What we say:

At A Glance

The Universal Audio Ruby '63 Top Boost Amplifier Emulation Pedal captures legendary vintage amp tones in a powerful pedal form. Universal Audio have gone to great lengths to ensure that this pedal not only nails that '63 amp sound but also has the flexibility to be used with many different guitars. This isn't your standard amp-in-a-box; if you close your eyes you'd be hard pushed to tell it apart from a real tube amp. As for the tone, think of Queen, U2, and Radiohead type sounds. Also included are live/preset modes and top-class cabinet emulation.

Features We Love:

Excellent Tone for Every Scenario

Looking to leave the heavy tube amp at home but don't want to miss out on the sound? The Ruby '63 can be used straight to front-of-house for a perfect and simple stage solution. It can also be plugged into your recording interface for superb tones with minimal fuss.

3 Channels and Boost

Included in the Ruby '63 are the Normal, Brilliant, and Vibrato channels which sound just like they do on the amp it emulates. It also features a classic sounding Boost for when you need that extra push.

Custom Mic and Speaker Pairings

Featuring UA’s award-winning OX Amp Top Box, this pedal is ready to go right from the get-go. With three 2x12" speaker models to choose from plus additional models available via the UAFX Control app, you can find that perfect sound you've always dreamed of.

Overall Rating 4.5/5 (2 reviews)

Outstanding pedal, If you love AC30’s you definitely won’t be disappointed

james d. - 6/11/2022

Very good for recording-lots of options-through an amp it sounds obviously digital a bit like going from single coil pickups to EMG's
