Constructive Grid’s Spark guitar amps proceed to current the proposition into smaller designs. Following the launch of the battery-powered Spark Mini, the corporate has adopted up with the pocket-sized Spark Go. 

It’s the newborn brother to the game-changing Spark 40 amp, which bundled size-defying sound with an unimaginable vary of app-based digital amp fashions and results to create a really limitless array of absolutely customisable guitar tones. 

It additionally features a load of linked options designed to assist guitarists study and play together with their favorite songs and even jam with a digital band. It doubles as a Bluetooth speaker so you possibly can play alongside along with your favorite tracks.

Identical to the center baby, the Spark Mini, the brand new Spark Go amp does all of that, however with out the necessity to tether to the mains. It has a chargeable battery, making your amplified guitar enjoying actually transportable. On this case, even clipped to your particular person.

Nevertheless, established information means that an 5W amp with a 2-inch speaker isn’t going to provide sound worthy of your guitar enjoying experience.

Learn on for the total verdict…


  • Extremely small soda can-sized construct
  • Design consistency with Spark household
  • Only a few bodily buttons

The Spark Go is across the measurement (125 x 85 x 45 mm) of a Coke can and at 346g, weighs about the identical too. As guitar amplifiers go, it’s tiny and might even match into your pedal board. A lot smaller than the Spark Mini and a fraction of the dimensions of the Spark 40, which itself is famend for its compact measurement.

The benefit of that is true portability. It’ll go into your guitar bag simply and, relying in your laborious case, may even slot in there too.

It’s rectangular with curved edges, however with a flat backside meaning it’s in a position to rise up comfortably, with the rubber silicone coating across the machine serving to it keep rooted to the floor. That may be simply eliminated, nevertheless it’s useful for gaining buy on the floor and defending the amp. After I unboxed it, I believed a kickstand would have been a useful addition, however I haven’t knocked the Spark Go off stability but. You may as well place the amp with the speaker going through instantly in direction of you or with the speaker going through upwards. 

The Spark Go does an honest job of sustaining constant design language with the replaceable speaker plate matching the opposite two fashions. Constructive Grid additionally provides you an alternate choice within the field. 

By way of on-board controls, this model eschews nearly all buttons to carry the bodily controls right down to the naked bones. Identical to the Spark Mini, there are not any dials for bass, treble, delay, reverb, and so on., which you’d see on a conventional amp (or the Spark 40). 

It’s not that vital as you possibly can modify these settings on the digital amp and pedals throughout the app. Nevertheless, it does make the Go much less helpful should you don’t plan on connecting by means of the app each time. Bear in mind, you possibly can at all times save your 4 favorite tones to the amp so that you don’t want the app in any respect.

The ability/Bluetooth pairing button is mixed. Then there’s a gold button for switching between the 4 doable pre-set tones, which may be altered to your most well-liked defaults although the Spark app. There’s a quantity rocker for Bluetooth music and a quantity dial for the guitar sound built-in into the usual jack enter, enabling you to regulate accompanying music and guitar quantity independently.

There’s additionally a 3.5mm headphone jack if you wish to pump these guitar sounds instantly into your ears. It could act as a line out should you want to connect with a bigger speaker. And there’s a dual-purpose USB-C output for charging and connecting to your pc for recording. 

Lastly, there’s a golden strap button (with a pair of strap choices) that lets you create a loop so you possibly can connect the amp to your belt land stroll round the home rocking out. You received’t even want to fret about tripping over the cables as you need to use a brief patch cable between the guitar and amp.

The Spark Go is rated at 5 watts and has a tiny little 2-inch speaker with a passive radiator. The lithium battery lasts eight hours, so as soon as charged through USB-C you’re good to go for a day trip. In fact, you possibly can extend that with a battery pack if needed.

A guitar tone is the distinctive sound it makes. Most famous guitarists have a signature sound that derives from their arrange and the way it’s tweaked. The guitar itself performs a giant half, as do the pickups, and on-guitar settings (suppose Tom Morello of Rage Towards The Machine). These are unrelated to the amp and pedal arrange.

Nevertheless, the amplifier used (suppose Marshall, Orange, and so on.), the settings on the amp, and the results pedals (delay, distortion, reverb, and so on.) used are the opposite key elements, and that’s what the Spark app’s tones try to copy.

There are 33 amp fashions obtainable primarily based on traditional producers and a complete of 43 results. The neighborhood has used these bases to create 1000’s of distinctive tones you too can add your personal spin to.

If, like me, you don’t have the time, funds, or experience to finely tune a guitar sound through the amp or a giant grand pedal board, that is the place the Spark vary actually comes into its personal.

I consider this unimaginable array of downloadable and customisable tones (you possibly can add your personal tweaks to the tweaks), is the principle motive to purchase these merchandise. Your favourites may be rapidly saved and switching between them occurs in a few faucets. 

All this for $130 is sort of the steal, coupled with the very fact the amp can work as a go between for plugging your guitar into your pc to report with these tones.

There are many sensible options to go along with the tones, and these are glorious for newbie and intermediate guitarists. Sensible Jam as an example will conjure a backing monitor with to accompany your personal enjoying fashion, if you choose from one of many pre-set profiles. 

