Neural DSP
Neural DSP is the Finnish software and hardware company that has quickly become the leader in hyper-realistic, high-fidelity digital modelling, particularly for modern metal and progressive rock guitarists. Their philosophy is centred on creating incredibly accurate archetype modelling technology, capturing the exact feel and dynamic response of legendary valve amplifier circuits. Their most influential products are the Quad Cortex, an ultra-powerful, compact floor modeller that features a Neural Capture function (allowing users to create profiles of their own gear), and their suite of industry-leading Archetype software plugins (e.g., Archetype: Plini, Archetype: Rabea). The Quad Cortex offers an unparalleled feature set, including sophisticated routing options and built-in studio-quality effects. Used by world-class producers and guitarists, a Neural DSP Quad Cortex provides the ultimate, flexible solution for touring and studio work, delivering impeccable tone and digital versatility.
