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
