A Pocket-size Revolution in Portable Amplification Standing less than four inches tall and equipped with a humble 2-inch speaker, the Positive Grid Spark GO ultra-portable smart guitar amp and Bluetooth speaker delivers five watts of full-range tone worthy of a full-size amp. By utilizing Positive Grid’s computational audio technology, Spark GO breaks free from the traditional tonal barriers imposed on portable practice amps, then pairs that power with the company’s comprehensive Spark software architecture. The result? An incredibly inspiring hybrid practice amplifier/Bluetooth speaker with four built-in preset slots and 50,000 more patches available via the Spark app.
