    • Husband absolutely loves it!
Color: Black
I purchased the Positive Grid Spark for my husband, and it has been one of the best gifts I’ve ever given him. The sound quality is incredible, and he loves having access to so many amp tones and effects through the app. The setup was simple, and the app makes it easy to customize sounds and play along with his favorite music. It’s compact enough for home use but powerful enough to fill the room with great sound. He uses it all the time and can’t stop talking about how much he enjoys it. Highly recommended for any guitar player! ... show more

    • Very cool little amp!
Color: Black
Review Image by Chad L.
I really 100% wish this had been available back when I started playing -- it would be a great way for beginners (young or old) to get started playing guitar -- perfect for that! The apps make it easy to choose a custom amp/rig sound, or to search for other players' recommendations on which rigs can help you get certain sounds (i.e. like how to make your rig sound like certain songs from bands like Deftones vs the tones/sounds from various songs by Alice in Chains, or Foo Fighters, etc. ) Here's what I love about it: The amp is also great because of the onboard controls and ability to shape sound -- even if you didn't use the app at all! It has great sound (at 40 watts not LOUD loud but absolutely fine for beginners and/or as a spare practice amp for others (how I plan to use it myself.) It has a switch with 7 different core amp modeling sounds (Acoustic, Bass, Clean, Glassy, Crunch, Hi-Gain, Metal.) This is awesome because you can simply plug in your guitar and start playing with that huge range of tones and sounds -- so you don't need to go buying effects pedals out right out of the gate (TONS of sound shaping options here for the price, and being built right into the amp.) In addition - you also have built in Delay, Reverb and Modulation --- that's three more effects you get to experiment with but not have to buy separate pedals as you get started! They have some cool ideas going with the way it can bring in a 'virtual drummer' or bassist to accompany what you're playing - how cool is that!? (It's not perfect, but what in life is? In this case -- it's all software (in the app) so they can upgrade/enhance it over time -- which is the absolute miracle about living in this age of tech. So like with other gear out there - this product and experience could get better and better, it all depends on how the company supports it over time --- but their website and customer forums/support section seem very solid and active -- my gut says this product will keep getting better...) For me, since I've been playing for years (too many to admit) and have accumulated lots of amps and effects -- I mainly bought this amp for the amp modeling functionality through the app, and to see what the 'virtual drummer' and bassist would be like... if I remember back to my 'beginner' days this amp with the app functionality would have been PERFECT... (and I'm looking forward to seeing how this company supports/enhances the functionality of the app - I've been impressed so far so I'm optimistic!) If all that wasn't enough -- it can also be used as a bluetooth device or powered speaker also! For this price -- it does a whole lot in such a small package -- perfect for beginners, but also useful and well worth the small price for 'veterans' like myself who always have a way to use an extra little practice amp! ... show more

    • Sounds stunning through headphones and the USB out
Color: Black
I am not going to talk about the features of this amp, they are numerous and well thought out. I will say The included drum machine is a welcome feature for new players instead of a metronome. This will get you up and rocking a lot faster. If you are not comfortable controlling this with a smartphone or computer, then I would look elsewhere. If you are fine with this, then this can be the best-sounding practice amp under 300$, by a mile. My only complaint with this amp is it needs an additional Digital signal processor between the effects loop and the actual power amp, the speakers without correction are very dark and boomy.. There are 3 models of the spark amps and they all share the same tone cloud, so this thing sounds best when recording, or using the headphone out. In the spark 40, the speakers sound a bit dark, where they sound lean on the smaller units. But do not fret(pun intended) You can add an overdrive module on the front end of the chain and use the tone knob on that to boost the upper mids. There is also a 7 band EQ, and if you bring down 200 and 500hz, then lift 2k and 4k a touch, you can get a nice, rock/metal tone that sounds utterly fantastic through the speakers. I would not have believed it if I did not hear it for myself, this thing is stunning once you compensate for the speakers.. Just note that if you use the EQ, you will not be able to add modulation effects. Also note that the tones you create for the speakers will sound lean and harsh through headphones or recording through the USB out. Fortunately, you can store them in your phone, or have up tp 4 stored on the unit to switch between tones for recording, and tones for playing through the speakers. This is the best-sounding practice amp I have ever used. It is easy to dial in tones, and once you EQ the speakers, this thing sounds amazing. It can get loud enough to rock out in a living room without annoying your neighbors, but not loud enough to play over a drum kit. You could gig at a coffee bar or small acoustic venue, but that would be it. Regardles,s it gets surprisingly loud for its size, and sounds like a much bigger amp. I am impressed. ... show more

