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

Buying advice: guitar amp under 150
Match watts and speaker to your use
Watts and speaker size set how much amp you carry. The Coolmusic gives 30 watts through a 6.5-inch speaker, the flatsons, Orange and Fender give 20 watts each, and the Marshall gives 1 watt. Speaker sizes run from 2 inches on the Marshall to 8 inches on the Orange, with 3 inches on the flatsons, 6 inches on the Fender and 6.5 inches on the Coolmusic. If you carry the amp daily, the lighter end of this list is easier to move.
Compare warranty terms before you buy
The warranty term is the clearest difference on paper. The Coolmusic carries a 3-year warranty, the flatsons and the Fender a 2-year warranty each, the Marshall a 1-year warranty and the Orange a 1 year warranty. A longer term gives you more time to ask the maker for help if the amp has a defect. Read what the term covers in the product page before you decide.
Decide how you will power it
The flatsons has a built-in 7.4V 3000mAh rechargeable battery and the Coolmusic runs up to 5-8 hours on a charge, so both play away from an outlet. The Marshall runs on a 9V battery or AC power. The Orange runs on corded electric power, which suits playing near an outlet.
