JD7 Injector™ Specifications

The Radial JD7 is a combination distribution amplifier, direct box and Reamp. As such there are a myriad of specifications that one may look at when determining suitability. The Radial JD7 incorporates 100% discrete parts, class-A circuitry and Jensen audio transformers in the guitar signal path to deliver near perfect unity gain with plenty of headroom and low noise. The fidelity of the audio and 'feel' can only truly be judged by plugging it in and closing your eyes!
