Silver Bulldogs (warm and open).
• BLUE: The original Celestion Blue Bulldogs (maximum chime and jangle).
• GREEN: Modern Celestion G12Hs (thicker midrange, great for heavy crunch).
• Bonus Cabs: Register your pedal via the UAFX app to unlock three more legendary cabinets (including 1x12 AC15 and 2x12 Matchless options).

Why It’s a Game-Changer for Your Rig

Whether you’re recording direct into your DAW or ditching the heavy tube amp for your next gig, the Ruby '63 delivers:

• Stereo Everything: Massive, wide soundscapes for your delays and reverbs.
• 4-Cable Mode: Integrate it into your existing amp setup to add two "virtual channels" to your current rig.
• App Control: Use the UAFX Control app to customize footswitches, save presets, and even download settings from pro artists.
