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: tuner pedal

Check true bypass before you buy

True bypass means the pedal passes the signal untouched when off. The KLIQ, the MEDIORAYS, the flatsons, and the Rowin offer true bypass switching. Compare the bypass type on the pick before choosing, and match it to the pedalboard setup planned.

Compare tuning range and calibration

Tuning range decides which notes the pedal covers. The KLIQ covers A0 to C8 with calibration from 420 to 459Hz, and the flatsons covers A0 to C8 with A4 calibration from 435 to 445Hz. The MEDIORAYS and the Rowin offer 1 cent accuracy for tuning. Pick the range and calibration that match the tunings planned.

Look at power and display options

Power and display decide how the pedal fits a pedalboard setup. The KLIQ needs a 9V power supply, the MEDIORAYS runs on DC 9V or USB 5V, and the flatsons runs on a 9V DC adapter. The KLIQ shows needle and strobe modes, the flatsons shows a color display, and the BOSS shows a 21-segment LED meter. Check power and display on the pick before choosing.

The KLIQ needs a 9V power supply, the MEDIORAYS runs on DC 9V or USB 5V, and the flatsons runs on a 9V DC adapter. The Rowin notes a DC 9V adapter is not included, so check the adapter before a session.
