The JOYO JF-326 Irontune is a compact pedal tuner from Joyo built for guitar or bass. JOYO describes it as a high precision pedal tuner in the most compact design, with an accuracy of +/- 1 cent and a fast response1. It is part of JOYO's Ironman line of mini pedals, and its semi-transparent flip-top is different from the other Ironman pedals: it lets the display shine through, so you can read the tuner without flipping the lid open1.
Size, weight and power
The Irontune is a genuinely small pedal, weighing 220 g1. That footprint fits a crowded pedalboard where a full-size tuner would not, and the weight keeps it planted underfoot. It runs on a DC 9V adapter and draws 90 mA of running current1. There is no battery option on the spec sheet, so a power supply is part of the plan from day one.
At 90 mA, the Irontune draws more current than many mini pedals. Check the rating on the output of your power supply you plan to use; a low-current tap may not carry it.
Tuning performance
JOYO specifies an accuracy of +/- 1 cent and says the advanced technology reacts really fast1. The detection range runs from 12 Hz up to 4186 Hz (C8)1, which covers everything from a bass's lowest string to a guitar's highest fret, so the same pedal works on either instrument.
Where it sits among pedal tuners
The Irontune competes in the crowded mini tuner field alongside pedals like the MOOER Baby Tuner, the Korg Pitchblack Mini (Black) and the TC Electronic Polytune Mini. Its +/- 1 cent accuracy claim and true bypass put it in line with what players expect from a dedicated stompbox tuner; see the full range on the Tuner Pedals page. JOYO also makes the larger JOYO JF-18R Power Tune, which combines tuning with power supply duties1.

Questions
Is the JOYO JF-326 Irontune true bypass?
Yes. JOYO says the Irontune uses a True Bypass circuit that minimizes signal loss, so when the pedal is off your guitar's signal passes through without the tuner's circuitry loading it. That matters on a pedalboard where the tuner sits early in the chain and would otherwise always be in the signal path.
What power supply does the JOYO Irontune need?
The Irontune runs on a DC 9V adapter, according to JOYO's product page. There is no battery option listed, so plan on a pedalboard power supply or a one-spot style adapter with the correct polarity. At 90 mA of running current it is worth a proper supply rather than a daisy chain shared with several other pedals.
Can the JOYO Irontune tune a bass?
Yes. JOYO describes the Irontune as a high precision pedal tuner that can be used for guitar or bass. Its detection range runs from 12 Hz up to 4186 Hz (C8), which covers a bass's low strings as well as a guitar's full range, so one pedal can serve both instruments.
How accurate is the JOYO JF-326 Irontune?
JOYO states an accuracy of +/- 1 cent, which it attributes to advanced technology, and says the tuner reacts really fast. One cent is a fine margin of error for a pedal tuner at this size and price class, tight enough for stage tuning and most studio work.
How much current does the JOYO Irontune draw?
JOYO lists the running current at 90 mA. That is more than some mini tuners draw, so when budgeting the outputs of a pedalboard power supply, give the Irontune an output rated for at least 90 mA rather than a low-current 50 mA tap.
