If you haven’t read my TONEX review, the basic idea behind these AI-based amp modelers is that they use neural learning to capture and recreate amps and pedals. It’s a must-have if you’re interested in jamming or recording with a range of high-quality amp and pedal models. The fact that I’ve placed this plugin first should highlight how impressed I am with it. It’s essentially an open-source alternative to TONEX, which also has a free version covered later in this list. Neural Amp Modeler (NAM) is a free and open-source plugin that allows you to capture and share incredibly realistic amp models, drive pedals, compressors, preamps, and more.
