Radial Headload Prodigy

Combination Load Box & DI


About this item



The Radial Headload Prodigy is a combination load box and DI that lets you drive your guitar amp at a higher gain in order to maximize the tone, yet produce a lower stage volume when needed.

  • Load box with selectable output levels or complete attenuation
  • Drive your amp hard for the best tone
  • Can handle up to 100 watts RMS
  • Balanced JDX direct out feeds the PA or a recording interface
  • Built-in headphone amp for practicing

Sound loud, play quiet

With the Headload Prodigy, you can crank your amp to the sweet spot while keeping output levels in check, allowing you to retain your optimal tone when performing, recording and practicing. The Prodigy can pass 25%, 50% or 100% of the signal from the amp head to the speaker cabinet, or it can also be used without a speaker cabinet for completely silent recording. This is particularly useful in small venues where the speaker cabinet on stage may conflict with the sound in the room, and it’s also great for silent recording where you want to take advantage of ‘high power’ amp distortion without upsetting the neighbors. A balanced DI output features Radial’s popular JDX Reactor circuit, which emulates the tone of a 4×12 half stack for a realistic and consistent tone through the PA or when connected to a recording interface.

The Headload Prodigy is a device that is intended to simulate the sound of a guitar cabinet and allow the user to reduce the speaker output to 50% or 25% on stage or perform without noise in the studio. That said, the following specifications do not provide any truly significant information as it is completely dependent on the amplifier and speaker cabinet in use. As such, we ask you to please review with the awareness that these measurements are truly subjective in nature.
