Advanced Tone-shaping Capabilities

Rivera's RockCrusher Recording power attenuator and load box could be your gateway to epic tube-amp tonal bliss. Building on the already popular RockCrusher power attenuator, RockCrusher Recording adds a built-in cabinet emulator with an 11-band EQ, so you can dial-in your tone perfectly — at any volume. If you're not cranking up your tube amp you're not really hearing its full tone! Unfortunately, whether you're at home, onstage, or in the studio, it's not always possible (or comfortable!) to turn up your tube amp to its tonal sweet spot. The solution? Rivera's RockCrusher Recording.

Total tonal control with cabinet emulation

The RockCrusher Recording gives you all the features that made its forerunner an essential tool for tone-savvy guitarists worldwide while adding even greater versatility with all-analog cabinet emulation. An active, 11-band graphic EQ section reflects the typical frequency response range where guitar cabinet speakers live. This allows you to quickly zero-in on virtually any sound you're going after — at any volume! And unlike digital modeling amps and software, the RockCrusher Recording doesn't use DSP to emulate speaker cabinets, it's all analog, so there's no loss of the tonal warmth you love in your tube amp tone.

How do they do it, you ask? Rivera graphs the frequency response of popular classic guitar speakers using real-world microphones and translates that information into a custom graphic EQ curve for your RockCrusher Recording. These graph shape suggestions are intended to give you the tonal nuances of some of your favorite speakers, or they can serve as starting points for nailing a custom tone that's all-your-own.

Perfect for stages and studios of any size

Tube amps interact with the impedance load that a speaker cabinet puts on the amp's output — if you plug your amp's direct output into a recording device, you won't get the tone you expect. By hooking up the RockCrusher Recording to your amp's speaker outputs, it interacts with all of the tubes in your amp — not just the preamp tubes you hear from your amp's direct output. Doing this provides the true articulate and responsive tone you're looking for.

What does this mean for you? You can harness every tiny bit of tone your tubes have been designed to put out, and you get the sound of your amp and pedals, all without worrying about volume. Onstage, the decreased stage volume allows for better monitoring situations and lets your front of house engineer mix your signal without fighting your stage levels. In the studio this means you get to lay down no-compromise guitar tone without bleeding sound into other mics. You paid for every last tube in your amp, use them!

Rugged inside and out for years of use

The RockCrusher Recording is constructed of 16-gauge welded steel that's perforated on the top and bottom of the unit, allowing for convection-type cooling to dissipate heat. Large, heavy-duty knobs and switches are easy to use and super durable. Inside, Rivera uses industrial grade components that stand up to the heat as well as the rigors of the road, making it as capable on a world tour as it is in your studio. Imagine your guitar rig transport whittled down to your favorite amp head and a RockCrusher Recording — not only do you get to play the tone you want, the speaker emulation means you can leave the speaker cabinet at home!

Rivera RockCrusher Recording Features:

  • Power attenuator helps keep your volume down without killing tone
  • Built-in active 11-band EQ gives you an analog speaker emulator
  • 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
  • Tonally transparent so you hear your amp, not the RockCrusher
  • 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

Crushingly great tone!

Had this for a couple if years now. This is an awesome piece of gear. Only used in my home studio and ALWAYS in between my AFD 100 and my Laney 2x12. This thing rocks! Stick a 57 and XR1 on my cab, out the level down to just above conversation levels and have tone for days! If you can afford one, go for it! This will change your life!

Short and Sweet

1. All of the reviews are correct. 2. All of the videos you watch on this are correct. (Pete Thorn has a really good one to watch when you get done with the Sweetwater videos) 3. This thing is incredible. 4. Makes no difference what tube amp you attach it to, your amp WILL sound great. 5. I will never play without one again! 6. the quality build feels like it will last a lifetime.

Truly Amazing

Rivera's genius in this device is the perfectly calibrated EQ that can be used to fine tune and shape what ultimately goes into your PA or DAW to match what you are hearing while playing directly through your amp / cabinet. You can set up a consistent tonal quality across any and all devices and speakers that your guitar passes through. What this means is that when I play through my combo amp speaker alone or when I plug into my external cabinet (note: my combo amp and cabinet all have matched Celestion 12" Vintage 30s), or when I am running through the mixing board / PA, or even when I am recording and listening through my DAW studio monitors or headphones -- without miking the amp -- my carefully crafted guitar tone always sounds the same! (notwithstanding any slight coloration that may be added by the PA or DAW itself). And with attenuation, that same great tone stays consistent at any volume level! Also like to add that I have been buying gear from Sweetwater for over 5 years now and I want to send a special thanks to my Sales Engineer Ryan Murray for all the great customer service!

WORKS AS ADVERTISED

1st, Thanks to Nick Church. As usual, Nick excels in follow up and follow through. I always deal with Nick exclusively. I ran it through my Quinn OD Heaven ( Ser. # 001 a D-killer! ) , my Triple Drive Supreme, My Redplate Magic Dust and my Mark 5. It delivers as advertised. I considered an Aracom but Sweetwater is reliable and awesome with any issues after delivery. Watch the video by Pete Thorn and that's what you get. Easy to use. Also sounded great through my DAW.
