Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Universal Audio UAD Ruby '63 Top Boost Amp.

Setup and maintenance

  • Owners suggest placing modulation and time-based effects either before or after the UAD Ruby '63, depending on whether they handle line level inputs.

    Source
  • Users recommend dialing back treble and bass on the brilliant channel to address a mid-scooped sound, suggesting the need for a mids knob for better control.

    Source

Features and functionality

  • The stereo output is designed to mimic two Vox cabs panned, offering an enhanced stereo experience during recording.

    Source
  • The Ruby's lack of post-recording malleability is seen as a limitation for those not regularly gigging or requiring flexible recording setups.

    Source
  • The Ruby '63 includes 6 built-in impulse responses (IRs) that can be disabled to use external IRs in the signal chain later.

    Source

User experience

  • Some users report issues with the vibrato channel and app connectivity, potentially indicating manufacturing inconsistencies.

    Source
  • Owners appreciate the Ruby '63's dynamic and open tone, particularly noting the brilliant channel's chime and the pedal's authentic gain response.

    Source

Use cases and applications

  • The pedal is often used at the end of the signal chain like a traditional amp setup, enhancing its appeal for both live and recording environments.

    Source
  • Ruby is preferred for playing through a real amp setup without a computer, while Morgan is favored for recording flexibility.

    Source
  • Ideal for recording directly into a DAW, the Ruby '63 is favored by users who previously recorded with a Vox AC10 through a load box for its similar response.

    Source

Comparisons

  • The Morgan Suite offers versatility with British, American, and boutique amp models, unlike Ruby, which some find limited to its Vibrato model for broader tonal range.

    Source
  • Nembrini's Vox AC30 emulation is noted for being affordable and often on sale, offering a budget-friendly alternative to Ruby's $399 price tag.

    Source
  • The Walrus Audio ACS-1 offers more versatility with MIDI and headphone jack, but the Ruby '63 surpasses it in pure sound quality, mimicking an actual Vox amp more accurately.

Critic Reviews

Universal Audio UAD Dream '65 Reverb, Ruby '63 Top Boost and Lion '68 Super Lead Amplifier plugins review | Guitar World

guitarworld.com

Universal Audio's Ruby '63 Top Boost Amp plugin delivers an impressive modeling of the classic Vox AC30 with a friendly user interface that simplifies tone shaping. Users will appreciate the quick access to presets and the versatility of added mod options. However, it’s not without its drawbacks; the steep full retail price is a concern, especially considering the necessity of a DAW to launch the plugin, limiting standalone use. Additionally, the lack of Unison versions for Apollo users and fixed mic choices may deter some purists. Overall, it’s a fantastic tool for recording and practice, but be wary of the price tag.
