About Boss WAZA-TAE

Be prepared to revolutionize your tube amp experience with the Waza Tube Amp Expander, a groundbreaking device that combines a multitude of professional tone tools in one compact, easy-to-use unit. Designed for both stage performing and studio recording, this innovative product is a variable reactive load box, active analog power stage, mic'd cab emulator, IR loader, and recording interface, all rolled into one.

The Waza Tube Amp Expander is powered by our advanced Tube Logic approach, allowing you to push your amp to its sweet spot and play at any volume while maintaining the core tone and feel you love. With extensive connectivity, built-in BOSS effects, 10 fully customizable rig setups, and deep real-time control, you'll have unparalleled creative command for any scenario.

The Version 2 update of the Waza Tube Amp Expander introduces powerful new DI enhancements. The speaker impulse response support has been significantly increased, extending the number of user IR slots from 4 to 32. Additionally, more microphone choices are now available for the built-in cabs, including a new ribbon mic type, three dynamic/ribbon mic blends, and two different room mic variations.

The Waza Tube Amp Expander is the result of Waza R&D expertise and the ever-evolving Tube Logic approach. It seamlessly complements and extends your tube amp without affecting the tone and response that made you choose it in the first place. This unique device was conceived during the development of the flagship Waza amplifier head and has since become an essential companion for every tube amp player.

The Waza Tube Amp Expander's advanced reactive load section allows you to experience your amp's true cranked-up sound and interactive feel while controlling the volume to suit any situation. Its Resonance-Z and Presence-Z panel controls optimize the impedance interaction with your amp's output transformer, making your amp behave and respond exactly as if it were connected to your favorite speaker cab.

With deep control options, the Waza Tube Amp Expander is a dream command center for both stage and studio. It supports any tube guitar amp up to 150 watts, from vintage combos to modern high-gain heads. Its built-in effects engine and external effects loop bring a wealth of sonic enhancements to your tube amp. Onboard DSP delivers premium sound quality and true stereo operation with class-leading 32-bit AD/DA, 32-bit floating-point processing, and 96 kHz sampling rate.

The Waza Tube Amp Expander also offers intense customization options. Connecting to the dedicated editor software via USB allows you to edit effects and EQs in micro detail. You can select from 22 different mic'd cabs for the direct outputs, each with your choice of nine adjustable close-mic types plus five room-mic types for adding spaciousness and depth. There are also 32 user slots for loading your go-to speaker IRs if desired.

In conclusion, the Waza Tube Amp Expander is packed with breakthrough BOSS innovations, making it an indispensable tool for every tube amp player. Whether you're a stage performer or a studio recording artist, this device is designed to elevate your tube amp experience to a whole new level of versatility.
