Having extra power supplies on hand is never a bad thing, especially when you run your entire rig through a Neural DSP Quad Cortex. Trying to use a damaged power supply simply isn’t an option during your busy gigging schedule. It’s a direct replacement for the power supply that initially shipped with your Quad Cortex. With a Neural DSP Quad Cortex Power Supply, a malfunctioning power supply will never ruin your performance again.
