Independent shopping perspective
The Korena take
Bring a tube amp into a more controlled stage or studio setup with the WAZA Tube Amp Expander Core. Its variable reactive load box lets you run the amp at its desired setting while controlling volume. Built-in delay, reverb, EQ, cabinet simulations, custom IR loading, and stereo effects extend the rig without adding separate processors. MIDI control and presets support repeatable setups, while the recording interface and XLR line outputs provide routes for recording or front-of-house use.
Strong match
Who this is for
- Recording a tube amp through the built-in recording interface and cabinet simulations.
- Stage rigs needing XLR line outputs, presets, MIDI control, and built-in effects.
- Using custom speaker IRs alongside delay, reverb, EQ, and stereo effects.
Consider the trade-offs
When to look elsewhere
- Tube amps with input power above the listed 150 W maximum.
- Amp or load setups outside the listed 4–16-ohm impedance range.
