UAFX Ruby '63 Amp Review: Universal Audio's Best - Premier Guitar

premierguitar.com

The Universal Audio Ruby ’63 Top Boost Amplifier serves up authentic AC30 tones with remarkable vibrancy and versatility, effectively transforming your existing gear into something extraordinary. Its intuitive interface and innovative features, including a smart speaker toggle, enhance its usability. However, it falls short with the absence of a footswitch for vibrato and limited preset storage. At $400, while it may seem pricey, the pedal’s ability to breathe new life into your sound makes it feel like a worthwhile investment. If you're looking to channel that classic British tone, the Ruby ’63 might just be your ticket to sonic bliss.

Review: Universal Audio UAFX Ruby ’63 Amp Emulator – the ultimate Vox in a box?

guitar.com

Universal Audio's Ruby ’63 Top Boost Amplifier delivers an incredibly authentic Vox sound, capturing the essence of a 1963 AC30 with rich tonal options and a user-friendly design. Musicians will appreciate its versatile cabinet selections and engaging modulation effects that enhance the overall experience. However, the limited preset functionality and steep price tag for a single amp model may deter some. Despite these drawbacks, the Ruby ’63 stands out as a joy to play, making it a worthwhile investment for those seeking classic Vox tones.
