After a 12 year production span, the TU-2 has been replaced by the TU-3. The most significant changes is that the accuracy has been improved to +/-1% and the display now features a 21 segment LED meter where the TU-2 had 11 LEDs. The mode button lets the user switch between Chromatic, guitar and bass as well as flat modes for each of the three main modes. The flat mode allows the user tune one to six semi tones lower.
