The Fender Mustang GTX100 leads this list as Best Overall, but it runs on corded power, so it suits buskers who play near outlets. For playing away from outlets, the deciding spec is a rechargeable battery, which the flatsons FBA-20 and both Coolmusic amps list. The Coolmusic BP-40 adds 40 watts and a 5-10 hour battery for street sets.

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 busking
Pick battery power for street corners
Outlets are not guaranteed on the street, so battery power is the first filter for busking. The flatsons FBA-20, the Coolmusic 30-watt amp and the Coolmusic BP-40 each has a rechargeable battery, with 5-10 hours per charge for the BP-40. The Fender Mustang GTX100 and the Fishman Loudbox Micro run on corded power, so they suit spots near outlets instead.
Count channels if you sing and play
A singer-guitarist needs two channels, one for the guitar and one for the microphone. The Coolmusic 30-watt amp has instrument and microphone channels with reverb on the mic channel, and the Fishman Loudbox Micro has instrument and microphone channels with digital reverb and chorus. The Coolmusic BP-40 adds a third jack for keyboard. If you play instrumental only, one channel is enough.
Check weight and how it carries
You will carry the amp to the spot, so check the weight and the handle or strap before you buy. The flatsons FBA-20 weighs 1350 g and the Fishman Loudbox Micro weighs 12.3 pounds, while the Fender Mustang GTX100 weighs 28.5 pounds. The Coolmusic 30-watt amp has a strap, and the Coolmusic BP-40 has a side carry handle with a slanted cabinet that aims sound toward your ears.
Frequently asked questions
Do I need a battery-powered amp for busking?
Not always. Battery power frees you from outlets, which the flatsons and both Coolmusic amps have. If you always play near shops or cafes with outlets, a corded amp like the Fender or Fishman works.
What size amp do I need for the street?
It depends on the spot and the crowd. These picks run 20 to 40 watts except the 100-watt Fender, and the Coolmusic 30-watt amp, the Coolmusic BP-40 and the Fender each name Bluetooth for backing tracks.
Can I plug a microphone into these amps?
Some of them have it. The Coolmusic 30-watt amp, the Coolmusic BP-40 and the Fishman Loudbox Micro each has a microphone channel or jack. The Fender Mustang GTX100 and the flatsons FBA-20 are guitar-only.
How long does the battery last on these amps?
The Coolmusic 30-watt amp gives 5-8 hours after a 5-hour charge, and the Coolmusic BP-40 gives 5-10 hours. The flatsons FBA-20 has a 7.4V 3000mAh rechargeable battery.
