Effects to the Max –
With its built-in effects engine and external effects loop, the Waza Tube Amp Expander brings a wealth of sonic enhancements to your tube amp, particularly if it’s a vintage model with no effects loop. Onboard DSP delivers 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 customisable 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.
Cranked-Amp tone and feel at any volume –
As a tube amp owner, you know that it sounds and feels best when it’s cranked up loud and really cooking. But if you’re like most of us, it’s a rare pleasure to be able to open up the volume enough to unlock that full expressive potential. Load boxes and volume attenuators driven by a tube amp’s speaker output have attempted to solve this nagging volume issue for years. But while they do lower the volume and provide workable results, they typically introduce artefacts that change the tone, dynamic response, and distortion character, leaving you with an unsatisfying experience.
The Waza Tube Amp Expander’s advanced reactive load section completely eliminates these artefacts, allowing you to experience your amp’s true cranked-up sound and interactive feel while controlling the volume to suit any situation. A key feature is the Resonance-Z and Presence-Z panel controls, which optimise the all-important impedance interaction with your amp’s output transformer. Selecting from sixteen different settings, you can make your amp behave and respond exactly as if it were connected to your favourite speaker cab. Any tube guitar amp up to 150 watts is supported, from vintage combos to modern high-gain heads.
Intense Customisation –
The Waza Tube Amp Expander works great out of the box, but connecting to the dedicated editor software via USB unlocks even further creative potential. First off, you’re able to edit effects and EQs in micro detail. In addition, you can select from 22 different mic’d cabs for the direct outputs, each with your choice of five adjustable close-mic types plus three room-mic types for adding spaciousness and depth. There are even four user slots for loading your go-to speaker IRs if desired. Other tweaks are available too, including MIDI, system parameters, and a loudness contour for big, full tones at whisper-quiet levels. Favourite rig setups can be saved on your computer and organised as Live Sets for different gigs and recording scenarios.
