For guitarists who crave the rich, organic tones of a tube amp at its true sweet spot but struggle with volume constraints, BOSS has delivered an innovative solution—introducing the WAZA Tube Amp Expander Core. This powerhouse device is a compact reactive load box designed for seamless direct recording, volume control, and enhanced playability at any level. Whether you’re tracking in the studio, practicing at home, or looking for pristine direct-to-mix sounds, this new addition to the WAZA family brings high-end versatility and studio-grade tone shaping straight to your rig.
Powerful Tube Tone, Anytime, Anywhere
A well-driven tube amp brings out the best in a guitarist’s sound, but real-world limitations like volume restrictions or lack of isolation booths often get in the way. The WAZA Tube Amp Expander Core bridges that gap by offering a reactive load solution that captures the full output of your amp while preserving its natural dynamics and responsiveness. Now, you can push your amp’s power section without shaking the walls—perfect for bedroom practice, gigging musicians, and studio professionals alike.
Studio-Quality Direct Recording & Speaker Cab Emulation
Recording tube amps has never been easier. The WAZA Tube Amp Expander Core is designed to take your raw amp tone and refine it with premium cabinet emulation and microphone modeling. This device gives you access to:
- 22 BOSS cabinet emulations
- Five classic microphone types, two of which can be blended simultaneously
- 10 premium Celestion® Digital IRs preloaded
- 64 user slots for custom IRs from your own library
Fine-tune your mic placements, distances, and levels with the WAZA Tube Amp Expander Core Editor, ensuring you get the perfect mix-ready tone every time you record. Whether you’re tracking tight rhythm parts or expressive lead lines, this unit ensures clarity, depth, and precision.
Seamless Volume Control with Integrated Reactive Drive Power Amp
Low-volume practice doesn’t mean compromising tone anymore. With an onboard 30-watt reactive drive power amp, you can dial in “sweet spot” amp tones at home-friendly levels without losing the warmth and character of your cranked amp. Hook up an external speaker cabinet (4/8/16 ohms supported) and enjoy a full-bodied sound at controlled volume—ideal for late-night jam sessions or controlled stage monitoring.
Mix-Ready Sound with Zero Hassle
One of the standout features of the WAZA Tube Amp Expander Core is Mix Assist—a function that helps shape your recorded tones to sit perfectly in a mix. With three selectable sound contour curves and transient control, your guitar tone will sound polished and professional, even with minimal post-processing.
In addition, the Air Feel feature recreates the spacious, natural resonance of an “amp-in-room” sound, utilizing advanced BOSS spatial technology. Unlike traditional room mics, which can sometimes be inconsistent, this feature delivers an immersive, three-dimensional tone every time you play.
