“I am an absolute DI fanatic, owning probably 50+ DIs and preamps. And while they’reall great in specific ways, they all either lack something critical or try to stuff in toomany features, making for an underwhelming or even overwhelming user experience!This is exactly why I wanted to make Mantle. I needed this product to exist. I’m thrilledto say that now it does. And it is absolutely killer.”
