How we ranked these 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.
- Power weight 3
- Speaker size weight 2
- Built-in effects / amp models weight 2

Buying advice: guitar amp for vocals
Match channel count to your mics
Vocals need a channel built for a microphone, so confirm that at least one channel takes a mic before you buy. Two-channel amps here cover one singer playing guitar, while the COOLMUSIC BP60D names dedicated mic channels with separate reverb knobs for each voice. The Fender and Fishman amps give two channels for instrument or microphone, which suits a solo singer-songwriter who switches between lead and backing parts.
Weigh watts against where you play
Watts are the main way to compare these amps for loudness, and the range here runs from 20 W to 120 W. The COOLMUSIC AC20 at 20 W names practice, solo performance and studio among its uses. The COOLMUSIC BP60D at 120 W names street busking, small band gigs and outdoor live events.
Check phantom power for condenser mics
Condenser microphones need phantom power from the amp, while dynamic microphones do not. The COOLMUSIC BP60D names 48V phantom power on its MIC 1 channel, and the BOSS ACS-Live names phantom power on its microphone channel. Pair either with a condenser microphone. If you sing into a dynamic microphone, any of the five amps here takes it, since each one has a channel built for a microphone.
Frequently asked questions
Can a guitar amp handle vocals too?
Yes, if it has a mic channel. Every amp on this list has at least one channel built for a microphone, plus EQ and effects to shape the vocal sound.
How many watts do I need for singing with guitar?
It depends on the venue. These picks range from 20 W to 120 W, and the highest-watt amps name live performance and outdoor events in their data.
Do I need phantom power to sing through an amp?
Only with a condenser microphone. The BP60D and the ACS-Live name phantom power on a mic channel, and dynamic microphones work without it.
