How we ranked these bass 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 2
- DI / XLR out weight 1

Buying advice: bass amp with distortion
Compare watts and speaker size
Watts are the amp's power output, and speaker size is the diameter of the speaker. The Peavey and the Fojill each run 20 watts, while the Hibilly runs 3 watts. The Peavey has an 8 inch speaker, the Fojill has a 6.5 inch speaker, and the Hibilly has a 3 inch speaker. Compare both figures on each amp before you buy.
How distortion works on these amps
Each amp here adds distortion its own way. The Peavey volume control adds a Transtube distortion boost, the Fojill has a distortion gain control with bass, treble, middle and presence tone controls, and the Hibilly switches between Clean, Overdrive and Distortion modes. Try the distortion control with the EQ set flat, then adjust the tone controls to taste.
Headphone jacks and batteries
A headphone jack lets you practice through headphones, and a battery lets you play away from an outlet. The Fojill has a headphone jack and an aux input for songs with accompaniment. The Hibilly runs on a built-in 1200mAh rechargeable battery and comes with a leather carry strap. All three amps here carry a 1-year warranty.
