Positive Grid Spark MINI 10W Small Smart Guitar Amp & Bluetooth Speaker | Portable Sound for Guitar Playing at Home or On The Go | Pearl

Despite its small size, it delivers rich, full sound with impressive clarity and punch — perfect for bedroom jams, travel setups, or impromptu sessions anywhere. One of its biggest advantages over other small amps is the built-in rechargeable battery. No need to hunt for outlets or swap AA batteries — just charge it via USB-C and you're good to go for hours. This makes it genuinely portable in a way most practice amps just aren’t. The Spark app unlocks a massive sound library with thousands of tones, artist presets, and genre-specific setups. Whether you're chasing vintage blues, modern metal, or ambient textures, there’s a preset ready to inspire. Plus, you can tweak and save your own tones with ease.

Before I bought this, I watched nearly countless review videos to build a general opinion. When I bought and received this product, I got to admit I am very impressed. It's easy to use and packed with MANY features that can be used in a multitude of ways with a bit of creativity. Given the small size and built in battery, it doesn't generate much power drain if energy usage is your thing. It can become very loud and very quiet. There's also a 3.5mm headphone jack in case you don't want to blare the speakers, perfect for exploring the sounds and how to adapt them to your skill level. I personally like the fact that I don't need to lug around a bunch of cables and pedals to generate a neat effect on the guitar. There is a wireless pedal that compliments this product, which I will be investing in later down the road. I DID run into one MAJOR PROBLEM, though. And I feel the need to echo it and my findings here: I had been experiencing the Spark app crashing on my phone after a few minutes of playing with it. It really killed my experience and I nearly formed a poor opinion about the PositiveGrid group. I am happy to report that this experience is a unique issue that happens on "high end" phones that have a refresh rate above 60fps (e.g., if you have a 120 Hz "smooth display"). Apparently the devs of the app didn't consider that their app would run above 60fps, which causes the app to crash. While PositiveGrid [hopefully] works on this, the best workaround is to enable "power saving mode" on your phone, which would likely lock your phones refresh rate at 60fps, allowing a crash-free experience. After learning this, I haven't had a single issue with my experience with this product and it's proprietary app. This is a great product if you enjoy guitar playing or if you know someone who likes to play the guitar but YOU, yourself, know little about guitars.

I resisted the spark in favor of my Katana Mini for a long time. My main problem is: I want to just plug in my guitar and start shredding and not spend a ton of time on an app. But the main problem with the Kata is: no rechargeable battery (remembering to charge AAs is a pain!). I needed a bluetooth speaker anyway, so I decided to give the Spark Mini a try. First off: it's louder than the Katana Mini. Both the Spark and Katana can get louder than I would ever want from a mini practice amp (and both of them start to sound a little funky if you really crank 'em). The Spark has more bass which, again, is not surprising being as how it has 2 speakers and acts as a BT speaker as well. Tone-wise: man they are both good. The Katana has its' own sound, whereas the Spark is trying to sound like other amps. Pound for pound, I think the Katana has a more interesting/unique tone but the Spark more than makes up for it with versatility. Controls are really easy to use. You can save patches over the hardware slots and then never connect to the Spark with your phone again if you want to. That's a key piece for me because, again, I just want software that feels more like a real amp / hardware. This really does a good job of that. And I found myself having more fun with the app than I thought I would (for example, the "jam along" tracks are actually really fun!). I like the simplicity of the controls too. I don't ever want to be in an amp modeler and choosing between an SM57 or a different mic and placing it in a virtual space next to the speaker cone. That stuff doesn't ACTUALLY sound like placing real mics anyway, and it's everything I dislike about modelers. I just want simple controls that sound good (which is why the Neural DSP have been the only plugins I have used long-term on my PC). You can choose a gate, comp/wah, drive/fuzz, amp/cab, mod/eq, delay, and reverb. They all are easy to use and sound good. As a bluetooth speaker: man this thing sounds GREAT for music. It's a bit high in price if you're just buying it as a speaker, but the fact that it does double duty makes it a no-brainer if you're a guitar player. I've honestly used it as a BT speaker about as much as I've used it for guitar. It's so good. Overall, this is something I would buy again. If you're looking for a great practice amp and a bluetooth speaker, this is an awesome choice!

