How we ranked these acoustic guitar amps
Every pick ranks in Amazon's best-seller list for its category and has 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 1
- Mic input weight 1

Buying advice: acoustic amp with reverb
Reverb comes first for this search
Every pick here has reverb, so compare what comes with it. The JOYO adds chorus and delay, the NUX offers Plate and Hall reverb, and the MELONARE gives separate reverb controls for mic and instrument. If you sing and play at once, separate controls let you set the voice and the guitar apart.
Watts set the ceiling, not the tone
Watts measure how much power the amp can put out. Watts run from 150W on the Taylor to 12W on the Ortega, with 80W peak on the MELONARE, 40W on the JOYO and 25W on the NUX. A higher watt figure gives more headroom before the sound breaks up, so match the watts to how loud you play.
Count channels before you buy
A second channel matters when you sing and play together. The JOYO, NUX and Taylor each have 2 channels, with separate controls for guitar and voice on the JOYO and NUX. The MELONARE has mic and instrument inputs, so check whether each input has its own volume and EQ before you buy.
