Steven Atkinson released Neural Amp Modeler, a free amp profiler based on the Neural network emulator for guitar amplifiers, available in VST3 and AU plugin formats.
Neural Amp Modeler is a freeware amp profiler developed by Steve Atkinson and has been making quite a splash. Users can profile their own amps, stomp boxes, and any other gear they might see fit. You can also download a plethora of these profiles and models for your own productions.
At its core, it works similarly to the Kemper, Quad Cortex, and any other modeler using amp profiles compared to algorithmic processing. You get the benefit of superb response, which is often lacking in amp sims.
NAM’s sound quality is absolutely killer, and the latest version brought a much-needed noise gate. There are some occasional issues with the included IR loader, but something like NadIR from STL Tones more than suffices.
The community around NAM has built an impressive collection of models. There very well could be some paid packs in the future, but in the meantime, you have options like the Peavey 5150, a smattering of ENGL amps, and a bunch of stuff you typically don’t see in most amp suites like Sovtek or Ceriatone.
System requirements for NAM are fairly light. You’ll need to run your host at 44.1 or 48KHz, and it needs to be a 64-bit host.
