Universal Audio Ruby ’63 Top Boost Amplifier | UAFX

The Ultimate British Tone with the Universal Audio Ruby ’63

For guitarists striving for the classic British sound of the 1960s, there is no substitute for the specific compression and “chime” of a vintage Top Boost amp. The problem is that these original boxes are heavy, loud and high-maintenance. The Universal Audio Ruby ’63 solves this problem by using UA’s award-winning modeling technology. This pedal mimics not only the sound, but also the physical interaction between the tubes, transformers and speakers. From the sparkling cleans of The Beatles to the raw, harmonically rich lead sounds of Brian May; the Ruby ’63 brings the soul of British rock history to your feet.

Why choose the Universal Audio Ruby ’63?

Choosing the Universal Audio Ruby ’63 is a choice for nuance and character. Where many digital modelers often feel “flat” in the highs, the Ruby ’63 retains that specific glassy definition that British amplifiers are known for. For the professional musician, this means you can record directly into an audio interface with results that are indistinguishable from a studio recording with expensive microphones and vintage hardware.

At i4studio, we recommend the Ruby ’63 to anyone looking for not just an effect, but a full-fledged foundation for their guitar sound. With built-in boosts and the ability to save presets, this pedal effortlessly replaces a heavy amp without sacrificing “feel” and dynamic response. It is the most sophisticated British amp emulation available on the market today.

Frequently asked questions (FAQ)

1. Can I connect the Ruby ’63 directly to a mixing console? Yes, the Ruby ’63 includes high-quality speaker and microphone emulations. You can connect the pedal directly to a PA system or audio interface without the need for a guitar amp or speaker cabinet.

2. What does the ‘Cut’ control on this pedal do? As with the original amp, the “Cut” control works the other way around: by turning it open, you reduce the high frequencies. This is essential for taming the bright “chime” when using single-coil elements.

3. Is the vibrato mode on this pedal authentic? Absolutely. UA has modeled the complex modulation of the original vibrato channel in detail, creating that dreamy, floating sound so characteristic of British Sixties pop.

4. Can I use the Ruby ’63 in conjunction with my current amplifier? Sure. You can turn off the cabinet simulation and use the pedal as a high-quality preamp/overdrive for your own guitar amp for extra British coloring.

5. Does this pedal work well with other effects pedals? Yes, the Ruby ’63 is designed to behave exactly like a real amp. It responds superbly to external overdrives, boosts and modulation pedals at the input.
