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

Buying advice: small practice bass amp
Match watts and speaker size to practice
Watts set the power an amp puts out, and speaker size shapes the low end it can move. The Ktaxon pairs 40 watts with an 8-inch speaker, while the Hibilly pairs 3 watts with a 3-inch speaker. A higher wattage and a larger speaker suit players who want more low end for practice, while a lower wattage and a smaller speaker suit players who want a desk or bag-size amp for short sessions.
Use the headphone jack for private practice
A headphone jack lets you practice without sound from the speaker. The Ktaxon, the Vendrato, the Flatsons and the Caline each have a headphone output or jack. Plug in headphones and practice without using the speaker while you work through exercises at home. Check the jack size in the specs, since the Vendrato uses a 6.35mm headphone output while the Flatsons uses a 3.5mm headphone jack.
Compare EQ, effects and play-along inputs
Tone controls decide how much you can shape the bass before it reaches the speaker. The Vendrato and the Flatsons each have 3-band EQ with BASS, MID and TREBLE controls, and the Flatsons adds sweepable MID FREQ, COMP and REVERB. The Caline adds Compressor and Boost knobs plus Bluetooth and an auxiliary input for play-along tracks, while the Flatsons streams backing tracks wirelessly or through AUX. Pick the control set that matches the music you practice with, and check the inputs before you buy.
