Positive Grid

collapse expand iconDescription

The Positive Grid Spark GO ultra-portable smart guitar amp ushers in a new era of practice and play. Seamlessly integrated with the Spark app, this pocket-sized powerhouse provides immediate access to amps, pedals, auto chords, Smart Jam mode, and over 50,000 tones in the cloud—all in a unit standing under 4" tall.

Computational Audio Technology Delivers Surprisingly Bold Tone

Don't let Spark GO's diminutive size fool you—under the hood, sophisticated computational audio technology works to produce rich, full-range sound more typical of a much larger amp. Four built-in presets and a massive trove of downloadable patches mean lush cleans, snarling overdrives, ambient reverbs and more are all instantly on tap. An onboard 2" speaker pushes 5 watts of power, filling any room with stunning fidelity.

Practice-Focused Features Make Improving Effortless

Spark GO was designed by musicians for musicians, with practice firmly in mind. Built-in tools like Smart Jam generate AI-based backing tracks in your chosen genre, key and tempo, while Auto Chords provides an onscreen chord chart to help you navigate songs. An onboard tuner keeps your instrument in check, and the audio interface lets you record directly into your favorite DAW. With 10 hours of battery life, feel free to get lost in your craft.

Road-Ready and Built to Last

Weighing in at just over 2 pounds, Spark GO tucks neatly into any gig bag or backpack, ready to accompany you anywhere inspiration may lead. A rugged metal grille protects the speaker, and the included hardshell case adds an extra layer of defense for life on the road. An 1/8" headphone out provides silent practice, while the line out sends your signal direct to a mixer or audio interface. Wherever you roam, Spark GO roars.

Unparalleled Connectivity and Control

The free Spark app places full control over your amp in the palm of your hand. Choose from a massive selection of amps, cabs, mics and effects—including signature gear from world-class artists. Build your own custom presets, change settings in real time and share or download new patches at will. Bluetooth connectivity and the Spark app work together to turn your mobile device into a versatile stompbox, letting you switch between tools without missing a beat.

    Explore the App Before You Send It Back

    After charging it up and plugging into my acoustic/electric, the preset sounds were horrid. Think Les Paul through a fuzz/distortion unit - then hit a power chord then repeatedly flipping the pickup selector back and forth. Changing presets and volume had no effect. Almost sent it back, then read a review mentioning "noise gate setting" which rang a bell, so installed the app and dialed in presets to more suit an acoustic's clarity. Only so much you can do with a tiny speaker... but not too bad for the equivalent of a transistor radio speaker. Bluetooth in your Airpods to get much better sound quality. The app has an amazing amount of effects/amp sounds available - and access to a large library of songs (perhaps alone worth the purchase price). Have not used all of the capabilities together yet, so can't say how well they all play together - or ease/quality of any recording capability. Haven't looked to see if the Airpod's microphone can be utilized in recording. Perhaps an idea for a future update... So in summary, if you are comfortable enough with the technology to load the app and play with the settings on your phone/tablet - it's worthwhile. If you don't plan to use the app (old school, or just don't want the potential pitfalls that reliance on technology can bring), there are probably better choices.

    Nice Design, Tones are meh

    I do like the Spark's general design and I could see it becoming a truly great system. That said, I found it pretty difficult to dial in any really useable edge-of-breakup / bluesy tones. The marshall-y high gain stuff is pretty good, this might be great if you're mostly shredding, especially 80's / hair band style. Beyond that though, the clean and crunchy options are very lackluster in my opinion, pretty muddy sounding and not much better than what you'd get by plugging directly into garageband or something like that. Not even in the same universe as UAFX. Even comparing it to cheaper options, my VOX Amplug unit blows this out of the water as far as producing real amp feel and genuine breakup, its much louder too. I think the algorithms here just need a ton of work. A lot of the fx pedals are not even completely functional... For example- most of the reverbs have MULTIPLE knobs that do absolutely nothing as you adjust them. On a positive note though, its very easy to use overall and one of my favorite interfaces ever for jamming along with Spotify, etc., The tones just didn't do much for me and I'm returning it.

      I use this amp and I connect it to my Marshall DSL so that way I have effects without having to buy the actual pedals.

      Needed a small amp because I was tired of having to lug my Mustang around. This thing is perfect! I came in ready to get a different smaller amp, but the sales guy sold me on this one. I like the app that I can alter the effects as well

      I bought this cute tiny amp for my young enthusiast as an option to have with her for a backup (in case she has a little rehearsal in the school hallway with her bandmates or whatever) and to have fun at home. So far so good, it does exactly that much and sounds decent for the size. Anything to keep the kiddo interested in practicing works for me. #sweepstakes

      This thing is serious. Watch the videos. You will see all you need to know. One tip; to mix/match amps and pedals, double tap them at the top of the screen.

      I like how it's so easy to use, just turn on and plug in, it's got four presets to choose from and an app that is also easy to use where you can change amp settings. It's light weight and looks cool. #sweepstakes

      I know you said it works with acoustic-electric, but would you recommend it? would the tone, etc in the app work well?

      The Positive Grid Spark GO does work with acoustic-electric guitars, and technically it can give you usable tones, especially for low-volume practice, songwriting, and noodling. But whether I’d recommend it specifically for acoustic-electric use depends on your expectations and how you plan to use it. Pros (for acoustic-electric players): Super portable. It’s great for couch playing, travel, or warming up backstage. Tone-shaping options in the app. There are some decent acoustic amp models and effects (like reverb, chorus, delay) that can add nice shimmer to your tone. Battery powered. Makes it a convenient grab-and-go unit. Bluetooth audio streaming. Nice for jamming along with tracks or backing music. Cons / Limitations (specifically for acoustic): Tone coloration. The Spark GO is voiced more toward electric guitar tones, so acoustic models are limited and don’t feel as “natural” or detailed. Even the "acoustic" preset can feel a bit boxy or scooped, especially through the small speaker. Speaker size and fidelity. The tiny speaker doesn’t do justice to the dynamics and air of an acoustic instrument. No DI out. You can’t easily plug it into a PA or mixer if you want to use it live or for recording, unless you're mic'ing it — which defeats the portability. Would I recommend it? Yes, if you’re: Looking for a fun, ultra-portable practice tool for home or travel. Wanting to experiment with tones and effects casually. Primarily focused on electric but occasionally playing acoustic. No, if you’re: Hoping to use it for serious acoustic tone shaping, performance, or recording. Prioritizing a natural, full-range acoustic sound.

      Yes, you can plug a pedal into the Spark. I don't know how metal it will sound.

      No. It will "produce sound/work" but it won't give you any lows and there is a good chance of blowing up a 2" speaker using a bass. I will have a product specialist contact you with other options.

      Not really. It will produce sound but has no low end. If you turn it up, you risk speaker damage.
