Inspired by the legendary 2 x 12-inch combo amplifier that powered the British invasion, Universal Audio’s Ruby ’63 Top Boost amp pedal is loaded with jangle and bite! This pedal is an end-to-end emulation of one of the most iconic British amps of the ‘60s, sporting Brilliant, Normal, and Vibrato channels that deliver everything from chimey cleans to all-out crunch. Guitarists at Sweetwater are amazed at how closely the Ruby ’63 recreates the sound of a tube amp recorded in a live room, and this life-like quality comes courtesy of UA’s incredible mic, cab, and Dynamic Room Modeling technology. What's more, each pedal in the UAFX series allows you to bypass your amplifier's preamp when the pedal is engaged via the special "4-cable" mode, supercharging your amp with two additional channels. If you’re looking for even greater control, the Ruby ’63 sports Bluetooth compatibility to connect to Universal Audio’s UAFX app for enhanced editing, access to artist presets, and more!
