Understanding Different NAM Types: Nano, Feather, Lite, and Standard

If you’ve spent time browsing NAM captures on TONE3000, you’ve probably noticed that Neural Amp Models come in a few different versions: Nano, Feather, Lite, or Standard. They’re all modeled using the same tone-capturing process that powers Neural Amp Modeler (NAM), but they vary in how detailed the model is, how much CPU it uses, and how accurate it sounds.

Whether you’re using NAM for high-end studio production or jamming on a portable setup, understanding these model types helps you choose the best balance between tone quality and performance.

What Makes Each NAM Type Different

NAM models are created by training a neural network on the behavior of a piece of outboard gear, an amplifier, pedal, or full signal chain. The person training the neural network can choose from several different formats that vary in size and complexity. These differences are what create the four main categories you’ll find on TONE3000: Standard, Lite, Feather, and Nano.

Each format uses a different amount of processing power. The tradeoff is simple: bigger models give more realism and dynamic accuracy, while smaller ones are faster and easier to run on modest hardware like slower computers and portable effects units for live performance.

TONE3000 offers all formats of NAM captures

Standard NAM

The Standard version is the highest-fidelity model available. It captures every nuance of the amp’s frequency response, harmonic structure, and pick sensitivity. Because it uses the full neural network resolution, it demands the most from your CPU, but the payoff is tone and feel that’s almost indistinguishable from the real thing.

Standard models are best for recording, re-amping, and critical listening environments where tonal precision matters most.

Lite NAM

Lite models are reduced versions of the Standard capture. They keep most of the dynamic character intact but simplify the internal structure of the model to make it easier to run.

These are ideal when you’re stacking multiple amps in a mix, building complex live rigs, or working on a laptop where system resources are limited. For most players, the sonic difference is nearly impossible to notice in a live mix.

Feather NAM

Feather models were designed for players who need ultra-low latency and smooth real-time response. They sit between Nano and Light in terms of tone accuracy but are optimized for real-time playing and minimal system load.

They’re especially popular for live use and portable setups that rely on fast, responsive tones without straining your computer or hardware NAM player.

Nano NAM

Nano is the smallest and most lightweight format. These models use aggressive compression and pruning to shrink the neural network down to a fraction of its original size.

You’ll lose some subtlety in transient response and low-end dynamics, but Nano NAM captures still sound great, especially through a live mix or portable hardware device. They’re perfect for mobile rigs, budget systems, or low-power hardware NAM players such as the Valeton GP series and other NAM-compatible pedals. Many hardware units currently on the market use Nano NAM captures exclusively.

Choosing the Right Version

If you’re unsure which one to use, here are a few rules of thumb you can follow. For working in the studio (or bedroom studio), start with the Standard version. If it doesn’t cause any issues with latency on your computer, you know you’re getting the best possible experience and tone. If there is some audible lag between your playing and the response you’re getting out of your monitors or headphones, work your way down through the other versions until you don’t hear it anymore. Finally, if you’re using a NAM-compatible hardware player, just make sure you’re using whichever NAM format it requires, but understand that you’ll likely get the best playing performance out of a Nano NAM file.

Here’s a quick comparison chart:

The Takeaway

Since every NAM file on TONE3000 originates from the same amp, pedal, or outboard gear capture, you’re always starting with a legit, authentic tone. The main difference is how efficiently that tone runs on your system, and how well it’s reproduced. If you have golden ears, a well-tuned studio environment, and professional monitors, you’ll likely hear some difference between the formats. If you’re rocking out on stage or in a practice space, it’s unlikely you’ll ever notice any difference in audio quality, although you may notice a difference in latency.

From studio-grade precision to onstage convenience, each of these formats serves their own purpose. Together, they make NAM one of the most flexible tone technologies ever created.