Spark amp smart jam

Jarvis, as an example is “a rocker at coronary heart and he listens to your enjoying in actual time and adjusting your dynamics and complexity on the fly.” There are alternatives for funkier or bluesier gamers and the function listens to eight bars of music earlier than starting to play together with different devices. It’s nearly such as you’re enjoying together with the total band, and it’s nice for individuals who don’t have one.

The cell expertise has at all times been intrinsic to the Spark amps, reworking the merchandise from commonplace (albeit over-performing) follow amps to a limitless world of tones and performance that’ll have a stab at replicating any guitar sound. Out of your guitar heroes, to a very customized sound that works with what you’re enjoying.

It might be Slash’s reverb-lased Gibson Les Paul solos, or a fantastically clear John Mayer-like tone. Both method, the Spark amp could have an answer that seeks to copy the set-up of these icons, from amp fashions to the results pedals.

I discovered it helped me with my timing quite a bit. Once you’re noodling away by yourself, it will possibly get a bit everywhere. This saved me disciplined and in rhythm with the drummer. 

The total software program suite is free to anybody who has bought the app, immediately unlocking tens of 1000’s of tones, together with these generated by the neighborhood. However there are a great deal of different options like Sensible Jam (which provides backing to your jam session), Auto Chords (which transcribes the chords to well-known songs), and the power to play together with actual world tracks out of your favorite artists, albeit by means of the mixing of YouTube movies. Extra on these later.

There’s a guitar tuner built-in to the amp with the LED lights for pre-sets performing double obligation right here too as a visible indicator in case your observe is sharp or flat. It’s additionally simple to connect with Spotify or Apple Music to play alongside along with your tunes. The app additionally has a comparatively new self-record function for capturing video (full with backing tracks) for straightforward social media posting.

On the opposite Spark amplifiers, I most well-liked utilizing the pill model of the Spark app, however that’s towards the spirit of the Spark Go, which is all about portability. Issues are cramped and fiddly on the smartphone, however not annoyingly so.

Sadly, and this was the case with the opposite Sparks, firmware updates for the amp can’t be transferred through the app. You should do it by connecting to a pc through USB with the bundled-in cable.

As talked about above, Auto Chords is a function transposes chords from any track you feed it from a linked Apple Music or Spotify account. These are useful for learners, however the interface generally feels fairly restricted. Given the app works as a Bluetooth speaker too, you possibly can play alongside. Once more, superior for the beginner rocker.

Sound High quality

Greater sound than anticipated

Greatest suited to reasonable quantity ranges

The hallmark of the unique Spark 40 amp was its size-defying sound. It’s simple to neglect taking a look at its child brother that the Spark 40 – a reference to the 40W speaker – was the OG little amp that might. For a follow amp, it has no proper sounding as refined because it does at excessive and low volumes. It was even loud sufficient for some mild gigging or an open mic with out shedding constancy. I beloved it and have it 5 stars.

The Spark Mini made some sacrifices with the speaker measurement (10W), however nonetheless overperformed. The Spark Go, in the meantime is way smaller too with a 5W speaker. Once more, I tempered my expectations solely to have them exceeded once more.

Following immediate connectivity with the Spark cell app through Bluetooth (it appears sooner than the opposite amps), I used to be blown away. The sound fills the room at high quantity with out being too abrasive. You’ll be notified with a little bit “cha-chuck” sound while you attain the highest quantity because the dial rotates perpetually in each instructions.

Nevertheless, that is an amp finest utilised for taking part in at reasonable quantity ranges. On the low finish its tinny and weak, and on the highest finish the sound turns into fractured. The completely happy center floor is heat and surprisingly refined and nuanced, whether or not you’re enjoying a clear tone with delay or going for a heavier overdriven sound with a little bit reverb. You received’t disturb the neighbours and it’ll be loud sufficient so that you can really feel such as you’re rocking out.

As a lot as I relished with the ability to stroll round the home with the amp hooked up to me, you’ll get numerous suggestions this manner.

For what it’s value, I completely beloved enjoying with this factor exterior too. Simply taking it out into the yard and laying it on the bottom introduced out some beautiful sounds that blended properly with the ambient noise round. It was positively loud sufficient to listen to clearly because the visitors glided by.

The one drawback was the led pre-set lights, that are barely seen in daylight, even on a dark day with loads of shade. A minor quibble.

Remaining Ideas

Constructive Grid has performed one other blinder with the Spark Go. The Spark Go requires compromises by way of sound high quality, however the amp nonetheless outperforms its bodily limitations. For customers searching for final freedom by way of portability, wearability of the amp, and on-the-go battery energy, it might be the proper answer.

The Spark Go isn’t wherever close to as loud because the Mini and once more, the restrictions of the smaller speaker change into extra noticeable in its smaller type issue.

Personally, I’d purchase the Spark Go over the Mini for that added portability, and the power to play with the amp in your particular person (kind of) wirelessly. You lose sound high quality with the smaller speaker, however I believe it’s value it to not discover carrying an amp with you. 

In a perfect world, the Spark 40 for the house and the Spark Go for on the go.
