What is it?

The Line 6 Helix hardware was a pretty big deal when it initially launched back in 2015. It made professional-grade modeling tones available to the masses, spawning a number of off-shoots including the HX Stomp, HX Effects, HX One and more. It was only natural that a plugin version was on the cards. Cue Helix Native in 2017 – a plugin that boasted all of the same tones that made the Helix such a hit. Things have since moved on, with the recent release of the Helix Stadium XL hardware featuring Line 6’s revamped Agoura amp modeling, and this year has seen the plugin catch up with Helix Stadium Native.

The deal remains the same in that we are getting tones identical to the hardware, but in plugin form, and Line 6 has also created a free Helix Stadium Intro version for you to try. As a regular user of Helix Native and having previously reviewed the Helix Stadium XL hardware, it is fair to say that I am expecting a lot here.

The main news and the biggest upgrade from the previous version of Native is the Agoura amp models. Named after the area of Calabasas, California, where Line 6 is headquartered, these models are more than just an updated version of their HX predecessors – they are an entirely new way of doing things.

They use sub-component behavior modeling to accurately recreate a digital model of real-world amplifiers, and feature communication between the amp and cab blocks that reflects the interaction between the two things in real life.

The Agoura models react much more as an amp would

Native is particularly adept at showing the difference between the two versions as it hosts both the new Agoura models and the older HX versions, so I load up the US Double Black Agoura model on its Vibrato channel and compare it to the US Double Vib legacy model.

Tonally, they are relatively similar, both reflecting the scooped sound of a Fender Twin Reverb, with the Agoura model being noticeably smoother in the high end and free from the spikiness of the legacy model.

Boosting with the Screamer 808 is where the difference really stands out. The Screamer sounds rather thin and unpleasant through the legacy model, but fat and smooth through the Agoura. In short, the Agoura reacts much more like an amp would with a Tube Screamer-type stompbox in front of it.

To Line 6’s credit, the company regularly brought meaningful updates to the Helix firmware, so these differences are less pronounced when using the more recent HX models. For example, the Panama Red (EVH 5150 III), which was added in 2024, is much closer in quality to the new Agoura version. In fact, I find myself preferring the smoother mid-range of the HX model.

Aside from this outlier, the Agoura models have the edge, with subtle improvements in dynamic response pervading. All in all, they just feel a little more alive under the fingers.

A welcome new addition to the Agoura models is the Hype control. It takes the focus away from direct clones of real-world models and moves towards creating idealized versions of these amplifiers.

It’s a sliding scale, meaning the more of the Hype Control that you dial in, the closer to the ideal (or what Line 6 has deemed as ideal) version the tone gets.

This is somewhat objective, and for me is a bit hit or miss. For example, I like the liveliness Hype brings to the Princess 76 (Princeton) model, but dislike how it lessens the trademark mid-scoop of the Double Black (Fender Twin) model.

Overall, I feel this is a positive step for digital amplification. Forward-thinking amp brands are always trying to refine and improve their sounds, and one of the benefits of modeling amps is that they can do this without the restraints of physical hardware. The Hype control is a good way to make use of this.

Line 6’s fully original digital models like the Litigator have been well received in the past; therefore, it seems to me that digital guitar tone has real potential to move away from direct clones of real amps into high-end original tones, without the physical restrictions of using actual parts.

Having noted Line 6’s form for bringing meaningful updates, there are already three new amplifiers to check out from the 1.2 Stadium update: US Super Black, Kali 2 C+, and Brit Jujubi.

I find myself particularly enjoying the Brit Jujubi, and it quickly becomes my favourite Marshall in Native due to the slightly warmer take on the JCM800 sound.

The Super Black requires a bit of work, as the high end can be brittle, but it yields a rewarding clean once some time is spent here. I also find the Hype control helpful for bringing the high end into a place where it adds some life without sounding shrill.

The opposite is true of the Kali 2 C+, which boasts an addictive, heavily saturated Mesa drive with hardly any tweaking. Sticking on a backing track, I spend what is probably a little too much time shredding away on this endlessly fun tone.

Both the Jujubi and the Kali 2 C+ make use of the Agoura model’s ability to host multiple amp channels within the same model, particularly the Jujubi, which boasts four channels running the gamut from clean to all-out saturation.

