Neural DSP is no stranger to delivering high quality amp modeling – see its stellar roster of plugins for evidence of that. So when the Helsinki-based firm showed up to last year’s NAMM with the Quad Cortex floor modeler, you’ll understand we got pretty excited about it – in fact, the whole guitar-playing world seemed to get positively giddy over the prospect. Not just because a revered software company had released its first hardware product, but what lay within its aluminum unibody.

From the off, the Quad Cortex promises unrivaled power in such a small footprint that Neural DSP calls it “the most powerful floor modeler on the planet”, stuffed with 2GHz of dedicated DSP power straight out of its Quad-Core SHARC processor.
