Universal Audio Ruby ’63 Top Boost Amplifier Pedal

The Universal Audio Ruby ’63 Top Boost Amplifier is a high-fidelity amp emulator pedal that faithfully captures the classic British Top Boost tones in a compact stompbox. It gives you three authentic channels — Normal, Brilliant, and Vibrato — with dedicated controls for EQ, boost, room ambience, and vibrato depth/speed. Built-in speaker and cabinet simulations make it ideal for direct-to-PA or recording setups, and deep editing is available via the UAFX app.