This thing is very light, and very small; I would have preferred a little bulkier. You can also use it as a Bluetooth speaker; right out of the box you can pair it with your cell phone, no special setup required Now as a mini amp, this is where it surprises. Is as if you do not only purchase an amp with good sound, but some effect pedals. You need to download an app (you do not need the app to use it, but it comes with a delay that you need to tune down if you want to use it as an amp, unless your style requires a high delay all the time). The app will show you pictures of pedals, with all the knobs and settings you would find in a real pedal. You move the knobs on the picture to set up the effect. The effects will not work while in Bluetooth speaker mode, and they sound like real pedals, not just toy effects really good sound and good effects

So far, so good…works as per specifications.

C'est réellement étonnant! Je l'ai acheté pour ne pas avoir à allumer mon Marshall tout lampes qui chauffe la pièce, et c'est la meilleure chose que j'ai faite depuis longtemps en matière d'achat musique! Le son est puissant pour la taille, et les possibilités sont infinies avec l'app associée. La configuration est rapide et facile, en quelques minutes, vous êtes prêts! Les sont sont variés et très bien reproduits. Que ce soit avec une acoustique ou une électrique, c'est vraiment bon. On sent bien que les progrès de modélisation sonore ont été importants depuis quelques années. Comme ampli de chambre/bureau pour s'entrainer, c'est parfait! Il est très compact, esthétique et pratique. Couplé à un transmetteur sans fil pour guitare, c'est idéal. L'application dédiée permet tous les réglages imaginables pour tous les styles. Elle est bien faite, à part la partie qui crée de l'accompagnement en fonction des accords joués, soit disant grâce à l'IA, qui est décidémment partout, qui fait de la bouillie, tout le reste est pratique. Choix du modèle d'ampli, des pédales d'effet actives et des paramètres avec les boutons virtuels, comme sur les vrais. Une fois le son trouvé, vous pouvez le sauvegarder dans une des 4 mémoires dédiées sur le premier bouton en remplaçant les sons d'origine. Bref, beaucoup de choses à explorer avec ce petit ampli de chez Positive Grid, et pour le prix, vous ne serez pas déçus, c'est sûr!

This little amp is nothing short of astounding! When I first got it I wasn't particularly impressed with the preset sounds and then I started fiddling about on the app. There are lots of different amps and effects to choose from and you can get a whole range of tones. It won't take you long to find 'YOUR' sounds. Save them to the presets and away you go! I don't know how Positive Grid do it, but you get this immense sound coming out of this tiny box. If you like Dave Gilmour and have the 'Delicate Sounds of Thunder' live album, you can actually get something very close to that immense sound he creates. The app is just brilliant! You have all these backing tracks from fusion, to soul, to rock, that you can jam along with and the sound of your guitar will be synced with the track perfectly. I've tried doing the same thing with my Katana and it wasn't as good. They just don't sound as synced. I hardly ever play my big amps any more as the mini pretty much does anything I need. If you're toying about with the idea of getting one of these ask yourself, 'What volume do I play at most of the time?' I play at home and don't need big volumes, in fact I rarely put my other amps above 2. Also because it's battery powered you can take it anywhere, which I can't do with my little Blackstar Fly. The Mini is really well made and sits nicely in any space. There are a lot of other useful features on the app like showing you the chords you're playing in real time and I think it makes you more aware of how you play. I've been playing for nearly 40 years and I don't think I've ever enjoyed playing an amp as much as this. One thing I would note however, is that if you're playing a single coil guitar and you have the noise gate on, it will choke out the higher notes particularly on the high E string. You won't get this as bad with humbuckers. Just turn the noise gate off and this will help. For the money you pay, you get A LOT and I really mean that. There are quite a few reviewers on YouTube who actually prefer the Mini over the bigger Spark 40. Treat yourself to one, I don't think you'll regret it!

I pre-ordered the Spark Mini and it arrived 11 days before I expected. Setup was easy, I upgraded the firmware to the latest version and it was ready to go. Despite of having fewer knobs that its big brother, the app makes it very easy to configure a rig like the big one I have. I got the tones I like quickly and assigned to the presets knob. It sounds very good, much better than another portable (but bigger) amp I have, plus the Mini works as a bluetooth speaker. Battery last a lot, in fact I have charged once a week with one hour of playing daily. It looks very good and finish is high quality. It's pricey but it packs a lot of technology. In other countries, those who pre-ordered it got the red grid as well, not our case in Australia, hence the missing star in value for money.

Mycket schysst och smidig stärkare i kompakt format!
