Boss WAZA Tube Amp Expander Core Loadbox & Cab Sim

The Boss WAZA Tube Amp Expander Core is a comprehensive loadbox and cabinet simulator designed specifically for guitarists who want to capture the authentic sound and feel of their tube amplifiers at manageable volume levels. It functions as an all-in-one recording and practice solution, allowing players to connect their amp's speaker output directly into the unit, apply high-quality speaker cabinet emulations and studio effects, and output a polished signal ready for recording interfaces or headphones. Key features include Boss's proprietary Tube Logic design with a selectable reactive load that preserves the natural interaction between amplifier and speaker. The unit supports tube amplifiers rated up to 100 watts and includes a built-in 30-watt reactive drive power amplifier for connecting to external speaker cabinets at bedroom-friendly volumes. For recording, it offers 32 premium cabinet emulations (including Celestion® Digital IRs), five selectable microphone types with dual-mic blending capability, and a suite of studio-grade stereo effects including compression, delay, reverb, and EQ. The Mix Assist function automatically optimises tones for recording contexts, while the Air Feel feature adds natural ambience and dimension to create an 'amp-in-the-room' listening experience. The WAZA Tube Amp Expander Core is ideally suited for home studio musicians, recording guitarists, and anyone needing to practice with authentic tube amp tones at low volumes. Its ten saveable rig settings allow for quick recall of favourite setups, and connectivity includes balanced XLR outputs for studio interfaces, a stereo headphone output, an effects loop, and USB-C for direct computer recording and access to the dedicated Boss software editor. The optional Bluetooth adapter enables wireless control via mobile apps. This unit provides exceptional flexibility, making it practical for everything from silent recording sessions to low-volume rehearsal with a physical cabinet.
