NAM Architecture 2 – A Big Step Forward for Amp Profiling?
Something pretty exciting has been happening in the world of Neural Amp Modelling, and I wanted to take a bit of time to talk through it properly. There’s a new update on the horizon called Architecture 2 (A2), and while it might sound like a fairly dry technical upgrade on the surface, the implications for guitar players could actually be huge.
Before we dive into what A2 actually is, it’s worth taking a quick step back and looking at where NAM came from in the first place.
A Quick Refresher: What is NAM?
Neural Amp Modelling (NAM) first started appearing around 2019 as a project under development. The idea behind it was fairly simple: create a system that could capture the sound of a real amplifier and turn it into a digital profile.
That concept itself wasn’t new. Companies like Kemper had already been doing it for years with things like the Profiler, and more recently the Quad Cortex had joined the party with its own capture technology.
The catch with those systems is that they’re tied to their own hardware. If you make a Kemper profile, you need a Kemper to use it. If you move to another platform later, those captures don’t necessarily follow you.
NAM approached the problem from the opposite direction.
It was built as an open-source platform, meaning the technology was free, the captures were shareable, and nobody was locked behind a hardware paywall. In theory, it made amp profiling far more accessible to everyday players.
The Early Limitation: Computers Only
The first practical NAM setups started appearing around 2022, but there was one big limitation.
You needed a computer.
NAM ran inside a DAW as a plugin, so it was brilliant for recording, but if you wanted to use it live you were essentially bringing a laptop rig with you. For some players that was fine, but it wasn’t exactly the most convenient setup.
The real shift came around 2024–2025, when companies started figuring out how to make NAM portable.
When NAM Hit the Pedalboard
That’s where units like the Valeton GP‑5 and the Sonicake Pocket Master came into the picture.
These little boxes suddenly made it possible to run NAM-style tones on a pedalboard-sized device. Instead of needing a laptop, you could throw one of these units in your gig bag and have access to amp captures wherever you wanted.
More recently we’ve also seen things like the Soran Tiny Stomp pushing that idea even further.
However, there was always a small compromise hiding behind the scenes.
The “NAM-ish” Workaround
Full NAM profiles are extremely CPU intensive. Running them at full quality requires quite a bit of processing power, which smaller and more affordable hardware simply doesn’t have.
So companies found a clever workaround.
When you import a NAM profile into devices like the GP-5 or the Pocket Master, the unit converts the file into a lighter internal format that the hardware can actually run.
The result is something that sounds incredibly good — more than good enough for most uses — but technically it’s not running the full-fat NAM profile that you would get inside a computer.
You’ll often see comments online from people pointing out that the bit-rate or fidelity isn’t identical to the DAW version. They’re technically right… but at the same time the tones coming out of these little units are already seriously impressive.
For a lot of players, it’s been the perfect introduction to NAM without needing to wrestle with a full computer setup.
Still, there has always been a lingering question in the background:
What if we could run full NAM profiles on smaller hardware?
Enter Architecture 2 (A2)
That’s where the new update comes in.
The NAM developers have been working on something called Architecture 2, often shortened to A2.
In their own words, A2 is designed to be “lighter, better, and slimmer.”
The big goal here is to reduce the processing demands of NAM without sacrificing the quality that made it so exciting in the first place.
If that works the way people hope it will, it could mean something pretty significant:
Full-quality NAM captures running on smaller, more affordable hardware.
In other words, the gap between studio NAM and portable NAM could start disappearing.
When Might We See It?
The early timeline mentioned March 2026, which is right about now. As of writing, the rollout hasn’t quite landed yet, so we may be running a little behind schedule.
That’s not unusual with projects like this.
Realistically, it wouldn’t be surprising if we start seeing A2-powered hardware sometime later in 2026, perhaps around the third or fourth quarter once manufacturers have had time to integrate the new system.
And if that happens, things could get very interesting very quickly.
Why This Could Be a Big Deal
If A2 delivers on its promise, we could potentially see:
Higher fidelity NAM captures on compact hardware
Less reliance on file conversion workarounds
Even more flexibility when combining amp captures with IR cabinet simulations
That would be a huge step forward for the entire ecosystem of budget modellers and portable profiling units.
For players who have been enjoying the convenience of things like the GP-5, Pocket Master, and Tiny Stomp, the next generation could offer the same portability but with even closer-to-the-real-thing tones.
The Bottom Line
Neural Amp Modelling has already come a long way in a fairly short space of time. What started as a computer-only experiment has quickly grown into a platform that’s appearing in pedalboard-sized gear that anyone can afford.
Architecture 2 looks like the next big step in that evolution.
If it works the way the developers hope, we could be heading towards a world where studio-quality amp captures fit inside tiny, affordable hardware units.
And honestly?
That’s a pretty exciting place for guitar gear to be heading.
