Boss TU-3 Electric Guitar Tuner Pedal

The Boss TU-3 Electric Guitar Tuner is a chromatic tuner encased in a hard stompbox body. A mighty companion for gigging.

The Boss TU-3: Raising the standard of Electric Guitar Tuners!
The most popular stage tuner, the Boss TU-2 has evolved in to the Boss TU-3. It has more lights, more accuracy and faster response!

This Boss tuner pedal is housed in the same tank-tough stompbox body as it's brethren (which it can supply power up to 7 of, if you link them together).

It has a High-brightness mode for when you are playing outdoors, an Accu-Pitch Sign to highlight when tuning is complete and Note Name display.

It supports 7-String Guitars, 6-String Basses and drop down tuning up to six semitones below standard pitch.

When you're connected using the Output connector, the pedal will mute the sound whilst you tune silently (between songs for example). If you choose the bypass output however, you will continue to be heard and tune at the same time. You can also use the tuner to split the signal up if you wish to take it to different outputs.

If you want the best Tuner pedal available then choose the Boss TU-3 Tuner.
