The Universal Audio UAFX Ruby ’63 is an amplifier simulation pedal that recreates the iconic British Top Boost tone of the 1960s. It delivers everything from clean, sparkling tones to the characteristic chime, breakup and dynamic response that made these classic amplifiers a favorite among guitarists worldwide.
The Ruby works beautifully straight into an audio interface or PA system, as well as in front of a power amp. With built-in cabinet simulations, room ambience and multiple boost options, it is a powerful tool for both studio recording and live performance.
