Rivera RockCrusher Power Attenuator and Load Box Gold Edition Brand New 2026

Rivera's RockCrusher power attenuator and load box could be your gateway to epic tube-amp tonal bliss. The tone of a tube amp is directly related to the power of the signal it receives and how much amplification is added by the tubes themselves. In other words, if you're not cranking up your tube amp, you're not really hearing its full tone! Unfortunately, it's not always possible (or comfortable!) to turn up your tube amp to its tonal sweet spot, and that's where Rivera's RockCrusher comes in. Put the RockCrusher between your amp and speaker cabinet, and you'll be able to crank up the tone on your amp while keeping your volume down.

The RockCrusher's reactive load network is constantly maintaining the proper relationship of impedance and inductive/capacitive reactance. In guitar-speak, that means the RockCrusher lets you push your amp to its limits so that your tubes reach their tonal potential all while keeping your volume down. If you play a tube amp and want the ability to get killer tone out of it at reasonable volumes, the RockCrusher is a must-have. Beyond that, this version of Rivera's RockCrusher boasts a gold face for an eye-popping appearance.

8-ohm and 16-ohm modes let you use the RockCrusher with almost any amp/speaker combination
Lets you hear your tube amp's tone as you've never heard it before
Bombproof construction lets you take it to even the wildest gigs
Balanced XLR and unbalanced 1/4" outputs let you easily interface with your recording gear
Tonally transparent so that you hear your amp, not the RockCrusher Gold-face edition.
