Radial Engineering JD-7 Guitar Signal Distribution Amplifier – 1x7 Buffered Signal Splitter for Multi-Amp Routing and Studio/Stage Use

The Radial Engineering JD-7 Guitar Signal Distribution Amplifier is a high-end 1x7 buffered signal splitter, DI box, and reamper system designed for professional studio and stage setups where multiple amplifiers need to receive a perfectly clean, phase-correct guitar signal.

At its core, the JD-7 allows a single guitar input to be distributed to up to seven separate amplifier outputs simultaneously, without signal loss, tonal degradation, or ground loop noise. Each output is driven by a discrete Class-A buffered circuit with transformer isolation, ensuring that every amp receives the same pure, full-frequency signal with maximum headroom and clarity.

Beyond simple splitting, the JD-7 is also a complete signal routing and re-amping hub. It includes a built-in direct box (DI) output for capturing a dry, unprocessed guitar signal for recording, as well as a balanced reamp input, allowing previously recorded tracks to be sent back through the unit and routed to multiple amplifiers or pedal setups. This makes it equally powerful in both live performance and studio production environments.

The unit also features Radial’s signature Drag Control load correction, which recreates the natural interaction between guitar pickups and amplifier input impedance, preserving the authentic playing feel. Additional controls such as phase inversion, ground lift, and output switching give engineers and musicians precise control over complex multi-amp rigs.
