The bottom line
The Positive Grid Spark MINI is our top pick for an acoustic guitar amplifier. It has powerful sound, ease of use, and portability with a rechargeable battery for up to 8 hours of use. Its smart app with over 50,000 tones and features makes it versatile for electric, acoustic, and bass guitars. The closest alternative is the Fender Acoustasonic, which has 40 watts of power and dual input capabilities but lacks the app integration and portability of the Spark MINI. For a budget pick, the Fender Frontman 10G has a compact design and versatile tones at a lower price, though it lacks the features of the Spark MINI.
