Mesa Boogie PowerHouse Reactive Load Attenuator - 4 ohm
Additional Photos:
Every experienced player knows there's nothing like a great tube amp running in the power band for Tone, feel and excitement. Be it a 30-watt Combo running 6V6 or EL84s, or a full-blown 100-watt Head cranking with 6L6 or EL34s, nothing compares to the dynamics, expressiveness, fullness and dimensionality of a tube power amp operating "in the zone". However these days, venue volumes are down and neighbors everywhere aren't as tolerant as they once were. That's no reason to compromise your sound and run your favorite amp in its less dynamic idle zone because now Mesa Boogie has got you covered with the PowerHouse Reactive Load Attenuator.
The Attenuator You've Been Waiting For
Aficionados, this is the power attenuator youve been waiting for. One that puts Tone and feel first and includes valuable features you need while preserving the magic of your tube amp in all its harnessed-volume glory.
It start with a reactive Load - an expanded version of that used in Mesa's CabClone IR series, that protects your amp's power section and imparts much the same frequency and response curve and reacts with your amp's power section in much the same way your favorite speaker cabinet does, yet allows you to run silently and safely when a live speaker cabinet can't be used.
Set to LOAD or SPEAKER, you can take a signal out the optimized LINE OUT 1/4" output on the Rear Panel and feed your destination of choice, from Impulse Response players to additional amplification for headroom, consoles for re-amping to effects processors or anywhere an unprocessed signal (no Cabinet Simulation such as that found in the CabClone IR Series) is appropriate.
In SPEAKER Mode, the two 1/4" SPEAKER jacks on the Rear Panel function just as those on your amplifier do. In either case, the Attenuator is active and you can use it to reduce the output of your amplifier safely The Attenuation Control in PowerHouse is full featured and provides a Bypass plus 4 Power Reduction levels, -4, -8, -12 and -16dB, with the lowest setting featuring an infinite attenuation LEVEL control that allows whisper soft volumes and below. A Voicing Switch rounds out the Front Panel and includes NORMAL, BRIGHT and WARM settings on the 3-position mini toggle. Output to your Live Cabinets are covered as well with two 1/4" OUTPUT jacks wired in parallel, so running additional Extension Cabs is easy. The PowerHouse can handle amplifiers up to 150 Watts and is available in 4, 8 and 16 Ohm impedance versions/ratings.

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.
