Flawed Hardware, Broken Software, and Disappointing Support: Moving On From the Spark 40
I am writing this review to warn other guitarists before they invest their hard-earned money into the Positive Grid ecosystem. I have owned a Spark 40 since July 2023, and it has been a deeply frustrating experience.
The amplifier is fundamentally unstable. It behaves erratically, the audio cuts out completely during normal playing sessions, and the software constantly glitches. To make matters worse, the process to update the firmware via a computer is completely broken, clunky, and unnecessarily complicated. A practice amp shouldn't require an advanced IT degree just to keep it from glitching out mid-jam.
When I contacted customer support about these persistent defects, their immediate response was to push a sales pitch telling me to spend MORE of my own money to buy their newer Spark 2 model. Offering a "discounted upgrade" as a solution for a flawed piece of original hardware is completely unacceptable customer service.
I am done with digital modeling headaches and am moving entirely to a reliable, 100% analog setup. If you want an amp that actually functions when you flip the power switch, look elsewhere.
