UAD Ruby '63 Black Friday pricing runs 67% off, bringing the Top Boost amp plugin to $49 until Nov 30, 2026.
The UAD Ruby '63 Top Boost Amplifier is a native amp simulator plugin from Universal Audio. It is based on the company's UAFX pedal and aims at British valve amp tones, the sound Universal Audio ties to artists from Queen to U2 to Radiohead. The artist names are not an endorsement.
The maker says it covers choirboy cleans, complex overdrive and classic vibrato effects, with boosts, room sound and mic'd speaker cabs built in.
It runs in your DAW, and Universal Audio states that no Apollo is required.
Three, taken from the original amp: Normal, Brilliant and Vibrato. Universal Audio describes the range as running from mellow to chime to grind.
You switch between them like flipping channels on the real amp, so one plugin instance covers three flavours of Top Boost tone.
Flipping the Boost switch gives you a choice of two boost emulations: a germanium treble booster modeled on the Dallas Rangemaster from the 1960s, or the preamp section borrowed from a Maestro EP-3 tape delay dating to the 1970s. The maker says they give layered tones that add character to the amp.
There are six speaker cabinet setups, each with its own mic and room sound:
That gives you ribbon and dynamic mic choices without placing a single mic yourself.
A set of expert presets covers rock, pop, country, funk and more. Load one to start recording quickly, or use it as a starting point and tweak the controls to fit your playing.
The maker lists pop, rock, metal and country among the styles the amp suits.
If you track guitar in the box, the cab and mic choices come already placed, which keeps the signal chain short: amp, cab, room, done.
Universal Audio's feature list for the UAD Ruby '63 plugin:
Yes. The UAD Ruby '63 Top Boost Amplifier Black Friday deal is 67% off, priced at $49, and ends Nov 30, 2026. It is the native plugin version of the amp from Universal Audio.
Universal Audio says the plugin is based on its award-winning UAFX Ruby '63 pedal. It carries over the controls of the Top Boost amp it targets, plus the boost effects, room sound and mic'd speaker cabs.
No. Universal Audio states that no Apollo is required, because this is the native UAD Ruby '63 plugin. You load it in your DAW as a guitar amp simulator and dial in the tone from there.
It has six cab setups: Silver, Blue, Green, Blue Mod, Match and Gold. They use Celestion speakers in 2x12 or 1x12 configurations, mic'd with a 57, a 160 ribbon or a 421 dynamic, plus room sound.
