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.

Buying advice: acoustic guitar amplifier
Match watts and inputs to your setup
Watts set the output level, and inputs set how many sources play at once. The Yuer amp gives 10 W, the Fender amp 15 W, the Coolmusic 30 W amp 30 W, the Coolmusic BP80 100 W, and the Fishman amp 120 W. Count your sources before you buy: the Coolmusic BP80 has 6 inputs for 2 instruments, 2 microphones and 2 phones or computers, while the Coolmusic 30 W amp has 3 inputs and the Fender amp has two channels.
Check battery power and Bluetooth
Battery power frees the amp from a wall outlet for practice away from home. The Coolmusic BP80, the Coolmusic 30 W amp and the Yuer amp run on rechargeable batteries, while the Fishman and Fender amps run on corded electric power. Bluetooth adds backing tracks without a cable: the Coolmusic BP80, the Fishman amp and the Coolmusic 30 W amp have Bluetooth, and the Yuer amp supports a wireless connection.
Look at effects and outputs
Effects shape the guitar sound before it reaches the speaker. Reverb appears on the Coolmusic 30 W amp and the Yuer amp, chorus on the Fender amp and the Coolmusic 30 W amp, and delay on the Yuer amp. For outputs, the Coolmusic BP80 has a headphone input and a DI output, the Fishman amp has balanced XLR outputs, the Fender amp has a headphone output, and the Yuer amp has a headphone jack.
Frequently asked questions
Do I need a battery powered acoustic amp?
Only if you play away from a wall outlet. The Coolmusic BP80 runs 6 to 8 hours, the Coolmusic 30 W amp 5 to 8 hours, and the Yuer amp 4 to 8 hours on a charge. The Fishman and Fender amps run on corded electric power.
How many inputs do I need for a small band?
The Coolmusic BP80 has 6 inputs for 2 instruments, 2 microphones and 2 phones or computers, which covers a small band. If you play solo, the 3 inputs on the Coolmusic 30 W amp or the two channels on the Fender amp are enough.
What does phantom power do for a microphone?
Phantom power lets a condenser microphone work through the mic input. The Coolmusic BP80 has a 48V phantom power switch for condenser and dynamic microphones, and the Fishman amp has phantom power too.
Can I play backing tracks through these amps?
Yes. The Coolmusic BP80, the Fishman amp and the Coolmusic 30 W amp have Bluetooth for backing tracks, and the Yuer amp supports a wireless connection and AUX input for the same job.
