The Iron tune is a high precision pedal tuner in the most compact design and can be used for guitar or bass. The advanced technology has an accuracy of +/- 1cent and reacts really fast. The semi-transparent flip-top design is different than the other Ironman pedals and clearly let the display shine through. The illuminated LED display is easy to see in any light condition. The Iron tune brings tuning precision and high sensitivity together in an incredibly small enclosure. A True Bypass circuit minimizes signal loss.
