The Radial JD7 Injector Guitar Distribution Amplifier is the ultimate tool for capturing the full character of your guitar or bass while feeding up to seven destinations simultaneously with absolute tonal integrity.
Designed for professional studios, re-amping workflows, and complex live rigs, the JD7 delivers pristine signal distribution with the clarity, punch, and reliability Radial is known for—making it a cornerstone for engineers who refuse to compromise at the source. At its core, the Radial JD7 Injector is a premium active guitar distribution amplifier built around Jensen transformers and Radial’s renowned Class-A circuitry. It allows a single instrument to be routed to multiple amplifiers, recording chains, or direct inputs at the same time, all while maintaining proper impedance and eliminating signal degradation. A front-panel Drag control lets you precisely load the pickups to recreate the feel of plugging directly into an amp, preserving the natural response of passive instruments. Each of the seven transformer-isolated outputs features individual level control and ground lift, making the JD7 ideal for re-amping sessions, amp shootouts, wet/dry rigs, or hybrid analog-digital recording environments. Whether you’re tracking guitars in a high-end studio or building a complex stage setup, the JD7 Injector provides unmatched flexibility, noise-free performance, and rock-solid consistency in a rugged 19-inch rackmount format.
