Bringing together a diverse range of professional tone tools for the very first time, the Waza Tube Amp Expander elevates the tube amp experience to a level of versatility for stage performing and studio recording never done before. This amazing device does it all - it's a variable reactive load box, active analog power stage, mic'd cab emulator, IR loader, and recording interface, all-in-one integrated unit that's road-ready and easy-to-use. Waza Innovation for Lovers of Pure Tube Tone Realized with Waza R and D expertise and the ever-evolving Tube Logic approach, the Waza Tube Amp Expander seamlessly complements and extends your tube amp, and all without affecting the unique tone and response that made you choose it in the first place. The initial concept for this unique device came during the development of the flagship Waza amplifier head. To comprehensively test and refine the amp's AC power voltage and output circuitry, the Boss team devised a custom load box with capabilities reaching far beyond those in any commercially available unit. This innovative design performed so successfully that it became the logical foundation for developing a next-generation toolkit for the modern tube amp player. Cranked-Amp Tone and Feel at Any Volume As a tube amp owner, you know that it sounds and feels best when it's cranked up loud and really cooking. But, if you're like most of us, it's a rare pleasure to be able to open up the volume enough to unlock that full expressive potential. Load boxes and volume attenuators driven by a tube amp's speaker output have attempted to solve this nagging volume issue for years. But, while they do lower the volume and provide workable results, they typically introduce artifacts that change the tone, dynamic response, and distortion character, leaving you with an unsatisfying experience. The Waza Tube Amp Expander's advanced reactive load section completely eliminates these artifacts, allowing you to experience your amp's true cranked-up sound and interactive feel while controlling the volume to suit any situation. A key feature is the Resonance-Z and Presence-Z panel controls, which optimize the all-important impedance interaction with your amp's output transformer. Selecting from sixteen different settings, you can make your amp behave and respond exactly as if it were connected to your favorite speaker cab. Any tube guitar amp up to 150 watts is supported, from vintage combos to modern high-gain heads. Intense Customization The Waza Tube Amp Expander works great out of the box, but connecting to the dedicated editor software via USB unlocks even further creative potential. First off, you're able to edit effects and EQs in micro detail. In addition, you can select from 22 different mic'd cabs for the direct outputs, each with your choice of five adjustable close-mic types plus three room-mic types for adding spaciousness and depth. There are even four user slots for loading your go-to speaker IRs if desired. Other tweaks are available too, including MIDI, system parameters, and a loudness contour for big, full tones at whisper-quiet levels. Favorite rig setups can be saved on your computer and organized as Live Sets for different gigs and recording scenarios.
