How to Choose the Best Modelling Guitar Combos
1
Tone Modelling
Positive Grid's BIAS engine is the core. It's genuinely impressive how they've captured the nuances of iconic amps and cabs, but it's not always a perfect recreation - sometimes it's a better version, with more headroom or a more controllable breakup. The ability to tweak parameters and create custom amp models is a huge draw.
2
Speaker Simulation
This is where a lot of modelling amps stumble, but Positive Grid's IR (Impulse Response) library is surprisingly strong. You get a decent range of cab tones built-in, and the option to load your own IRs takes it to another level - crucial for getting a truly authentic recorded tone. The Spark's auto-generated backing tracks are a neat trick, but don't expect them to replace a real band.
3
User Interface & Software
The BIAS Tone Cloud is a mixed bag. The sheer number of user-created amp and effect presets can be overwhelming, but it also means you'll likely find something that works for you. The app itself is generally intuitive, but occasional glitches and connectivity issues are a reality.
4
Build Quality
This is a consistent point of critique. The plastic enclosures on some models (like the Spark) feel a little cheap for the price. The HZ series steps up the build quality significantly, but you pay for it. It's a trade-off - you're getting advanced modelling in a lighter, more portable package, but that comes at the expense of premium materials.
5
Dynamic Response & Articulation
This is where Positive Grid really shines. The BIAS engine does a fantastic job of responding to your picking dynamics, giving you a surprising amount of nuance and feel, especially when compared to older modelling amps. It's the difference between a sterile, lifeless sound and something that actually breathes.
Buying Guide
Positive Grid amps are great for bedroom practice, recording, and even gigging, but be realistic about what you're getting. The Spark is a fantastic entry point, but don't expect high-end studio tone. If you're serious about recording, invest in a good set of headphones or monitors - the onboard speakers are... adequate. The HZ series is a serious contender for gigging, but budget accordingly.
Our Methodology
We're not just looking at spec sheets here. We've spent serious time with these amps - plugging them into various guitars, running them through different recording interfaces, and most importantly, gigging with them. A/B comparisons against both classic amps and other modelling solutions are key, because the devil's in the details, especially when it comes to how an amp responds to dynamics.
Frequently Asked Questions
'As good' is subjective. They capture the essence of many classic amps, and often improve on them with more flexibility and control. But the subtle imperfections and mojo of a vintage amp are hard to replicate perfectly.
Absolutely! Most models support loading custom IRs, which is essential for dialing in a truly authentic cab tone. Just make sure the amp supports the IR format you're using.
The Spark is the budget-friendly, all-in-one practice amp with smart features. The HZ series focuses on high-end tone and build quality. BIAS is the software engine and hardware platform that allows for deep customization and amp modelling.
It depends. The Tone Cloud offers tons of presets, so you can get something decent right out of the box. But the real power comes from digging into the BIAS engine and customizing your own sounds.
Generally, yes. The presets are easy to switch between, and the effects are well-integrated. However, the app-based editing can be a bit clunky if you're trying to make changes on the fly.
