Top-level practice tools are a must to keep your chops razor sharp. This holds equally true for aspiring shredders and legendary virtuosos like Steve Vai, who is so enamored of his Spark Mini that he admits, “I never travel without this little friend.” Thus, Steve teamed up with Positive Grid to design the Spark Mini Vai, a fine-tuned Spark Mini that is upgraded with exclusive aesthetics and a quartet of curated presets. Just like the original Mini, this little box shatters all expectations of what a portable practice amp is capable of, boasting a unique dual angled-speaker design that utilizes a personalized EQ, omnidirectional bass response, and custom damping to produce a tone to match amps several times the Mini’s size. More than 100,000 additional tones and presets are available via the Spark app, and you also get a plethora of practice tools, including the ability to play along, slow down, or loop tricky sections of your favorite songs for complete fingerboard mastery. Add in the built-in tuner, Bluetooth audio streaming capability, audio interface functionality, and a smattering of loops and backing tracks from Steve’s catalog, and the Spark Mini Vai is just about the perfect practice tool to sharpen your 6-string skills.
To better suit Steve Vai’s signature style, the Spark Mini Vai wears a completely redesigned exterior. Instead of the standard black or white Tolex of the Spark Mini, the Spark Mini Vai features a deep red burgundy coat paired with a captivating and complex Mandala grille cloth. What’s more, this signature Spark also includes a matching Positive Grid burgundy cable emblazoned with Steve’s “Vai” logo.
In addition to these aesthetic upgrades, the Spark Mini Vai also boasts a collection of loops and backing tracks pulled from Steve’s rich catalog, as well as four new Steve Vai-curated presets:


The Spark Mini Vai’s built-in USB-charge battery delivers up to eight hours of uptime, fully freeing you from the restraints of the power cord! Wherever you go, the Spark Mini Vai’s small size, lightweight design, and long-lasting battery allow it to easily follow, from jamming out around the house to tossing in a backpack for your next guitar lesson. Plus, when it’s time to get serious, the Spark Mini Vai doubles as an audio interface, allowing you to directly hook your guitar up to your DAW of choice for effortless home recording.
One of the Spark Mini Vai's most appealing features is its nearly limitless assortment of pro-grade presets. In our tests at Sweetwater, it was ultra-quick to dial just about any tone we were feeling, from compressed country cleans to fire-breathing metal gains. App-based browsing makes it easy to dial in the tone you're searching for, and the Spark app's stunning amp, effect, and pedal emulations allow you to explore the entire sonic range of guitar tones!


Don’t let the “Mini” in the name fool you; this amp boasts a big, big sound that defies its portable size! Sporting two angled speakers pushing 10-watts of power, the Spark Mini Vai can take you from whisper-quiet bedroom-level practice volumes to a huge, surrounding punch that’s more than loud enough to cover impromptu jam sessions and street performances. Key to this formula is the Stealth Design Passive Radiator on the bottom side of the Spark Mini Vai, allowing for a formidable bass response that would otherwise be impossible on an amplifier of this small stature! Plus, all the qualities that make the Spark Mini Vai an exceptional guitar amp are equally beneficial when using this little box as a Bluetooth speaker, especially when jamming along with your favorite tracks.
A powerful playback system and a vast library of sounds are just half of what sets the Positive Grid Spark Mini Vai apart. Through the app, you'll find countless ways to round out your music-making journey.
