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.

Buying advice: guitar amp for live gigs
Match the wattage to the gig
The Spark LIVE runs 150 watts, the BOSS runs 60 watts, and the JOYO, COOLMUSIC and Fender each run 40 watts. Higher wattage means a louder maximum output. Check how you will amplify the amp at the gig, then match the wattage to that plan.
Check the mic channel and DI output
The JOYO, COOLMUSIC, Fender and BOSS each have a mic channel alongside the guitar channel. The COOLMUSIC has a DI-OUT port for linking external mixing consoles, and the BOSS has an XLR DI jack. If you sing, a mic channel saves you a separate vocal amp. If the gig runs a PA, a DI output feeds it directly.
Decide how you will power it
The JOYO and COOLMUSIC run on built-in rechargeable batteries for 6 and 5-10 hours. The Spark LIVE offers an optional rechargeable battery for up to 8 hours. The Fender and BOSS are corded electric. If you play where outlets are scarce, battery power wins.
