The Positive Grid Cab is honestly a brilliant addition for anyone using the Spark or Spark MINI who wants a proper amp feel. The first thing that stands out is how full and clear the sound is—you get tight low-end, articulate mids, and enough top-end sparkle for high-gain tones or clean, ambient playing. It’s surprisingly loud for its size, but it never sounds harsh or boxy.
Build quality is solid too. The cab feels sturdy, portable, and looks great next to the Spark amp. Hook-up is simple: plug it in and your tones immediately feel more “amp-like” and three-dimensional. For home practice, jamming, or even small gigs, it adds a huge upgrade to the Spark experience.
If you’re a guitarist who wants bigger, more realistic amp presence without needing a full stack, the Positive Grid Cab is a smart buy. It makes the Spark sound more alive, more dynamic, and way more fun to play through.
