Positive Grid’s Spark MINI Vai is a compact and feature-packed guitar 10-Watt Class D amp that aims to provide versatility, portability, and exceptional sound quality for musicians on the go. Designed as a smaller sibling to the popular Spark Amp line, the Spark MINI packs a punch with its array of features in a portable size.
Design and Build Quality
The Spark MINI Vai exudes a sleek and modern design, with a compact form factor (146.5 x 123 x 165 mm and 1.5 kg) that makes it ideal for both home practice and on-the-go jam sessions. Its sturdy construction (Tolex finishing and an interchangeable grille cloth at the front covering two 2” speakers) ensures durability, while its lightweight nature makes it easy to transport. The control layout is intuitive, featuring knobs for guitar volume, music volume, power/Bluetooth pairing, and preset selection, plus an onboard tuner with an LED display. The Spark MINI Vai is a custom-design edition with a few differences to the original MINI: Mandala front grille, Burgundy Tolex, a burgundy/gold reversible heavy-duty handle, a 10’ guitar cable featuring 24K gold-plated connectors and wrapped in a durable burgundy weave nylon jacket, and 4 custom Steve Vai presets.
Sound
Its sound is as addictive as it is powerful. Thanks to its design and its speaker configuration (stereo – 2″ custom-designed speakers + 1 passive radiator at the bottom), the Spark MINI has the best-balanced sound from all the Spark amp series (compared with the Spark 40, the sound is less boomy, and compared with the Spark GO, is less nasal).
