How we ranked these guitar tuners

Every pick ranks in Amazon's best-seller list for its category and has 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: guitar tuner for accuracy

Compare accuracy figures first

Accuracy is the deciding spec here, and the figures are easy to compare. The RuiJOTWAT pick tuner gives real-time pitch monitoring with color-coded indicators. When accuracy figures match, compare the tuner type, the display and the power source next.

Match the tuner type to the job

Pedal tuners sit in a signal chain and mute the output while tuning. The VOVENTO pedal mutes the output with the footswitch and routes the signal around the tuning circuit with true bypass, and the MEDIORAYS pedal mutes the output during calibration with true bypass. Clip-on tuners sense vibration through the instrument: the SIREN uses vibration sensing with a 360° rotating clip, and the FEYANOR uses vibration pickup with 6 modes. The RuiJOTWAT pick tuner works while you play, as a pick with a tuner built in.

Check power before you buy

Power decides whether the tuner is ready when you are. The SIREN runs on a built-in rechargeable lithium battery with up to 8 hours of playing time and recharges in 30–60 minutes with the included USB-C cable. The VOVENTO needs an external 9V DC center-negative power supply, and the adapter is not included. The MEDIORAYS runs on DC 9V adapters or USB 5V power, and the FEYANOR runs on a pre-installed 3V CR2032 lithium coin battery.

Frequently asked questions

What does ±1 cent accuracy mean for a guitar tuner?

It means the tuner reads pitch to within 1 cent of the target note. The VOVENTO, SIREN, MEDIORAYS and FEYANOR tuners give ±1 cent accuracy, so they share the same accuracy figure.

Are pedal tuners better than clip-on tuners?

Pedal tuners mute the output while tuning and sit in the signal chain, while clip-on tuners sense vibration through the instrument. The VOVENTO and MEDIORAYS pedals give true bypass, and the SIREN and FEYANOR clip-ons give ±1 cent accuracy with vibration sensing.

Do I need a power adapter for a tuner pedal?

The VOVENTO needs an external 9V DC center-negative power supply, and the adapter is not included. The MEDIORAYS runs on DC 9V adapters or USB 5V power, and its adapter is not included either. The SIREN recharges over USB-C instead.

Which tuner works for bass as well as guitar?

The VOVENTO tunes electric guitar and bass, the SIREN covers guitar, bass, violin and ukulele, and the MEDIORAYS supports electric guitars, electric basses and ukuleles. The FEYANOR covers guitar, bass, violin and ukulele with 6 modes.
