Get more control on stage and more tone at home.

The Mesa/Boogie PowerHouse Reactive Load Attenuator puts tone and feel first while preserving the magic of your tube amp in all its harnessed-volume glory. Featuring an expanded version of the reactive load found in the CabClone IR series, the PowerHouse attenuator protects your amp's power section and operates in much the same way as your favorite speaker cabinet does, but allows you to run silently and safely when a live speaker cab cannot be used. Set to Load or Speaker, any signal can be put through the 1/4" line out on the rear panel to your destination of choice, from impulse response players to additional amplifiers. In Speaker mode, two 1/4" speaker jacks function just like those on your amplifier. In both cases, the attenuator is active and can be used to reduce the output of amplifiers safely. A voicing switch rounds out the front panel and includes normal, bright and warm settings on the 3-position mini toggle.


  • Rated for amps up to 150 watts
  • Attenuator Switch provides 4 levels of power/volume reduction, -4 dB, -8 dB, -12 dB and -16 dB
  • -16dB Level Control allows infinite power/volume reduction down from the -16 dB position
  • Speaker/Load Switch – Choose between using your live speaker cabinet or the internal reactive load
  • Normal/Bright/Warm Voicing Switch
  • One 1/4" Input Jack (From Amp Speaker Output)
  • Two 1/4" “To Live Spkr Cab” output jacks
  • Independent 1/4" Line Level “Dry” output jack (exact signal from amp’s speaker output) with Level Control
  • Fan cooled
  • Tall rubber feet - Allow PowerHouse to sit on top of most amps, clearing the handle
