TU-3 : Boss TU-3

Brilliant little pedal, very easy to use, better than my previous TU-2.

Adjustable brightness means you can use in various conditions.

I keep it first in my pedal chain, two outputs mean it can be used it can be used straight through or in bypass, I keep it in bypass and use it as a kill switch.

If you purchase the optional daisy chain lead (PCS-20A) it can power a number of additional pedals.

The right hand button is the mode button, you can toggle between 6 modes.

The modes allow you to tune chromatically, choose bass or guitar and includes the ability to tune flat by semitones. This tuner also works with 7-string guitars and 6-string basses.

I have used it constantly for two years now and no problems at all, couldn't be happier with this tuner.
