If you need to record your favorite tube amp direct, the Rockcrusher Recording is for you! This needed tone tool provides a super safe load for your favorite tube amp and gives you the most powerful all analog speaker emulator. The 11 bands of EQ chosen from 75hz to 4k is where most sought after guitar speakers are voiced. With these tuned 11 band of EQ, you'll be able to mimic most speaker and mic combinations and then make sound even better!! Other analog cabinet simulators usually have a fixed tone with "shades of grey" tone controls. There's a 3 position Pad switch to control the input level which maximizes the headroom of the Equalizer. The Level meter allows you to monitor either the power input or the line output. Each tone control has a red light to be able to quickly see your shape on the darkest stages. You can also completely bypass the EQ section with the flip of a switch. Rivera will be continually graphing speakers and mic combinations and posting results here.

Not only can you use the Rockcrusher recording as a load box and cab emulator, you can also use it's power attenuation section just like the standard RockCrusher. The Rockcrusher has quickly become the most recognized transparent power attenuator and here is why: Maintaining the natural amp tone is the challenge for all power attentuators. However, we built into the RockCrusher a reactive load network for proper speaker-amplifier interaction. Rather than a purely resistive load like many of the other power attenuators on the market, the Rock Crusher ensures that the amplifier and speaker see each other in a proper relationship of impedance and inductive/capacitive reactance. This translates to a superior tone, regardless of level. To enhance tonal balance, warmth, and shimmer, at ultra low volumes, there is an Edge and Warm switches that put you in total control of the final output.

In addition to providing superior tone, impedance matching is critical for your tube amp's health and longevity. We gave the RockCrusher an 8/16-ohm selector switch so you can use either value to accurately match your cabinets and amplifiers. Massive thermal capacity with convection cooling allows it to handle 120watts of Tube power with ease.
Rivera have also built in features that ensure the Rock Crusher is easy to use both onstage and in the studio. For bypass on the fly, which lets you use the amp with a speaker cabinet when full output level is desired, we included a front-panel full bypass switch that removes the load entirely. When low speaker volume is desired, there is a Studio position of the Attenuator Level Selector that enables the Studio Level control to adjust from low to quiet output--perfect for home, project, and studio recording.
Balanced XLR and unbalanced " phone jacks with a convenient front-panel level control allow interfacing with practically any audio equipment. Two Speaker jacks allow easy connection with up to two speaker enclosures.
Bullet-proof construction, a standard feature of Rivera equipment, is also engineered into the Rock Crusher: Within the 16-gauge welded steel chassis of the RockCrusher, heavy-duty and rugged industrial-grade components used throughout, designed to give you years of reliable, cool-running service.

I use this unit to tame my EVH 5150 50 watt amp. It sounds great at any volume and its so nice to be able to crank an amp up and control the overall volume. I set my amp volume at 10 or 11 o'clock and attenuate from there. The Rockcrusher doesn't get hot at all and using this unit as a load box, attenuator or direct to the PA works wonderfully. Highly recommended since you can still use your 50 or 100 watt amp with no worries about turning down. This unit does not mess with your tone at all. Overall I am very happy with this piece of gear.

I use this with my Vox ac30 HWH and can now set the amp as loud as I need it for the tone I want without breaking ear drums or having the sound man hate me. This is great as an attenuator or using direct into my PA system for recording or live playing. The speaker emulator is incredible and I can't even tell the difference between my alnico blue cab or the emulator when set to their recommended settings. They have tons of recommended settings to use for various speakers or you can fine tune it to your own liking. The only thing that would make this better would be an optional case.

Performance Warranty Banner

Protect your investment with the Long & McQuade Performance Warranty

A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.

Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.

How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
  • Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
  • Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
  • No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
  • Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
  • Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
  • Loaners Available: A loaner product may be given while the product is being repaired.
  • Power Surge Protection: Your product is covered even if damaged from a power surge.
  • Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
  • Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.

Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.

Purchasing additional years of coverage

Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.

If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:

  • NEW products: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
  • USED products: 4% of the current new selling price to increase the warranty from 3 months to 1 year. 4% for each additional year.
  • GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
  • BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
