How we ranked these acoustic guitar amps
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

- Speaker size weight 1

Buying advice: acoustic amp
Compare watts, channels and speaker size
Watts, channels and speaker size are the three specs to compare first. The Fender Best Overall gives 100 watts, an 8 inch speaker and two channels, the COOLMUSIC gives 20 watts, an 8 inch woofer and two channels, and the Fender Runner-Up gives 15 watts, a 6 inch speaker and two channels. Compare those three figures across the amps before buying.
Check inputs, effects and wireless options
Inputs decide what you can plug in, effects shape the signal, and wireless options decide how you play backing tracks. The COOLMUSIC takes guitar and microphone inputs with reverb and chorus effects and Bluetooth, the YUER takes guitar and dynamic microphone inputs with reverb, delay and OTG recording, and the Fender Best Overall takes instrument and microphone inputs with Bluetooth streaming. Match the inputs and effects to the setup you already own.
Look at battery, weight and warranty
Battery life decides how long an amp runs without a cable, weight decides how it carries, and warranty covers the purchase term. The YUER has a 4000mAh battery for 4 to 8 hours, the flatsons has a 3000mAh battery for up to 8 hours and weighs 4.2 lb, and the Fender Best Overall weighs 18 lb with a 2-year warranty. Compare battery, weight and warranty against how you plan to use the amp.
