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 for gigging
Match watts to how you play out
Watts decide clean headroom before the amp distorts. The Spark LIVE lists 150 watts, the Mustang GTX100 lists 100 watts, the Katana-50 lists 50 watts, and the Acoustasonic 40 and Coolmusic BP40 each list 40 watts. In this list the higher-watt amps weigh more: the Mustang GTX100 weighs 28.5 pounds while the Acoustasonic 40 weighs 10 pounds.
Check the outputs that reach the PA
A DI-OUT or XLR line output sends your sound to the mixing console. The Mustang GTX100 lists stereo XLR line outputs, the Coolmusic BP40 lists a DI-OUT port, and the Spark LIVE lists two line level outs. Compare the outputs each amp names against how you plan to reach the PA.
Decide if you need battery power
Battery power frees you from outlets. The Coolmusic BP40 is battery powered with 5 to 10 hours of working time, and the Spark LIVE offers an optional rechargeable battery rated up to 8 hours. The Mustang GTX100, Katana-50 and Acoustasonic 40 are corded electric. If every gig has wall power nearby, skip the battery and compare watts, outputs and weight instead.
