MESA/BoogiePowerHouse Reactive Load Attenuator Black 4 Ohm
1/4
Independent shopping perspective
The Korena take
Built around a reactive load, the PowerHouse lets a tube amp operate without a live speaker cabinet when silent use is required, while also serving as an active attenuator in either Load or Speaker mode. The rear 1/4-inch line output can feed an impulse-response player or another amplifier. In Speaker mode, its two 1/4-inch speaker jacks work like the speaker connections on an amplifier. A three-way voicing switch offers Normal, Bright, and Warm settings.
Strong match
Who this is for
- Silent amp operation when a live speaker cabinet cannot be used.
- Routing an amp signal from the rear line output to an impulse-response player or additional amplifier.
- Reducing an amplifier’s output in either Load or Speaker mode.
