The JOYO Irontune is a very precise guitar tuner with a compact design that works great with both electric and bass guitars. Advanced technology allows you to achieve the highest precision, which oscillates around +/- 1 percent, and allows for a really fast reaction of the tuner. The semi-transparent top cover is designed differently than the rest of the Ironman series, and clearly shows the LED display below it that imitates the pointer. The LED display is easy to read in all lighting conditions. Irontune presents precision that goes hand in hand with incredibly high sensitivity. True bypass switch minimizes signal dropouts.

The Ironman series is characterized by small size, perfect workmanship and a specially designed movable potentiometer cover that protects the potentiometers from damage and unwanted setting changes.
The appearance of each of the effects of the Ironman series is a conscious design modeled on the head of one of the most recognizable super heroes from the comic books of a well-known American publishing house. Like the Ironman armor, the housing is made of a thick die-cast metal layer, which contributes to the durability of the Ironman series JOYO effects. Each effect from the Ironman series has a true bypass switch, which significantly affects the sound quality with a large number of combined effects on the pedalboard. The potentiometer knobs in the Ironman series are made of the highest quality plastic, resistant to mechanical damage and are distinguished by a well-thought-out color and size of the knobs, which results in excellent visibility of the sound settings when using the effect. Special LEDs, located on the metal housing next to the knobs of the potentiometers, inform the user about the activation of the effect, and when the cover is closed, they illuminate the inscription JOYO. Each of the JOYO Ironman pedals offers the highest quality of sound, thanks to the highest quality miniature electronic components contained in such a small housing. It is enough to take any effect from the Ironman series to see how perfectly these effects are made, and connecting these effects to the amplifier will prove that the production of JOYO in the Far East does not differ from the highest world standards, and in some moments even exceeds them.
