Positive Grid SPARK 2 - Refurbished

Historical Context and Positioning in the Range

The Positive Grid Spark 2 represents the 2nd generation of the "smart" amp that popularized connected home playing. It retains the DNA of the original Spark while adding a next-generation DSP, speaker IRs, and musical AI tools. Within the lineup, it sits above ultra-compact formats to offer more power, wider dispersion, and full studio integration.

Who This Amp Is For

Designed for guitarists and bassists from beginner to advanced levels, the Spark 2 excels in home studios, rehearsals, and small gigs (via line outputs to PA systems). It covers a broad range of styles, from clean funk and folk to British crunch, modern high-gain saturations, and bass slap-all without rewiring or reconfiguring your setup.

Features and New Additions

Its preset architecture allows up to 3 pre-amp effects, 1 amp model, and 3 post-amp effects for a clear and efficient signal flow. The 60-second looper and built-in drum rhythms turn your ideas into instant demos. The LED display tuner simplifies tuning. On the hardware side, the 50 W class D amp drives two 4" full-range speakers behind custom angular horn cabinets, ensuring a wide and homogeneous stereo image.
The connectivity is comprehensive: 6.35 mm instrument input, 3.5 mm headphone output for silent playing, stereo line inputs/outputs (L/Mono & R), and 3.5 mm auxiliary input. For recording, the 24-bit/44.1 kHz USB audio (1 input x 2 outputs) provides clean capture without an interface. On the wireless side, Bluetooth 5.0 and Wi-Fi control the app and audio playback. The AI features "Spark AI Beta," "Smart Jam," and "Auto Chords" speed up tone searching, responsive accompaniment, and chord analysis.

Sound

Modern modeling, class D power, and speaker IRs deliver a very natural response: spacious cleans with good headroom, organic crunches with nice attack, and tight, precise high-gain tones. Dynamics remain lively at low volume, while the wide dispersion preserves nuances in the room. Dedicated guitar, acoustic, and bass presets ensure a coherent and musical output, from airy picking to powerful rock riffs and percussive slap.
