Guitar Amp Load Box

Description

The Headload™ is a power attenuator that connects between your amplifier and speaker to capture the dynamics and warmth of your amp at low, neighbor-friendly volumes.

  • Combination load box and DI with speaker emulation
  • Available in 4, 8, or 16 Ohms
  • Can handle up to 130 watts RMS (180 peak)
  • Attenuate down to 1% of total power

Sound Loud, Play Quiet!

Featuring two built-in JDX amp DIs—one pre-EQ and one post-EQ—the Headload eliminates the need to use a microphone to capture the sound from your amplifier. Should you decide to combine the DI signal with a microphone, the Headload is augmented with a built-in Radial Phazer to time-align the two signals to create massive tones. The Headload uses a 6-position rotary switch to set the desired power reduction from unaltered all the way down to complete silence. When the output is completely soaked, the high-quality headphone amplifier can be used for silent 3:00 AM practicing.

The Headload is a device that is intended to simulate the sound of a guitar cabinet and allow the user to compensate for the sound depending on the level that is being produced. 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. The Radial Headload is quite likely the most useful load box ever made.
