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 100
Match watts to your practice space
Watts decide how loud an amp gets. The MS2 lists 1 watt, the LEKATO lists 5 watts, the MG10G lists 10 watts and the GLARRY lists 20 watts. For bedroom practice, 1 to 5 watts is enough. If you jam with others, the 20-watt GLARRY gives more headroom before the sound breaks up.
Check the power source first
The LEKATO has a built-in rechargeable battery that runs up to 6 hours, and the MS2 runs on a 9V battery or AC. The GLARRY and MG10G are corded electric. If you practice where there is no outlet, pick a battery-powered amp. If you always play near a wall socket, corded is fine.
Look at speaker size and weight
Speakers here range from 2 inches on the MS2 to 8 inches on the LEKATO. Larger speakers move more air for a fuller sound. Weight ranges from 0.8 lb on the MS2 to 10.5 lb on the MG10G. If you carry the amp to lessons, the lighter ones travel easier.
