The Constructive Grid Spark guitar amp was an absolute revelation for numerous hobbyist guitar gamers all over the world. The apply amp modified how (and the way typically) I performed the instrument I’d fallen out and in with for a few many years.

Pound-for-pound it sounds unbelievable (higher than it has any proper to), there are tremendous sensible cell connectivity options to scratch the tech itch, together with a exceptional vary of iconic and totally customizable guitar tones akin to a having load of amps and full bodily pedal board at your disposal. Merely put, it’s in my high 5 items of package ever.

So, I used to be delighted to listen to Constructive Grid was increasing the vary with a Spark MINI – a a lot smaller and extra moveable model that would run off a chargeable battery for as much as eight hours – permitting for off piste shredding.

But, Constructive Grid additionally dangers a part of the unique’s attract by going to a lot smaller audio system and a a lot much less highly effective amp. The total-size Spark punches above its weight, however tiny apply amps are likely to sound dangerous and there’s by no means been a lot getting round that.

Are the trade-offs price it for an much more accessible expertise? Can the smaller Spark hit the excessive notes like its ground-breaking massive brother?

  • Smaller than its predecessor
  • Can be utilized as a Bluetooth speaker
  • Comparable look as earlier than

The Spark MINI (146.5 x 123 x 165mm) is significantly smaller than its predecessor (190 x 350 x 180mm). However the width is the place you actually really feel it. The amp weighs simply 3.3lbs (1.5kg) in comparison with the 11.46lbs (5.2kg) unique Spark amp. It’s virtually sq. and matches on a normal desk rather more comfortably. 

There are some tangible benefits to this. Firstly, you may hold it on show. Typically that visible cue is sufficient to keep in mind to play the guitar as we speak. Secondly, there’s a useful secondary utilization as a Bluetooth speaker.

After all, you’ll nonetheless have to plug your guitar in and there’s a normal ¼-inch jack enter, in addition to 3.5mm headphone port on the again. Charging the amp is dealt with by USB-C, that means you don’t need to lug an influence brick round with you, and providing way more flexibility for including juice. You might simply cost it within the automobile with USB-A to USB-C cable. The USB-C out allows connectivity to a pc in the event you want to lay down your jam periods with recording software program like GarageBand or the bundled in free obtain of PreSonus Studio One Prime.

Constructive Grid has maintained the design integrity of the unique. The vinyl coating with gold piping and speaker grille fabric stays. The amp additionally comes with a fake leather-based strap for carrying round.

Naturally, given the width constraints there are far fewer knobs for on-amp management. There are 4 programmable pre-sets and quantity management for guitar and related music. 

Personally, the absence of the standard bass, treble, reverb, and delay knobs wasn’t actually missed as I’ve all of them zeroed out and deal with these changes by the app-based tones that may be endlessly adjusted on the show.

On the rear is an AUX out in addition to the facility button (now not a satisfying basic change), and a pair button (doubling because the built-in guitar tuner activation) to make the amp discoverable to your cell system.

Whereas it will detract from the portability considerably, Constructive Grid does provide a wonderful little foot change for simply switching between two guitar channels. That is an additional £100/$100. It’s worthwhile although when you have some presets you like to jam out with and saves messing round throughout the app.

Typically altering the channels throughout the app isn’t handy since you received’t need to interrupt your circulation. So, in the event you’re seeking to go from a clear sound to a distorted sound with a great deal of overdrive as you head into the refrain (assume Smells Like Teen Spirit by Nirvana, for instance), you’ll can simply step on the foot change to alter between these pre-set channels. The buttons on the foot change have a pleasant satisfying click on too.


  • Bluetooth 5.0 help
  • 10W of energy
  • 90dB sound strain degree

Naturally, the audio system and amplifiers are smaller than the unique. The Spark Mini has a pair of 2-inch audio system (in comparison with 2x 4-inch on the OG) for stereo sound. Amplification comes with 10W of oomph in contrast with 40W on the sibling.

There’s 90dB SPL @1m most sound degree strain, in comparison with 116dB SPL @1m on the unique. I’ve by no means been capable of totally flex the unique’s muscle as I stay in an condominium, so on the floor it, that is loads loud sufficient for dwelling gamers if the sound high quality can maintain up.

In testing, the sound doesn’t really feel as huge or as rounded as the unique Spark amp, which is to be anticipated given the scaled again innards, however it’s nonetheless greater than room filling, and also you received’t have the ability to go full whack with out annoying the neighbours.

Bluetooth 5.0 connectivity is on board for connecting to your cell system, which has confirmed stable throughout testing. There’s no Wi-Fi connection on both Spark Amp fashions. 

