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
- Headphone output weight 1

Buying advice: guitar amp for bass
Compare watts across the picks
Watts set the ceiling. The JOYO gives 10 watts, the Orange 25 watts, the Rumble 40 gives 40 watts and the Rumble 100 gives 100 watts with the Most Power label. Speaker size moves with watts: 5 inches on the JOYO, 8 inches on the Orange, 10 inches on the Rumble 40 and 12 inches on the Rumble 100. More watts and a bigger speaker mean more headroom. Pick the watts that fit your playing situation.
Check practice features
Practice features decide the quiet hours. The Orange has a Cabsim-loaded headphone output and an aux in; the JOYO has a headphone jack and an aux in for songs from a phone. The Orange adds a chromatic tuner, and the JOYO runs on batteries for up to 3 hours outdoors. The Rumble 100 and Rumble 40 add overdrive circuits and contour controls. Pick the headphone output for silent practice; pick overdrive for distorted sounds.
Compare weight and warranty
Weight decides the carry. The JOYO weighs 2.9 lb, the Orange 20.5 lb, the Rumble 40 20.9 lb and the Rumble 100 23.3 lb. For warranty, the Orange carries 1 year and the JOYO carries 1 year, while both Fenders carry 2 years. A lighter amp moves easier; a longer warranty covers more time. Pick the weight and term that fit the gig.
