General
The Boss TU-3 is a chromatic tuning device in a sturdy pedal body, also known as a stage tuner. The TU-3 features a 21-segment LED meter with a High-Brightness mode that enables you to tune up accurately even in the harshest glare.
Boss TU-3 details
This tuner offers a choice between chromatic or bass/guitar tuning mode. Due to the Accu-Pitch function you are able to tune up pitch perfectly. The TU-3 displays note names, even for seven-string guitars and 6-string basses. The Flat-Tuning mode supports up to six half-tone steps. When the pedal is activated, the outgoing signal is automatically muted. Futhermore, with the use of the optional PSA230 and parallel cords, the TU-3 can supply power to up to seven extra Boss effect pedals.

I dont normally leave reviews but Ill give praise where praise is due.
The BOSS TI3 is a fantastic quality pedal that has a lovely feel and build quality to it. I am fairly new to BOSS pedals, having recently acquired a older BOSS OC-2 as much first, I was introduced to the manufacturers build quality and feel. Also the TU3 has a 5 year warranty from BOSS, giving you some reassurance that they think their products have some longevity.
That operation of the pedal is very smooth and its simple to use. However there is the ability to alter some parameters if the user wants to delve a little deeper. I play a 5 string electric bass guitar and the tuner is perfectly happy with the low B.
The action of the foot switch is very quiet and not clunky in any way (BOSS use an electronic switch rather than a mechanical one used by a lot of other manufacturers, a feature that I particularly admire).
One point I was not sure about was the size of the display readout, as my now spare tuner has a larger display. However in use the TU3 is nice and bright and clearly readable so my doubts were unfounded.
All in all a great pedal, and from BAX the most competitive price (with free shipping

Een echte boss TU-3 chromatic tuneer, wie had ooit gedacht dat je zo'n prachtpareltje mocht bezitten. Nooit meer gekloot tijdens repetities met ssssst stil zijn ik probeer te stemmen. Of die klote apps gebruiken die er toch altijd minimaal 2c naast zitten.
Neee met deze boss chromatic tuner speel je zo in tune dat zelfs vogelzang vals begint te klinken. En laten we eerlijk wezen, die beestjes zijn toonvaster dan Judith van op de hoek die iets te hard onder de douche zingt. Judith als je dit leest, misschien is dit product ook wel wat voor jou!

Deze tuner werd snel geleverd door Bax. Ik heb meerdere tuners, maar deze steekt met kop en schouder boven de rest uit. Perfect te gebruiken in een pedalboard. Ook heeft deze tuner veel mogelijkheden. Al met al een AANRADER.
