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: electric tuner for acoustic guitar

Match tuning modes to your instruments

A clip-on tuner with chromatic mode tunes any note, while guitar, bass, ukulele and violin modes match the open strings of each instrument. The EX and the two Sound harbor packs cover chromatic, guitar, bass, ukulele and violin modes. The D'Addario Eclipse covers guitar, bass and ukulele, and the Histacy kit covers acoustic, electric and bass guitars and ukulele. Pick the mode set that matches the instruments you tune, and check the mode set before you buy. Chromatic mode also helps with alternate tunings.

Check the display and the clip

The EX shows tuning on a 1.97-inch full-color LCD display with a bright backlight and a large needle indicator. The D'Addario Eclipse uses a vertical full-color display with dual swivels for left-handed and right-handed players. The Sound harbor 3-pack uses a 360-degree rotatable clip and screen for a better reading angle. The EX clip rotates 360 degrees horizontally and 135 degrees vertically with soft silicone pads for the headstock. Choose the display and clip movement that lets you read the tuner from your playing position.

Choose rechargeable or replaceable batteries

The EX runs on a built-in rechargeable battery with USB-C charging and up to 10 hours of continuous use on one charge. The D'Addario Eclipse runs on 1 CR2 battery, which is included. The Sound harbor 2-pack includes 2 CR2032 batteries for its 2 tuners, and the Sound harbor 3-pack runs on 1 CR2032 battery, which is included. Rechargeable power suits daily practice without buying batteries, while a replaceable battery suits players who want a quick swap.

Frequently asked questions

Can one tuner tune guitar and ukulele?

Yes. The EX, the D'Addario Eclipse, the two Sound harbor packs and the Histacy kit all cover guitar and ukulele tuning. Pick the mode set and power source that fit the way you tune.

What does A4 calibration change on a tuner?

It changes the reference pitch the tuner measures against. The EX adjusts from 430Hz to 450Hz, and the D'Addario Eclipse adjusts from 435Hz to 450Hz. Set it to match the other instruments you play with.

Can a clip-on tuner work in a noisy room?

The EX uses a piezo vibration sensor that reads vibration from the instrument, so it tunes accurately even in noisy rooms. Clip it to the headstock and tune by vibration rather than by room sound.

What comes in the Histacy accessories kit?

The kit holds a clip-on tuner, a 3-in-1 capo, 30 picks, a leather pick pouch, an adhesive pick holder and a storage case. The picks come in thin, medium and heavy thicknesses for different playing styles.
