Anaheim, CA, January 16, 2025—BOSS announces the WAZA Tube Amp Expander Core, a powerful recording and practice solution for tube-based guitar amplifiers. Based on the popular WAZA Tube Amp Expander, this new model offers a streamlined footprint and many powerful enhancements focused on direct recording applications. The advanced BOSS Tube Logic design approach harnesses the complete output of a connected tube amplifier, supported by premium cab emulation and studio processing to craft impactful, mix-ready guitar tracks. The WAZA Tube Amp Expander Core also features an integrated 30-watt reactive drive power amp, allowing users to hook up a speaker cabinet and enjoy “sweet spot” amp tones at home-friendly levels.

A tube-based guitar amp sounds and feels its best when the volume is cranked and its power section is really working. Unfortunately, the levels produced are usually unmanageable for anyone without an isolation booth or very forgiving neighbors. The WAZA Tube Amp Expander Core solves this issue, allowing the user to drive their amp while capturing the speaker output with a reactive load that accurately emulates combo and stack-style speaker behaviors. This isolated signal can then be used for direct recording and low-volume playing situations.

The companion editor software provides a studio playground for shaping the raw amp sound within the WAZA Tube Amp Expander Core. Users can choose from 22 BOSS cabinet emulations and five classic mic types (two available simultaneously), then dial in the ideal blend with position, distance, and level controls. Alternatively, it’s possible to use up to two speaker cab IRs at once, either from the 10 included Celestion® Digital IRs or 64 selections loaded into the unit from a personal IR library.

The WAZA Tube Amp Expander Core contains powerful tools to help achieve world-class recorded tones with no engineering experience required. The Mix Assist function applies one of three sound contour curves with variable transient control, making it easy to record parts that blend perfectly within mixes. There’s also an immersive Air Feel feature that uses BOSS spatial technology to recreate the inspiring “amp-in-room” tone that guitarists love.

Effect processing plays a vital role in shaping great studio guitar tones. The WAZA Tube Amp Expander Core features a series/parallel loop for inserting external mod and ambience effects, positioned after the amp’s distortion for the clearest sound. High-quality internal processing is also available to apply compression, EQ, delay, and reverb within the unit. Users can organize custom setups in the editor—including cab choices and effects—and assign 10 favorites for instant access with the Rig knob on the front panel.

The WAZA Tube Amp Expander Core’s versatile connectivity provides many ways to use rig setups. Players can record directly to music production software over USB or patch into a mixer or audio interface with the stereo XLR output jacks. It’s also possible to hook up an external speaker cabinet (4/8/16 ohms) for daily practice or monitor through headphones with Air Feel for an inspiring spatial experience. The optional Bluetooth® Audio MIDI Dual Adaptor adds wireless capabilities, allowing players to jam with music streamed from a smartphone and use the mobile version of the editor to tweak rigs and load IRs.

Availability & Pricing
The new BOSS WAZA Tube Amp Expander Core will be available for purchase at authorized U.S. BOSS retailers for $699.99 in February.
