Headload Prodigy™ Specifications

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.
