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
- Bluetooth weight 1
Buying advice: guitar amp for small gigs
Match watts and speaker size to the gig
Output watts set how much volume an amp can produce before it breaks up. This group spans 1 watt to 7 watts: the Boss Katana Mini names 7 watts through a 4-inch speaker, while the Marshall MS-2 and the Fender Mini Tonemaster each name 1 watt. A larger speaker moves more air than a smaller one, so the Boss 4-inch speaker works harder alongside its higher wattage than the 2-inch speakers in the other picks. Compare both numbers together when you choose.
Compare power sources and controls
All three picks run on batteries, and the Marshall also accepts AC power. Controls differ more: the Boss names three amp types, Brown, Crunch and Clean, a three-band tone stack and a tape-style delay, while the Marshall names volume, tone and overdrive controls and the Fender names gain, tone and volume. If you play along with tracks, only the Boss names an aux input. List the controls you actually use, then pick the amp that names them.
Plan for silent practice and recording
The Boss adds a phones/recording output with cabinet voicing for direct recording, plus an aux input for jamming with music from a smartphone. The Fender kicks back on a metal tilt-back leg to aim the speaker where you stand. Bring fresh batteries, or use the AC option the Marshall names, since a dead amp ends the session.
