Positive Grid Spark MINI Vai — 10-Watt Portable Smart Guitar Amp

Co-designed with Steve Vai, this 10-watt portable smart amp brings studio-grade modeling to a desktop-sized, battery-powered format. The special-edition combo layers Vai's signature aesthetic onto the BIAS-powered Spark MINI platform, adding a Mandala grille, burgundy Tolex, and four artist-built presets. At 1.5 kg with up to 8 hours of unplugged play time, it travels easily between bedroom, backstage, and hotel room. The two-channel design separates guitar and music signals for clean monitoring. The stereo speaker configuration delivers room-filling sound for practice and small jams.

What Makes the Steve Vai Edition Different

The custom 10-foot cable with 24K gold-plated connectors and a 4N 99% pure oxygen-free copper core is a first for the Spark series. Inside the app, four exclusive presets — Fresh, Mild, Hot, and Fire — ship pre-loaded, with backing tracks from Vai's catalog.

Modeling Power and Onboard Effects

The BIAS engine delivers a deep catalog of amp models and effects without a pedalboard, with top-panel controls for preset, guitar, and music volume.

• Amp Models: 33 onboard — American cleans to high-gain stacks
• Effects: 43 total (Noise Gate, Compressor, Distortion, Modulation/EQ, Delay, Reverb)
• Vai Presets: 4 exclusive (Fresh, Mild, Hot, Fire) — artist-built tones

Inputs, Outputs, and Wireless Streaming

Wired, wireless, and USB paths make this stereo combo a Bluetooth speaker, silent-practice rig, and recording interface.

• Inputs: 1/4" instrument + 3.5 mm AUX IN
• Headphone/Line Output: 3.5 mm stereo — silent practice or routing to a mixer
• Bluetooth: 5.0 wireless audio streaming — pairs with mobile devices
• USB Audio: 1 In / 2 Out, 44.1 kHz / 16-bit — direct recording into Mac or Windows DAW

Battery Life, Dimensions, and Build

Bedroom, backstage, and hotel-room players need an amp that fits in a bag and runs all day unplugged.

• Power Output: 10 W Class D
• Battery: 3,000 mAh lithium-ion, up to 8 hours play time — full-day unplugged use
• Dimensions: 146.5 x 123 x 165 mm — fits on a desk or amp stand
• Weight: 1.5 kg — easy carry with the reversible heavy-duty handle

Who Is This Amp For

This combo is the right choice for guitarists who want a portable modeling amp with curated artist tones. Steve Vai fans get his signal-chain philosophy — including the compressor-into-overdrive-into-high-gain-American-amp recipe behind the Fire lead tone — while bedroom players, traveling musicians, and content creators also benefit from the Bluetooth speaker and 8-hour battery.

Positive Grid and the Steve Vai Collaboration

Positive Grid built its reputation on the BIAS tone engine that powers every Spark-series amp. This special edition joins earlier signature editions with players like Jimi Hendrix, with Steve Vai — a 3-time Grammy Award winner known for "Passion and Warfare" — personally dialing in the four presets.
