Waza Innovation for Lovers of Pure Tube Tone

Boss WAZA Tube Amp Expander

A Next-Generation FoundationBacked by Waza R&D expertise and the continuously improving Tube Logic approach, the Waza Tube Amp Expander complements and extends your tube amp with ease, all without affecting the tone and response that you spent ages perfecting. The original idea for this unique device came during the development of the flagship Waza amplifier head.

To test and refine the amp’s AC power voltage and output circuitry in detail, the BOSS team devised a custom load box with capabilities reaching much further than those in any commercially available unit. This innovative design worked so well that it became the logical foundation for developing a next-generation foundation for the modern tube amp player.

Cranked-Amp Tone & Feel at Any Volume

Boss WAZA Tube Amp Expander

Eliminates Any Loss of ToneBy owning a tube amp, you know that it sounds and feels best when it’s cranked up loud and running hot. But if you’re like most of us, it’s a rare occasion to be able to turn up the volume enough to reach the full expressive potential. Load boxes and volume attenuators driven by a tube amp’s speaker output have attempted to solve this volume problem for years. Although they do lower the volume and provide manageable results, they typically introduce elements that change the tone, dynamic response, and distortion character, leaving you with an unsatisfying result.

The Waza Tube Amp Expander’s advanced reactive load section completely eliminates any tone loss, allowing you to experience your amp’s true cranked-up sound and interactive feel while controlling the volume to suit any scenario. A main feature is the Resonance-Z and Presence-Z panel controls, which edit the all-important impedance interaction with your amp’s output transformer. Choosing from sixteen different settings, you can make your amp behave and respond just 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.

Bigtime Rig Control

Boss WAZA Tube Amp Expander

Easily AdjustableWith deep control options, the Waza Tube Amp Expander is an ideal hub for both stage and studio. Ten different rig setups can be stored in the unit, and each includes your custom effects and EQ settings, cab/IR selections, effects loop on/off, MIDI program change (for controlling external MIDI effects), and amp control status (if you have an amp that supports channel switching). Rigs can be recalled with a panel knob, and extra controls are available for reverb and other functions. There’s also a Write button for saving minor adjustments in the heat of a live performance.

Connecting the optional GA-FC foot controller puts full-throttle performance control at your feet. Via a single TRS cable, you have instant access to the 10 rigs, plus real-time control of delay, tap tempo, solo/EQ, effects loop on/off, and amp channel switching. You can also control levels by connecting external expression pedals to the GA-FC. The Waza Tube Amp Expander also supports FS-series footswitches, plus extensive MIDI control for more complex setups.

Effects to the Max

Boss WAZA Tube Amp Expander

Everything You NeedWith its built-in effects engine and external effects loop, the Waza Tube Amp Expander offers a range of sonic enhancements to your tube amp, especially if it’s a vintage model with no effects loop. Onboard DSP provides premium sound quality and true stereo operation with class-leading 32-bit AD/DA, 32-bit floating-point processing, and 96 kHz sampling rate.

Compressor, delay, and reverb effects are on hand, with loads of customizable settings via dedicated editor software. Four different EQs are available for strategically shaping your tone at multiple points in the signal path, and it’s even possible to use one of the EQs as a switchable boost for solos. The external loop offers selectable series or parallel operation, plus support for both line-level devices and standard stompbox effects.

Feed Stage Cabs, Mixers, Recording Devices, & Headphones

Boss WAZA Tube Amp Expander

Complete Tones For Any SituationWhen you’ve dialed in your amp to the level you love, the Waza Tube Amp Expander lets you deliver that complete sound to multiple destinations at once. With parallel speaker outputs, you can drive up to two stage cabs from the integrated 100-watt Class AB analog power stage. Along with providing smooth, non-stepped level control for any connected amp, this rugged power stage also gives you the option to boost your favorite low-wattage amps to stage-ready volumes.

Balanced mono and stereo line outputs include tone shaping from mic’d cab emulation or user IRs, providing ready-to-mix direct signals for the main PA mixer, stage monitors, and recording devices. There’s a USB output too, meaning you get another direct feed for tracking with your preferred music production software. With the dedicated phones output, you can practice with great tube tone without disturbing anyone nearby.

Intense Customization

Boss WAZA Tube Amp Expander

Extra ControlThe Waza Tube Amp Expander works great instantly, but connecting to the dedicated editor software via USB gives you even further creative potential. For a start, you’re able to edit effects and EQs in micro detail. Along with this, you can select from 22 different mic’d cabs for the direct outputs, each with your choice of nine adjustable close-mic types plus five room-mic types for adding spaciousness and depth.

There are also 32 user slots for loading your go-to speaker IRs if you wish. 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 updated as Live Sets for different gigs and recording scenarios.
