Mesa Boogie Powerhouse Reactive Amp Load Attenuator 4 Ohm

Written by

Cian Hodge

All modern Mesa Boogie amps feature some form of attenuation, as well as an incredibly realistic CabClone IR guitar cabinet emulation. The PowerHouse combines these two top class utility features and pushes them to new levels of depth and tone quality. Mesa Boogie only put their name on the very best amps and utility devices in the world, so you know you're in good hands here.

This is a standalone attenuator capable of producing the sweetest tube amp character at lower volumes, either running the signal into a speaker, into a mixing desk when performing without a cab or straight to an interface for recording.


Under normal circumstances, you're only going to get the best tube tones when your amp is pushed to saturation at a loud volume. Sometimes it's simply not possible with the likes of a 100W amp. The PowerHouse's Reactive Load Circuit + is better than ever, and lets you achieve pure, crunchy tones while protecting your amp's power section. It'll slot right into any setup and accommodates stereo speakers thanks to two parallel line outputs. 

CabClone IR

The Powerhouse provides you with the option of playing through your tube amp without a speaker cabinet. This is ideal when travelling light, saving you the trouble of lugging round a heavy speaker cab to gigs. It also helps to streamline your recording setup, with the device small enough to be placed on your desk or on the top of an amp. Choose between three speaker voicing options: Normal, Bright or Warm to suit your tastes.
