Robust attenuation and flawless cab emulation

Even if you love HARD, the Waza Tube Amp Expander Core ensures that your family, roommates or neighbors don't have to pay the price for your penchant for loudness. Suitable for tube amps up to 100 watts, the Core delivers efficient power attenuation driven by BOSS Tube Logic. It includes a selectable Reactive Mode knob with Combo and Stack settings to preserve the natural characteristics of your amp. You don't need a speaker. The Core includes 32 lifelike cabinet emulations, including Celestion Digital impulse responses. In addition, 64 user IR slots are available, with support for both mono and stereo WAV files up to 32-bit float/96kHz. You get five selectable microphone types, plus the ability to mix up to two microphone signals to create your ideal studio-quality tone, as well as a deafening cache of premium stereo effects, including compression, EQ, delay and reverb. Finally, there are 10 callable rig settings that allow you to easily save and recall your favorite setups.

All the right connections

Notable are the extensive connectivity options of the Boss Waza Tube Amp Expander Core. For starters, you get balanced L and R Line Out connections, so you can send a clean line-level analog signal to your console or audio interface - in stereo. Plus, a USB port lets you skip the audio interface altogether and send your processed signal directly to your computer for recording, patch editing and IR loading. The Tube Amp Expander Core's flexible FX Loop connections let you choose between series or parallel use and a -10dBV or +4dBu analog signal level. You also have a Phones output for quiet practice with headphones and a To Speaker jack to connect to a physical speaker cabinet.
