It’s basically a free plugin that you “profile” your amp through. Think of it as a kemper ( but much better and more versatile) in a free plugin form. It is really incredible. Several guys have done null tests comparing profiles of their amps with the kemper, tonex, and now NAM, and NAM is by FAR the closest. I mean they almost null out completely compared to the real amp…. I’d pay you big money to download this and give it a shot, im sure many would here too.
They have a pretty solid Facebook group going, I would check it out, download some models ( now on tonehunt.org I believe is where they upload them now) and see for yourself.
I can’t remember who said it but they were dead on with the way to describe the users of this and the vibe of the group: it’s very android vs iPhone. For those that have been on the forum they will probably get what I’m saying, it’s just very…. Android haha. The entire plugin is open source at this time too, so it’s kind of the wild Wild West with it right now, but it is no doubt to me the real deal.
This dude does a pretty good job of explaining it, shows some tones, and does a null test for you to see just how accurate this thing really is. The video is all time stamped so scroll to the sections you would like.
