BOSS WAZA Tube Amp Expander Core Reactive Load Box with 30-Watt Power Amp

The WAZA Tube Amp Expander Core is a professional recording solution for capturing genuine tube amp tones with exceptional quality. Our Tube Logic approach and reactive load design retain your amp’s natural feel and touch response, while premium signal processing makes it simple to create studio-grade recordings.

Advanced features include the Mix Assist tool for ensuring tracks balance perfectly and the Air Feel function that uses BOSS spatial technology to recreate the immersive “amp-in-room” sound. An integrated 30-watt reactive drive power amp lets you enjoy “sweet spot” tones at home-friendly levels.

Supreme Tube Tones at Any Volume

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 captures your amp’s speaker output with a reactive load, emulating combo and stack behaviors. Its 30-watt power amp supports low-volume practice or mic recording, while cab emulations polish the signal for direct recording.

Premium Speaker Sounds

The companion editor software is a powerful platform for sculpting sounds within the WAZA Tube Amp Expander Core. Select from 22 BOSS cabinet emulations and five classic mic types, using up to two mics at once, then fine-tune the perfect blend.

Similarly, up to two cab/mic IRs from the included Celestion Digital IR selection or user IR library can be used simultaneously. A handy time alignment control lets you synchronize IR combinations with precision for a smooth, cohesive tone.

Professional Recording Tools

The WAZA Tube Amp Expander Core provides you with the tools to create professional-quality tracks. Developed alongside top guitarists and engineers, Mix Assist offers sound contour curve and transient control, helping tracks sit flawlessly in the mix.

The immersive Air Feel feature enhances recordings with inspiring “amp-in-room” realism. It uses BOSS spatial technology to deliver two variations rich in depth and dimension, producing a more natural sound than traditional room mics.

Seamless Integration

The WAZA Tube Amp Expander Core enhances your sound with onboard compression, EQ, delay, and reverb. There’s also a series/parallel loop for external effects. Customize setups in the editor and store up to 10 favorites for instant access via the Rig knob.

Enjoy flexible connectivity, from USB recording and mono/stereo XLR outputs to speaker cab and headphone monitoring. With 64 user IR slots, premium Celestion IRs, and optional Bluetooth® functionality, the WAZA Tube Amp Expander Core delivers unmatched versatility for recording guitar.
