Used Universal Audio Ruby Top Boost Amplifier Effect Pedal

Used and in good condition, the Universal Audio Ruby '63 Top Boost Amplifier Effect Pedal delivers authentic British tube amp tones in a compact, pedal-friendly format. Modeled after the iconic 1963 Top Boost amplifier, the Ruby offers true-to-original cabinet emulations, tube gain stages, and reactive speaker load for realistic amp response. Designed for both live and studio setups, it features stereo outputs, selectable speaker cabinets, and adjustable mic positions. The pedal supports bypass modes, including true or buffered bypass, and can be powered via standard 9V DC (400mA minimum). While showing light cosmetic wear from regular use, this unit functions perfectly and is ready to bring classic chime and rich overdrive to your rig. Whether you're chasing Beatles-era shimmer or Brian May-style saturation, the Ruby '63 provides rich tone you can feel under your fingers.
