How we ranked these mic preamps
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: mic preamp for acoustic guitar
Match the equalizer bands to your needs
Bands are the frequency ranges an equalizer adjusts. The Jiayouy has 4 bands covering bass, middle and treble. The Fishman has 5 bands, and the LIEKE has 5 bands with volume, presence, bass, middle and treble controls. Compare the band count with the controls you will actually adjust, and pick the count that covers the ranges you shape most.
Check the output connector before you buy
The connector decides what cable the preamp uses. The Jiayouy uses a 2.5mm jack, the Fishman uses an XLR connector with a balanced output, and the LIEKE uses a 1/4 inch audio jack. Check the connector on the preamp against the input you plan to plug into, and confirm the cable type before buying.
Decide between an onboard pickup and a pedal
The Fishman is a pedal, a separate unit from the guitar. The Jiayouy and the LIEKE are pickups with pre-wired assembly. The LIEKE installs in the body of a standard acoustic guitar. A pedal suits a player who wants foot control, while an onboard pickup suits a player who wants the controls on the guitar.
