Standing less than 4 inches tall and equipped with a humble 2-inch speaker, the Positive Grid Spark GO ultra-portable smart guitar amp and Bluetooth speaker delivers 5 watts of full-range tone worthy of an amp several times its size over. By utilizing Positive GridÕs computational audio technology, Spark GO breaks free from the traditional tonal barriers imposed on portable practice amps, then pairs that power with the companyÕs comprehensive Spark software architecture. The result? An incredibly inspiring hybrid practice amplifier/Bluetooth speaker with four built-in preset slots and some 50,000 more patches available via the Spark app. As if that wasnÕt enough, a comprehensive set of practice features Ñ including Positive GridÕs AI-enabled Smart Jam and Auto Chords Ñ make woodshedding easier than ever, while the onboard audio interface functionality makes it a breeze to lay down your tracks using your favorite Spark patches. But thatÕs not the half of it: a built-in tuner, line out, headphone hack, custom EQ scenarios, 10-hour battery life, and more push Spark GO far past the realm of the Òpractice amp,Ó truly redefining the potential of a pocket-sized amplifier. Positive GridÕs Spark Control offers a hands-free, cable-free way to modify your settings, toggle effects, swap presets, control backing tracks, and much more! This footswitch comes loaded with four officially pre-programmed scenarios, but SweetwaterÕs guitarists find that itÕs a breeze to fully customize the Spark ControlÕs operation to fit a more personalized workflow. A 4-month battery life (averaging one hour of play per day) makes it easier than ever to jam out and practice for extended periods. Best of all, the Spark Control requires minimal setup time: simply load up the Spark Amp app on your mobile device and the Spark Control will automatically sync, allowing for instant practice sessions anywhere!
