Attenuator and Load Box for Tube Amps  

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 Rivera RockCrusher is a must-have.

The Rockcrusher can be placed in between your amp and speaker cab as a power attenuator, or use it in place of your speaker cabinet as a load box while sending its balanced XLR or unbalanced line out to another amp as a slave, or even send its output to a mixer for recording or live performance.

This attenuator is in minty condition.

I also have for sale the 1968 Sound City Mark III Head and the Reeves 2x12 cab loaded with its Vintage Purple speakers that I recently used with this Rock Crusher.
This is a real killer gear!!!
