The WAZA Core is a seriously clever piece of kit for tube amp owners. It lets you nail that cranked amp tone at manageable volumes, and the recording features are surprisingly good. If you're tired of miking cabs or want to dial in a consistent, studio-ready sound, this is a game-changer – particularly for players with high-wattage amps.

Frequently Asked Questions
The profiles are designed to mimic key characteristics, but subtle tonal differences will still exist. It's a close approximation, but not a perfect clone of every amp.
It's designed for genuine tube amps to leverage the reactive load functionality. While you *can* connect a modeling amp, you’ll primarily benefit from the recording features, losing the reactive load benefits.
The 'Combo' setting emulates a traditional combo amp's speaker interaction, while 'Stack' simulates a 4x12 cab with a power amp. Choose based on your amp's physical setup and desired sonic response.
