## Before you buy

- The listing's specifications are inconsistent: it calls the product an amp expander, identifies its amplifier type as Tube and lists 100 watts output, while its feature text describes a built-in 30-watt reactive drive power amplifier. The feature text says it supports most tube amps rated up to 100 watts but excludes Mesa Boogie Dual and Triple Rectifier models. Confirm amp compatibility and the meaning of the 100-watt figure before purchase.

## A good fit for

- Guitarists seeking reactive-load direct recording with cabinet and mic emulations.
- Players who want stereo effects, recallable setups and XLR or USB-C recording connections.
- Home users who want a headphone output or a lower-level cabinet setup using the built-in reactive drive amplifier.

## Less suited to

- Buyers seeking a standalone guitar amplifier rather than a tube-amp expander and recording processor.
- Owners of Mesa Boogie Dual or Triple Rectifier amps, which the listing explicitly excludes from its stated up-to-100-watt compatibility claim.

## Customer feedback

The supplied rating information is positive overall, with ratings in the four- and five-star categories. The sample is small and contains no written feedback here, so it cannot establish specific strengths or concerns. Treat it as limited context rather than evidence of recording quality, compatibility or ease of use.

## Frequently asked questions

### Can the WAZA Tube Amp Expander Core record directly?
The listing describes direct-recording features, balanced stereo XLR outputs and USB-C audio recording and playback with computers and mobile devices.
### What cabinet and microphone options are listed?
The listing claims 22 BOSS cabinet emulations and five selectable mic types, with two mic types available simultaneously.
### Can it be used for quiet practice?
A headphone output is listed for quiet practice. The listing also describes a built-in 30-watt reactive drive power amplifier for use with a cabinet.
### Which tube amps does the listing say it supports?
The feature text claims support for most tube amps rated up to 100 watts, excluding Mesa Boogie Dual and Triple Rectifier models. The separate 100-watt output specification conflicts with the stated 30-watt drive amplifier, so confirm compatibility and ratings for your setup.
