Used Radial Engineering SGI TX + RX Direct Box

Used Radial Engineering SGI TX + RX Direct Box pair in great condition, built to send and return instrument signals over long cable runs with pristine tone. The SGI-TX converts your guitar/bass to balanced line for transmission, while the SGI-RX converts it back to instrument level at the destination—ideal for remote amps, pedalboards, or studio routing. Rugged steel construction, transformer-isolated design, and standard XLR balanced connections deliver low noise and reliable performance.
