smart amp impressed me when I reviewed it in the July 2020 issue, with its 40 watts of power, Bluetooth audio streaming, a huge library of amp and effect tones powered by the company’s BIAS tone engine, Auto Chords to analyze songs and display chords, and a virtual band for jamming on your own. The gear maker downsized Spark’s hardware last year when it introduced Spark MINI (reviewed September 2022), while adding new features like Smart Jam Live, which analyzes your playing and automatically generates bassyou can toss in a tote bag or dangle from its wrist strap. And it packs nearly all the features of its big siblings via the free Spark App.
