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

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!

I was originally opposed to this amp since it didn't seem like a "real" amp to me, but man is this thing fun. You can dial in tons of different but great tones. I was also concerned it wouldn't get loud enough but when I'm in my house right around 50% on the volume dial is perfect for practicing. That's still loud enough that the kids can't hear the TV over it. The battery lasts a long time and it is just so convenient to take it to whatever room you want to practice in. My daughter takes it to her guitar lessons and we can flip tones around easily to match whatever song she is going through with her instructor. It is a lot of fun to experiment with different combinations of modeled amps and pedals and play with the settings, although it can be overwhelming trying to find something that sounds great. It is pretty easy to search the "tone cloud" though and try out other people's settings. Great little amp and absolutely perfect for at home use or lessons.

A lot of sound out of a compact package - huge volume and sound quality improvement over the Spark Go! A lot of tones and customization via the Phone app; by only 4 HW presets. For the most part pretty reliable; I've had to factory reset it only once to restore Bluetooth/Phone connectivity. About my only real disappointment is the quality of the tone library via the app. Yes, there's a whole lot of selectable amp/effect tones you can choose from; but most of them are not sounds you're gonna want. The adjustments (effects, different amps, different settings) allow for a lot of customization but the app screen controls to adjust settings can be pretty frustrating. I'd have to say the amp itself is nice; but the app is a bit of a let down and a bit buggy at that.

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

Solid well designed and built little amp. The form factor is great. It can go anywhere and produces a big sound with a battery that lasts a long time. Once I went through the long process of configuring presets for optimal sound with my instruments (acoustic guitar and dulcimer: both with pickups) the sound was good, natural and as loud as needed. I also updated the firmware which was a bit of a pain. The jam feature seems gimmicky though I haven't played with it much. Overall, the presets, quality of effects etc are pretty good. As a bluetooth speaker it's okay. The sound is reasonably balanced though it lacks true fidelity e.g. good sound stage, crisp clean high etc. I suspect part of the reason is a cheap SBC bluetooth audio codec. Codecs can make a huge difference. The should have at least used Apt-X which would produce better sound. Overall, it's a piece of quality gear for those who want a solid practice amp in a tiny go anywhere form factor. As a bluetooth speaker it does fine but don't expect high fidelity. EDIT: changed rating from 4 to five stars. Bluetooth audio now sounds great. The problem was not the Spark mini but rather a codec issue. If you're playing audio from a late model, Android phone. (I have a pixel 6)) then you need to go into your settings and turn on "disable Bluetooth A2DP hardware offload". You can Google how to do this. It's not that difficult. Once done, you will get crisp clear audio on the spark mini and on any other Bluetooth devices that use the SBC codec.

Fantastic amp. Now I have all of them, the mini, the go and the 40w. I also have the wireless links. I'm all in with Positive Grid because of their high quality, reasonable price and great looks and performance. Their tone cloud and other features are top notch as well. Great product. My only wish is that they would come out with a travel case for it. The go and the 40w both have cases.