Getting started with the Proxy Clones, I download a Soldano SLO 100 and a Dumble amp and cab Clone, plus a Fender Princeton amp-only clone and find the results to be mixed. The Soldano provides a soaring drive perfect for heavy rhythms with a ton of high-end presence. Stick the Screamer 808 model in front of it, and the high end is tamed, the midrange is pushed forward slightly, and that drive tips into saturation, leading to a perfect, 80’s-inspired lead tone.

The Dumble, however, is thin with an ugly hiss, and the Princeton is a little bit muddy until I back off the pre-gain, at which point it turns into a lovely, glassy Fender clean. So, as with all iterations of capture-based technology, the results very much depend on the quality of the capture.

Still relatively early on in Proxy’s life, there are not many sounds to choose from compared to more established offerings from the likes of Kemper and Tonex. As things stand, and particularly considering there is no rating system to discern the good from the bad, I would opt to use Native’s digital models over the Proxy clones, but there is certainly some potential here.

When it comes to digital effects, Line 6 has rightfully been on the receiving end of praise from users and ourselves, so it adopted the ‘if it ain’t broke, don’t fix it’ approach and directly ported the HX effects into the Stadium hardware, and now Stadium Native.

We’ve covered these effects extensively in products like the Helix Floor, HX Effects, and HX One, to name just a few in the ever-growing Helix family. Highlights for me include the Hot Springs reverb, which accurately recreates the drip of a spring reverb, with a vast array of options that will suit any obsessive tweaker.

Also, the simple but effective Transient Delay, which is a Line 6 original that impressively mimics the way an analog delay darkens on repeats. And the PlastiChorus, another Line 6 Original that adds some pleasing wobble whilst not overshadowing the transient of your pick attack.

There are a few effects I am not a fan of. The pitch effects sound a little thin, with the exception of the Pitch Wham, which does retain a sound with plenty of girth. Also, there is a little warble introduced in effects like the Poly Capo. Still useful in a pinch if you’re recording for a singer who changes key on you at the last minute, but certainly not a go-to for this.

The drives offer a huge amount of variety

The drives offer a huge amount of variety, ranging from subtle boosts to all-out distortion and various flavours of fuzz pedals. Some, like the Prize Drive, are convincing replicas of the real-life units they are based on, while others like the Arbiter Fuzz are a load of fun in their own right, but differ from the originals they are copying. In this case, the model is more ‘spitty’ than a real Fuzz Face.

I find myself enjoying the mid-hump of the Screamer 808 to boost amps like the aforementioned Brit Jujubi, and the Teemah! for a versatile, relatively high-gain drive on a clean amp.

Verdict

$399 is a lot of money for a plugin. However, this is vastly capable plugin. From squeaky clean Fender-inspired sounds to over-the-top metal distortion and outlandish synth, it leaves no stone unturned in the land of guitar tone.

And of course, I would be remiss not to mention that users of the Helix Stadium hardware and the previous version of Helix Native can pick up the plugin at a hugely reduced price of $99. POD farm users also benefit from a discounted price – $299 for standard users, $199 for Platinum users.

At $399, however, there is very little room for error. A UI that does not scale properly on certain monitors when using Windows machines is a big misstep, and extra disappointing considering this is not a new issue.

At $399, however, there is very little room for error.

Also, with brands like IK Multimedia able to create captures through its Tonex desktop software, some may be disappointed by the lack of the ability to create Proxy Clones with Stadium Native.

This, combined with the different prices, creates two separate propositions. At $99, Native is a no-brainer. At $399, you might want to consider how much of a drawback these criticisms are and how much you will use the wide array of tones available here.

It is worth bearing in mind too that Line 6 has also released Helix Stadium Native Intro. A massively cut-down version of the plugin that is completely free.

What is undeniable, however, is that if you are someone who is regularly recording music of varying styles, Helix Stadium Native will be hard to beat as a one-stop shop for everything guitar.

Guitar World verdict: While things like the scaling issue on some Windows monitors and the lack of ability to run as a standalone app may put a few people off at the full $399 price, it is no exaggeration to say that Stadium Native can cover every style of music. When it comes to guitar sounds, it is a truly complete suite of professional-grade tones and may be the only guitar plugin you will ever need.
