« A genuine improvement on a Classic »Published on 09/27/12 at 15:26
The TU-12 needle tuner was an improvement in simplicity and size, but compromised in accuracy. Another downside to these tuners was they didn't have the capability to mute the guitar signal coming from the amp while the player tuned. As a result, the unpleasant sounds of a guitar being tuned could be heard by everyone.
The Boss TU-2 revolutionized stage tuning by placing the tuning solution on the guitarist's pedalboard where, with a step of the foot, mute their guitar signal, and tune the instrument utilizing a series of LED lights and Digital note readout. Pretty soon the TU-2 became standard equipment in every guitarist and bass player's pedalboard.
The TU-3 was designed to be everything players had come to love and expect from the TU-2, while addressing common complaints about the TU-2. Boss succeeded beautifully in making the classic TU-2 design even better.
The TU-3 sports a 21 LED readout, as opposed to the 12 LED readout of the TU-2, allowing a much more precise readout of microtonal deviations from the note. The display is also considerably brighter than the TU-2, allowing it to be read even on bright outdoor stages. Another improvement is response. The TU-3 tracks the signal pitch considerably faster than the TU-2. It also has a wider Vernier range than the TU-2, allowing a reference range of A436 to A445.
All of these improvements are housed in the same familiar aesthetic and functional design of the TU-2. It still sports the mute/bypass jacks, mode change, and stream/cent switch of the TU-2. With these updates, The TU-3 is destined to become the new standard in pedal tuners.
