Positive Grid Spark MINI Vai Modelling Combo

Steve Vai Edition Portable Smart Modeling Amp

Modeling amps have become much more than basic practice tools, and the Positive Grid Spark MINI Vai highlights the intersection of artist collaboration and portable smart technology. This special edition 10-watt combo compresses the Spark ecosystem — with AI-powered tone matching, Smart Jam, and access to over 100,000 user presets — into a stereo amplifier that slips easily into a gig bag. Developed in partnership with three-time GRAMMY Award winner Steve Vai, this model delivers unique presets and signature visual details not found on any other Spark unit.

Exclusive Vai Presets and Signature Design

What stands out are the four presets Steve Vai personally crafted — Fresh (crystal-clear clean), Mild (bluesy edge-of-breakup), Hot (distorted rock rhythm), and Fire (saturated lead tone). With the Fire preset, players get a chain of noise gate, compressor, green-style overdrive dialed to the max, and an American high-gain amp model paired with delay and reverb, illustrating Vai’s approach to fluid lead tones. Beyond these sounds, the Mandala grille references the Hydra guitar, while burgundy Tolex with gold piping and the included 3 m braided cable with 24K gold-plated connectors give the amp a visually distinct identity.

Modeling Power and Onboard Effects

Access to a broad palette of amp characters and effects lets players cross genres from shimmering cleans to high-gain metal with no external pedals required.

• Amp Models: 33 — covering American clean, British crunch, high-gain modern, and boutique voicings
• With 43 onboard effects, including noise gate, compressor, distortion, modulation, EQ, delay, and reverb, the creative options are extensive.
• Signal Chain Routing: fully editable via Spark app — drag-and-drop block arrangement with per-parameter control

Positive Grid and Steve Vai: A Signature Collaboration

Positive Grid established its reputation with the Spark series — smart amps uniting advanced modeling with app-driven features like AI tone matching and cloud-based preset sharing. This model marks the first artist signature in the Spark family, built alongside Steve Vai, whose career includes the genre-defining Passion and Warfare. Vai personally created the four presets and contributed exclusive backing tracks from Building the Church, Dust, and Avalanche.
