Hear Your Tube Amp's True Character!

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. Said another way, 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. The solution? Rivera's RockCrusher.





Place 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 that the RockCrusher lets you push your amp to its limits while keeping your volume down. On stage, you'll be able to keep stage volume down for better monitoring and overall sonic clarity. In the studio, you'll be able to record the tone you want without creating bleed into other mics - or your neighbor's house.

The RockCrusher also serves a dual purpose as a load box. Tube amps interact with the impedance load that a speaker cabinet puts on the amp's output - if you plug into your amp and just hook the amp's output to a recording device, you won't get the tone you expect. By hooking up the RockCrusher to your amp's speaker outputs, it interacts with your amp to provide the true tone you're looking for. Perfect for recording studios of any size.

The RockCrusher is built with 16-gauge welded steel and industrial grade components, making it as capable on a world tour as it is in your studio. 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.

Rivera RockCrusher Features at a Glance:
  • 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 like 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 you hear your amp, not the RockCrusher

The Rivera RockCrusher Will Be Your Tube Amp's Best Friend

Rivera RockCrusher

Music Background: Some guy who plays guitar in a band!!
Okay the review of this unit is based on gigging and not playing at home. My stage rig consist of a mesa roadster 2x12 coupled with a TC Electronics G system. Needless to say the mesa can get crushing... read more [+]ly loud when the volume gets around 11 or 12 o'clock. The problem i was having is our band has a crazy low stage volume due to using in-ear monitors and electronic drums and a sound guy who is whiny when we turn up. But most of you know playing a tube amp at super low levels just doesn't get it done. So I purchased the Rock Crusher from sweetwater before our last gig to try it out and the only thing I can say is wow. First words out of my sound guys mouth was " What are you doing differently". Most fun I've had at a gig in a while. The amp finally sounds the way I always wanted it to. The Rock Crusher is a keeper. close [-]

Sweetwater Advice

Brian Cravens
Having tried and owned many of the "usual suspect" power attenuators over the years, my experience with the Rivera RockCrusher was truly an eye opener. This is simply the best power attenuator I have ever used. It really lets the tone of your guitar and amp shine. Find out what it really sounds like to open up your tube amp and let it breathe. My Marshall Plexi has never been happier!

The Rivera RockCrusher is is the finest device of its type in the market place. Period.

Well Made

"This unit performs as advertised. It certainly cuts the DB without affecting the tone of your system. Solid construction. The one thing that disappoints me is that it only has a 16 ohm and 8 ohm ... read more [+]setting. If this thing had a 4 ohm setting, then I could use it in my current configuration. All of my tube amps have a 4 ohm setting, for a reason. As it is I had to reconfigure my speakers and run everything at 8 ohms, not optimal. Give the ohm switch a 4 ohm setting and this thing gets 5 stars. close [-]
