Positive Grid Spark LIVE Review: 10/10 Rated Amp Now $110 Off!

Sweetwater is offering a range of deals across Positive Grid’s product line, including a generous $110 off its Spark LIVE combo amp and PA system. The Spark LIVE is a 150-watt four-channel combo amplifier and PA System all in one. We included it in our round-up of the best amplifiers for all styles and budgets last year, highlighting it as the best choice for buskers and players on the go. We even scored it a flawless 10/10 in our original 2024 review. The Spark LIVE is not just a “big Spark”. It hosts Positive Grid’s Sonic IQ technology making it pack a punch, which is essentially a combination of hardware and software technologies such as dynamic range compression, vocal clarity enhancement, virtual bass augmentation and more, all driven by a computational audio chip.
