How we ranked these guitar tuners
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: acoustic guitar tuner with microphone
Pick the pickup type first
A microphone hears sound in the air, while a piezo pickup senses vibration through the body. The D'Addario tuner uses a piezo transducer, so it reads vibration rather than sound. The LIEKE and ASCENDAS picks pair a piezo pickup with a microphone, so they cover vibration sensing and microphone sound. Choose the source that matches how you play: vibration sensing for a tuner on the instrument, and a microphone when you want the air sound as well.
Match the mount to your guitar
The D'Addario tuner mounts inside the soundhole with a non-marring plastic clip, so it stays out of sight. The Homeswitch and LIEKE preamps mount onboard in the body, and the ASCENDAS preamp sits in an elongated endpin jack. The soundhole tuner clips in, while the onboard preamps install in the body or the endpin jack. Check the mount against your guitar before buying.
Check power, weight and warranty
The D'Addario tuner runs on 1 CR2 battery, and the LIEKE preamp runs on a 6F22 9V battery that is not included. The Homeswitch preamp runs battery powered, and the ASCENDAS preamp uses corded electric power. The LIEKE pickup weighs 0.3 lb and the ASCENDAS pickup weighs 0.2 lb, and the ASCENDAS pickup carries a lifetime warranty.
