How we ranked these bass 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
- DI / XLR out weight 1
- Headphone output weight 1
Buying advice: bass amp for keyboard
Match wattage to how you practice
Wattage is the power figure for an amp, and it is one of the first numbers to compare. The Fender Rumble 500 V3 gives 500 watts, the JOYO BA-30 gives 30 watts and the Fender Rumble 15 gives 15 watts, so the spread here is wide. Pick the wattage that fits the way you play, and check the speaker size next to it, since watts alone do not describe an amp.
Compare speaker size and connections
Speaker size and outputs change what an amp can do in a setup. The Fender Rumble 500 V3 has dual 10 inch speakers and a direct XLR output, the JOYO BA-30 has a 4 inch speaker and a 3.5mm headphone jack, and the Fender Rumble 15 has an 8 inch speaker. Check the connector type in the specs table for the pick you like, and match it to the cable you already own.
Check what comes in the box
Box contents differ across these picks, so read them before you decide. The JOYO BA-30 box holds a power adapter and a power cable with an owner manual, and the Fender Rumble 15 bundle includes an instrument cable and an instructional DVD. If you already own cables, compare watts, speaker size and connections instead, and let those specs decide.