    • An outstanding little amp
Color: Black
I was not prepared to like this amp as much as I do. Having used it for about a week or so, I am very impressed with the quality and performance. I don't care for the "brick" power supply, but it is not enough of an issue to lose any stars. It also offers some options if the power supply goes out, so pros and cons there. It is loud. Louder than it has a right to be. I cannot believe how much sound it puts out in such a small package, and I have been using amps and speakers for nearly 60 years, including more than 24 years in the professional audiovisual field. I am quite impressed, and I don't say that lightly. I know some people complain about it being "too bass heavy," but I find that kind of a silly complaint. Of course, I don't like bright, twangy, banjo like-guitars sounds (read Fender), so there you go. I prefer a more balanced sound with a good strong low end (most of the time, anyway). Using the various EQs available, I can get more high end than I like, so I am fine with how it sounds. Since it is also usable for bass, you need the lower end. Perhaps a bass cut switch would help here. I would like to see the graphic EQ moved to a different set of effects, maybe have a dedicated set of EQs like they do other effects. I think they have way too many distortion effects, but then I like to hear more actual guitar sounds than a load of grating noise. A lot of over the top metal sounds are just pure noise to me, and I think people sometimes use the noise to cover up poor technique. (I know I have . . . .) If you want grating square wave noisey signals, get a synth. They do it better and in a more musical way. My two cents . . . . The amp has very nice clean sounds, and very usable tube crunch sounds. One can spend a great deal of time just exploring all the sounds available with the various effects, which I intend to do. I was surprised how easy the app was to use. I am not a fan of using apps to control everything, but I can see the advantage in this case. I was not surprised to find out that a lot of the marketed "features" of the amp are actually cloud/network functions you need to be connected to the internet to use. Again, not a bad compromise in this price range, although they should clarify that in their advertising. It does still function quite well as just a hardware amp with knob controls, and is still a bargain just using it that way. As many people suggest, you can use the app to set up the four presets, and just use it that way. I would like to see more presets, maybe six or eight, but even with just two it would still be a great amp. I have not signed into their website, which you have to do to access all the cloud based functions, but will probably do that eventually. They have also come out with an expansion cabinet with 140 watts of power, making it a real gigging amp for a lot of venues. I debated giving the fifth star or not, as I would like to see a real line out (balanced, even) and not just a headphone out, although it can sort of function as a line out. I think not having a dedicated line out whch does not cut the speakers would be far more functional and make this amp more like 6 or 7 stars, especially if they move the EQ in the effect chain. I find it to be a great little amp and I very much recommend giving it serious thought. Paired with an Eart headless guitar, it makes a very compact setup with some serious growth potential (and parents take note, it does have a headphone jack!). It is also great for players with very little space for gear (nomads and such). Well worth a look if you are in the market for an amp. ... show more

    • So Far, So Amazing
Color: Black
Review Image by Coach305
UPDATE (May 28, 2021): Finally got my Galaxy Tab A7 and had no problem pairing it with the Spark 40 (see photo). The amp itself sounds fine for practice, though it would never be loud enough to gig with (you're probably not considering using it for gigging anyway). The built-in preset models are a lot of fun to play with, and reasonably authentic. Dedicated tweakers will no doubt be able to get even more out of the models by fiddling with the pedal settings. I can't imagine anyone not being able to dial in the sound(s) they want for practicing. I have only played around a little with the backing tracks feature, but in my opinion it justifies the purchase all by itself. Nothing helps make practice less tedious than actually *making music,* and the backing tracks facilitate that nicely. There is still much left to explore, especially the feature where the Spark 40 will provide you the chords for songs you give it to analyze, and its ability to slow songs down to help you master them. I will say that under certain conditions there is an awful hum produced by the Spark 40. I plan to upgrade the power supply, but in the meantime I was able to tame the hum by switching cables (went from a coiled Vox to a regular DiMarzio). I will update this again if the hum problem returns. * * * * * * * * * * I got a pleasant surprise today when my Spark 40 arrived ahead of schedule! Amazon said to expect it on May 20-25, but it's May 19 and the amp is safely here. I will supplement this review after I have had more time to play with the device, but my initial reactions are that it is a handsome and solidly-built product. The ergonomics are excellent, and the knobs turn easily and smoothly. The sounds I've gotten out of it so far are fine for a practice amp, and I look forward to digging deeper into its capabilities. I'm planning on using it in combination with a Samsung Galaxy Tab A7 tablet. The Positive Grid app works on my phone but it isn't a large enough display to be useful to me. The tablet should be here in a day or so, and once I have got things set up properly I will post an updated version of this review. ... show more

    • Amazing tones!
Color: Black
The Spark 40 Amp is a versatile and feature-packed guitar amplifier that has garnered a lot of positive feedback from guitarists. However, it's not without its drawbacks. Here's a breakdown of the good and the bad aspects of the Spark 40 Amp, according to customer reviews. The Good: The sound quality of the Spark 40 Amp is impressive, with a wide range of tones and effects that can be customized using the mobile app. The Bluetooth connectivity and the ability to play along with songs make it a fun and engaging practice tool. The built-in tuner, metronome, and USB audio interface are convenient features that make recording and practicing easier. The 40 watts of output is sufficient for small to medium-sized gigs and rehearsals. The amp is lightweight and portable, making it easy to transport to gigs and rehearsals. The user interface is intuitive and user-friendly, with a large and clear display. The Bad: Some customers have reported issues with the Bluetooth connectivity, with the amp occasionally dropping the connection or experiencing latency issues. The mobile app can be buggy and occasionally crashes, which can be frustrating. The built-in effects are not as high-quality as standalone pedals, which may be a concern for more discerning guitarists. Some customers have reported issues with the durability of the amp, with components occasionally failing after extended use. Overall, the Spark 40 Amp is a well-regarded amplifier that offers a lot of value for its price point. While it's not perfect, its impressive sound quality, versatile features, and user-friendly interface make it a great option for guitarists looking for a reliable and affordable amp. ... show more
