The AI builds it. Not just a preset... a brand new algorithm. No other guitar gear on earth can do this, and it comes FREE with Stratus and Nimbus. --- NEURAL AMP MODELER — 300,000+ AMP & GEAR CAPTURES In partnership with TONE3000, get instant access to a massive community library of Neural Amp Modeler captures — real tube amps, cabs, and gear, modeled with stunning accuracy.