Sound high quality

  • Massive loud, sound
  • Get sound uncooked at greater volumes
  • Bassy efficiency with Bluetooth connection

So right here is the place I used to be anticipating to need to heartily suggest the unique full-size Spark Amp over the Mini and forgo the benefits in value, smaller footprint and on-the-go battery energy. 

The smaller guitar amp (and extension the Bluetooth speaker is), outperforms its measurement to make sure it’s nonetheless an nice sounding apply amp that may get loud sufficient to harass the neighbours.

The unique Spark produced a splendidly rounded, full bodied sound that very a lot defied its personal diminutive measurement. Whereas that isn’t wholly reproduced right here, and sound can get a bit ragged, it smashes any apply amp of its measurement I’ve used earlier than. They often sound such as you’ve plugged your guitar right into a bees’ nest.

The sound will get rawer and a bit garage-esque whenever you push the quantity a bit too far (relying on what you’re enjoying that may be a bonus), however in the principle this amp received’t disappoint within the dwelling setting or in the event you’re simply jamming within the park.

So how do these two-inch drivers do it? Extra seasoned guitar professionals than I appear to assume it’s the downward-facing passive radiator doing the leg work on the low finish to realize an admirable quantity of bass and sub-bass. 

The Spark Mini has additionally changed my Bluetooth speaker in current weeks. It produces a fairly full soundscape with a surprisingly bassy efficiency. Because it sits on the desk, the vibration at mid-volume was a bit distracting regardless of the presence of rubber ft. 

As I discussed earlier, having it on the desk is a superb reminder to select the guitar up a bit extra typically.

I briefly sampled recording with GarageBand on Mac and located that (after updating to the most recent firmware) the amplifier interfaced neatly with the app, immediately recognising it as an enter system. Recorded sounds had been hissy to say the least, however I imagine that to be a problem on my finish, relatively than the app.

Cell expertise

  • App options 10,000 tones to select from
  • Self-record function
  • Android and iOS help

The cell expertise is what transforms the Spark {hardware} from commonplace apply amp (and Bluetooth speaker) into the all-singing, all-dancing tonal sensations that can take a stab at replicating any and each iconic guitar sound you may think about. 

So, if you wish to grasp Slash’s iconic reverb-laced Gibson Les Paul solos you may get a fairly respectable approximation of his amp and pedal arrange. Or if you would like the fantastically clear tones of John Frusciante of the Pink Sizzling Chili Peppers, the Spark amp can have an answer.

The total software program suite is free to anybody who has bought the app, immediately unlocking greater than 10,000 tones (together with consumer generated) and a great deal of different options like Sensible Jam (which provides backing to your jam session), Auto Chords (which can assist you determine the chords to songs), and the flexibility to play together with actual world tracks out of your favorite artists.

There’s a guitar tuner inbuilt and you’ll hook up with Spotify or Apple Music for enjoying alongside along with your tunes and there’s a great deal of attention-grabbing video content material – together with tabbed songs – to discover. There’s additionally a self file function, which lets you seize video recordings of and edit your jam periods, with the choice to incorporate backing music.

We’ve discovered utilizing the Spark app on a pill is a a lot nicer expertise than on the smartphone the place issues can really feel actually cramped and it’s fiddly when utilizing the smartphone. 

Sadly, and this was the case with the unique Spark App, firmware updates for the amp can’t be transferred through the app. It’s good to do it by connecting to a pc through USB.

I don’t have the time or the experience to mess around with limitless settings on the guitar and amp, I don’t have the room or want to purchase and muck about with a great deal of results pedals (distortion, delay, noise gate, and so forth)

For my part the unbelievable array of downloadable and customisable tones that does most of this give you the results you want is the principle purpose to purchase a Spark amp. 

A guitar tone is the distinctive sound it makes and lots of the world’s most famed guitarists have their very own signature sounds and it comes through an abundance of things. The guitar producer and elegance, the bodily pickups used, the on-guitar settings are a few of them. The amp is not any assist right here.

Nonetheless, the amp mannequin, the settings on the amp, and the consequences pedals used are the opposite components, and that’s what the Spark app’s tones try to copy.

There are 33 amp fashions based mostly on basic producers and a complete of 43 results. The group has used these to create hundreds of distinctive tones you too can add your individual spin to.

There are many pre-sets Constructive Grid has created throughout genres (together with bass and acoustic), however the jewels are the group created tones, which allow you to look the ToneCloud on your favorite songs and discover a tone somebody has created aiming to copy that sound.
