The Radial StageBug SB-1 is a compact active DI box designed to deliver a clean, consistent signal from acoustic instruments, basses, keyboards, and other high-impedance sources straight to a mixing desk or audio interface. Built for reliability on stage and in the studio, it combines simple operation with professional-grade performance in a pedalboard-friendly format.
Its active circuitry ensures strong signal integrity over long cable runs, preserving clarity and detail while reducing noise and signal loss. The SB-1 is especially well suited to passive instruments, where its high input impedance helps retain natural tone and dynamic response without sounding thin or compressed.
A rugged steel enclosure protects the electronics from the demands of touring and live use, while features such as a ground lift switch help eliminate hum and interference in challenging stage environments. Phantom power operation means no batteries are required, keeping setup simple and dependable.
Ideal for musicians who need a straightforward, space-saving DI solution, the SB-1 offers transparent sound, dependable build quality, and consistent performance night after night.
