Ad feature with Positive Grid

If you’re a guitar player, there’s a very good chance that on more than one occasion you’ll have found yourself stumped trying to think of a guitar sound that is authentically yours. Despite the huge gamut of guitars, amps and effects available for us to play with here in 2026, sometimes the sheer wealth of choice can be overwhelming, and as such we end up leaning on accepted gear combinations and tried and true solutions.

Most of the time that’s fine, but sometimes you just want to push yourself out of your comfort zone, right? It’s no fun ploughing the same furrow forever, and unless you’re very lucky, it’s unlikely that such an approach is going to help you develop a sound or guitar style that’s truly your own.

Positive Grid has been trying to help guitarists get over this hump in a variety of ways over the last few years. First, they built an AI helper into their impressive Spark 2 practice amp that could help you find your sound with just a few words, then they built a more powerful and advanced version into the Bias X software that helped make in-the-box guitar playing less intimidating for newbies. Now however, they’re taking things to the next level.

REACTOR is PG’s brand new gig-ready amp aimed at those who want to sound good without breaking the bank. While it has all the usual impressive features and onboard sounds you’d expect from a Positive Grid amp, the most intriguing feature might be Amp Intelligence.

Amp Intelligence is, essentially, a guitar-centric intelligent tone engine designed to help you take the sound that’s in your head and make it a reality. Using the companion REACTOR smartphone app, you can interact with it in a variety of ways: whether it’s via a text-based prompt, an image or a sound sample. You can simply hand it over to Amp Intelligence and in no time at all, it’ll fire out a bunch of presets for you to audition on the amp in real time.

The useful potential of this is pretty clear from just a few minutes of using it. For starters, it’s pretty dang good at recognising a played guitar tone and reproducing it. We threw an old band demo recording into Amp Intelligence with very little clue what exactly had been used to record the original, and within a minute or two it had presented three very usable, very decent sonic approximations of what it heard. It also can do that trick with instruments, too – if you show it a picture of a certain type of guitar, it’ll pull out some classic tonal pairings to go with them, and they’re very impressive.

The amp can also act as a really interesting creative tool, creating tones based on pretty much anything that can be typed, photographers or captured via audio.

With something as broad and powerful as Amp Intelligence, there’s also the potential to get rather silly, and well… that’s where we’re going today. Let’s take the most leftfield nonsense we can come up with and see how Amp Intelligence handles the task. It’s time to get weird.

Cat’s Entertainment

The logical place to start, if we’re really going to try and get weird, is to pick something that really has got absolutely nothing to do with music and see what happens. It’s convenient then, that a rather handsome and entirely unknown interloper of the feline variety decides to wander through an ajar kitchen door and into the house just as we’re mulling over exactly what kind of flora or fauna to choose.

A quick photo of this incredibly majestic creature is duly snapped wandering around the kitchen like he owns the place – how will REACTOR’s Amp Intelligence handle a picture of a cat?

Well, pretty amusingly well actually. “You wanted a ‘pur-fect’ jazz’ tone inspired by a playful Balinese or Siamese cat,” it responds, before handing me a bunch of warm, soft and smooth jazzy tones with names like “Playful Jazz Cat” – they all sound good, especially when I start pulling out the ninth chords and switch on my Jazzmaster’s rhythm circuit.

Interestingly, when I put the same prompt in a second time it offered me something completely different – this time offering me ‘Meow-y’ wah-based sounds instead – showing the potential for Amp Intelligence to offer so many unique options no matter what you ask it – and of course you can then tweak these tones to taste in the apps conventional tone editor.

Orange You Glad I Called?

Right, we’ve done animals, it’s time to take something even weirder – food. We did contemplate giving Amp Intelligence a delicious burger or even a perfectly stuffed gyros to work with, but quite frankly nobody should have such things to hand in the middle of a working day, and so we had to work with what was at hand instead… Hmm, what about the fruit bowl?

I half wish I’d made the oranges a little more prominent in the photo in the hope that it would really go route one, but instead the image of fruit sent Amp Intelligence to sunny climbs and tropical paradises, offering me a “fruity bossa” tone in various flavours.

Of these, the mellow, mid-boosted Apple Jazz was very fun for more of those comped chords, while Tropical Fruit Clean gave a strident but enjoyable fruit punch (sorry) to proceedings.

Chapter and Verse

Okay, it’s done a pretty impressive job with the first two weird things, but let’s push things really outside the box. We wanted to give the Amp Intelligence something truly odd – like say, this writer reciting William Blake’s seminal 1794 poem The Tyger?

Now Positive Grid is pretty clear that this function is designed for you to play actual music into in order to generate the tone. We don’t expect that they ever expected Amp Intelligence to have to make a tone present based on someone theatrically reciting an early-Romantic verse on the duality of beauty and ferocity in their spare bedroom.

So despite not missing a beat in terms of actually crafting the sounds, the created presets don’t exactly feel hugely grounded in the subject matter. Perhaps the amp’s generation of four “sledgehammer high-output lead” tones speaks to the potent metaphor of the tyger, burning bright in the forest of the night? It’s pretty metal, you have to say. Either way, all the tones sounded good, even if they were working with some suitably unhelpful subject matter.

Real World Benefits

Over the course of our little experiment, it has become abundantly clear that not only can Amp Intelligence handle the weirdest stuff you can throw at and turn that into some surprisingly usable and logical guitar tones. If you’re really struggling to find a new sound for a song, or just feeling creatively underwhelmed, there’s an element of Brian Eno’s legendary Oblique Strategies to chucking random objects at Amp Intelligence and seeing what it spits out.

What’s more, it’s worth remembering that the REACTOR is an amp priced in the realms of beginners who are moving into playing live and taking the instrument seriously. It’s so easy to imagine Amp Intelligence helping them discover how different amps and effects work together by creating presets that they can then edit and dig into – without having to build from the ground up. It can even create wholly original amps using its component-level modelling and understanding of hundreds of classic circuits. The sky’s the limit.

Maybe you’ve never thought about whether you might need an amp that you can have a conversation with before, but Amp Intelligence and the Positive Grid REACTOR makes a case that you should start asking questions…

D’Addario has unveiled a new line of “climate-smart” guitar cases designed to keep the environment around your guitar stable, even when on the move.

Aimed at guitarists and bassists taking their instrument on the move – to rehearsals, gigs, and sessions, for example – D’Addario’s new Backline Electric Guitar and Bass Cases feature a host of storage compartments in a streamlined gig-bag-style design, but the USP has to be the Humidpak Climate-Control Neck Cradle.

Humidity can have a big effect on the way your guitar plays. The porous wood that makes up the instrument naturally expands and contracts in varying humidity levels, leading to playability and tuning issues if not kept stable. The Humidpak Climate-Control Neck Cradle features a two-way humidity control to keep humidity – and your instrument – stable.

The Backline cases – made of water-resistant materials and reinforced construction with shock-absorbent padding – also feature a detachable Breakaway Bag with Auto Lock security to keep accessories organised and moveable to and from the stage.

They also sport balanced ergonomic straps as well as a cushioned back panel to ensure maximum comfort while in transit.

D’Addario’s new Backline cases are “premium transport solutions designed to deliver superior instrument protection, user comfort and accessory organisation, all without the bulk of a traditional hard case”.

While no concrete information is available yet, D’Addario says an acoustic guitar version “is expected to follow”.
