Angry Boss tuners against the pedal format (too expensive for my budget), I bought it on AF at a very reasonable price (about 45-50 euros fdpin).

This 4 months ago.

For use in rehearsals, cushy studio, the output bypass: no pb. Note grip without much trouble, visibility is perfect notes.
I deplore the taking of power supply area on the side (-1).
Having forgotten my garland once or twice, I realized it was running on battery, and consumes very little a priori.
By mistake, I plugged in once the non-bypass output: loud noise unbearable parasite (-1), unless this was due to a weakening of the cell, in which case I was wrong: it uses the well battery!

Finally, the reason for this opinion and my biggest disappointment was dropping right in concert
The pedal part, which is pressed to engage the tuner, is black plastic all rotten. A fall had the deep and open-tuning the beast decided to show me his guts rather than fulfill its function ... (-5)
Even without violence (though I do rock-punk, I take everything very care of my stuff)

Impossible to repair (-3) over warranty.

Rescued by my little Boss (TU-80), I think I'm finally well be forced to turn to the dinosaurs (Boss, Korg, etc. ..)

So I recommend this pedal, very highly!
-1 -1 -5 -3 = 0
Sorry.
