A Pocket-sized Revolution in Portable Amplification

Standing less than 4 inches tall and equipped with a humble 2-inch speaker, the Positive Grid Spark GO ultra-portable smart guitar amp and Bluetooth speaker delivers 5 watts of full-range tone worthy of an amp several times its size over. By utilizing Positive Grid’s computational audio technology, Spark GO breaks free from the traditional tonal barriers imposed on portable practice amps, then pairs that power with the company’s comprehensive Spark software architecture. The result? An incredibly inspiring hybrid practice amplifier/Bluetooth speaker with four built-in preset slots and some 50,000 more patches available via the Spark app. As if that wasn’t enough, a comprehensive set of practice features — including Positive Grid’s AI-enabled Smart Jam and Auto Chords — make woodshedding easier than ever, while the onboard audio interface functionality makes it a breeze to lay down your tracks using your favorite Spark patches. But that’s not the half of it: a built-in tuner, line out, headphone hack, custom EQ scenarios, 10-hour battery life, and more push Spark GO far past the realm of the “practice amp,” truly redefining the potential of a pocket-sized amplifier.

Harness the power of computational audio

Don’t be fooled by Spark GO’s compact frame — this little amp’s loud, full-range projection defies all expectations! It’s a truly remarkable design comprising a custom-designed 2-inch speaker that harnesses the power of computational audio to punch well above its weight class. Moreover, Spark GO boasts four built-in preset slots, with countless patches to pick from on the Spark mobile app. Whether you’re looking for a portable way to sharpen your shred chops or practice your next singer/songwriter performance, the Positive Grid Spark GO packs uncompromising tonal might into a pocket-sized package.

50,000 patches to GO

Right out of the gate, Spark GO comes equipped with a whopping 33 unique amplifier models and 43 effects, all inspired by legendary gear in music history. From searing arena shred to pristine jazz to effect-laden shoegaze, there’s no style that Spark GO’s tonal library can’t cover. When testing Spark GO out at Sweetwater, we were particularly impressed by its full integration with the Spark app’s tone-sharing functions, allowing you to experiment with over 50,000 user-created tonal creations or even upload a custom patch to share your refined tonal taste with the rest of the world.

The perfect practice partner

The Spark GO’s full-size tone and exceptional portability make it the perfect practice amp and Bluetooth speaker — and that’s before you get to the Spark app’s suite of practice-enhancing software. Looking to tackle a new song? Auto Chord mode provides custom real-time chord sheets so you can learn right along with the song. Plus, the AI-enabled Smart Jam feature trains itself to your personal tone, playing, and style, then it generates a custom backing track that jams right along with you. And while blasting out licks through Spark GO’s powerful speaker is as fun as it gets, there’s also a convenient headphone jack for silent practice sessions.

Ready, set, record

Once practice wraps, Spark GO doubles as a pocket-sized audio interface for effortless recording. Plug your Spark GO into your computer to lay down your next track using Positive Grid’s vast library of pro-level amplifiers and effects.

Carry-on with this amp + Traveler guitar

Flying to Costa Rica with just a carry-on backpack, and unwilling to trust a guitar to checked bags, I got this amp, my headphones, a Traveler Ultra-Light guitar, and a USB wall-wart. It all fits in a daypack with the headless neck of the Traveler just poking out of the pack's top zipper. Also a 1/4" cable and a fat Lekato strap to make the Traveler playable. The other problem with the Traveler is the awful pickup. So I downloaded some patches for the Spark GO which made the tones enjoyable for practicing. There are tons of patches with amp modeling and basic "pedals" you can tweak, like Chorus and Delay. Through the headphones it sounds great, and won't disturb folks listening to birds and howler monkeys. The speaker is totally fine for practice levels. "Surprisingly good sound" is actually an accurate description. Sounds like a decent Bluetooth speaker, which it is, so you can play tunes from any phone app and jam over them. Guitar signal comes through the 1/4" cable and music app comes through the Bluetooth. Separate volume controls for each. The Spark app had a weird streaming player, but any app on your phone can Bluetooth into the Spark GO. Comes with charging cable but NOT wall-wart. :( Charge lasts a good long time so you can clip this little guy to your belt and dance around the AirBnb untethered. I run it with a tiny looping pedal, but there's not a simple way to get the modeled signal out of the Spark, so the looper and any other real pedal will be before the digital amp modeling, so all loops get the same tone.

WOW I had NO idea how JAM-PACKED this tiny thing is!

Our band is in the desert. We can now rehearse in the middle of the Joshua trees. It's pretty Fn awesome. I discovered the Spark GO at the NAMM Show in 2023. I had no idea that this was something cool with multiple tones that I could actually take with me to gigs as an amp modeler. It blows even the bigger competition out of the water. Check out our videos. Wow! You can barely see it in our photo as we both have the amp, and we hang it from our belt rungs (I had to circle the amps).

Positive Grid Go

It is a pocket monster, much like a Marshall long growl. It's hunger, Play something, The volume is great sitting there beside you. I don't even know how to download the promised amps, and pedals, and I don't even care. I have clean to grunge, on four progressive channels. It is so nice looking and feels so good in your hand, and rechargeable is a new concept that Go latched onto. Take headphone out to input of an amp, and It's a big amp now. I haven't even plugged in headphones, I love the grind and decay of the notes on different channels. I've recorded twice with my mic picking up the amp and me singing. I knew it would be good, I heard some good demos. It's as good looking as a Vox, and Vox is sexy. peace
