Doubling the voltage to 18V gives you better dynamic, but it also creates a better headroom buffer. A lot of professional guitar players start their signal-chain with a stand-alone buffer. Lacerate has an embedded selectable buffer bypass You can change the bypass mode by turning on the power while holding the footswitch.
Summary:
* True Bypass / Buffer Bypass * 2 types of boost options (Clean & Crank) * Dual FET Circuit Design for the most tube-like tone in a transistor design
