Summary
In the opening segment of this United States of Analog video, host Bob introduces an unusual product for his typically audiophile-focused channel: the Positive Grid Spark Mini guitar amplifier. This 10-watt portable device doubles as a Bluetooth speaker and represents a departure from his usual turntables and DACs. He’s reviewing the Steve Vai signature model, which costs between $200-270 depending on the version, and includes features like 8-hour battery life, a companion app with AI capabilities, and four built-in presets.
Bob is refreshingly honest about his limited guitar skills, describing himself as more of a collector than a player who knows basic “cowboy chords” but wouldn’t confidently jam at Guitar Center. He positions the Spark Mini as an “aspirational device” – perfect for intermediate players rather than serious musicians who likely already own high-end gear. The amp appeals to him for casual use scenarios like hotel room practice or living room noodling.
The host appreciates the included accessories (10-foot cable and carrying strap) and the overall value proposition. He plans to test the device with his rarely-played George Harrison limited edition all-rosewood guitar, setting up what promises to be an entertaining demonstration given his self-admitted musical limitations. Bob also teases an embarrassing story from his youth that will explain his musical shortcomings, adding a personal touch to this gear review.

Summary
In this final portion, the host provides a comprehensive evaluation of the Positive Grid Spark Mini guitar amplifier, acknowledging both its strengths and limitations. He praises the device’s wireless design, compact size, good drivers, and AI/app integration, noting that it made him feel like a real musician when playing bass with backing tracks.

The host specifically cautions against purchasing the Spark Mini solely as a Bluetooth speaker, arguing that dedicated options from JBL and Marshall offer better value at similar price points.

His final assessment positions the device as feature-rich and worthwhile for its intended guitar amp purpose, with Bluetooth connectivity serving as an excellent value-added benefit.
