The article dives into the world of digital amp modeling with the Spark 2 from Positive Grid—a portable, 50-watt practice amp that packs a punch with built-in Bluetooth, USB-C connectivity, and a smartphone app loaded with downloadable guitar tones and effects. At $300, it offers a compelling mix of tactile knobs and smart software, featuring an M7 chip that doubles its DSP power for "smoother transitions between tones, richer effects, and an expanded memory for presets and loops." While the amp may not deliver studio-quality, tube-like sound, it's an ideal, easy-to-use tool for jamming, basic recording, and practicing on the go, complete with AI features like Smart Jam and Spark AI to help shape your tone—though the latter can sometimes feel slightly hit-or-miss.

Key Points:

• Digital Amp Modeling: The Spark 2 runs advanced digital simulations of amps and effects, enabling users to download thousands of tones via an accompanying smartphone app.
• Portability and Ease of Use: Designed as a compact, lightweight, and battery-powered device (optional battery pack available for $79), it’s perfect for on-the-go practice and live jamming.
• Connectivity and Interface: Equipped with Bluetooth, USB-C, a guitar input, two quarter-inch line-out jacks, and a headphone jack, it ensures versatile connectivity, whether streaming or recording.
• Enhanced DSP Power: The new M7 chip doubles the processing power, allowing for richer effects, smoother tone transitions, and an expanded memory for storing presets and loops.
• AI Features: Alongside the basic app controls, AI tools like Smart Jam (which adapts backing tracks in real time) and Spark AI (a natural language tone-shaping engine) add a futuristic twist—though, as noted in the review, “there was always a herky-jerky quality” with some AI-adapted backing tracks.
• User-Friendly Design: Despite its digital focus, the Spark 2 maintains the tactile simplicity of physical knobs and buttons, making tone adjustments straightforward and accessible without resorting to a computer.
• Position in the Market: Ideal for practice, jamming, and basic recording, it isn’t designed to compete with high-end studio rigs but fills a niche alongside products like Kemper Profiler, Line6 Helix, NeuralDSP’s Cortex pedalboards, and IK Multimedia’s Tonex gear.

This blend of hardware convenience and digital innovation makes the Spark 2 a fun, creative tool for musicians who want to rock out without the hassle of complex computer setups.
