Excellent tuner
Patrick M, 29.10.2015
I've tried rackmount tuners and a couple of other cheaper boxes, but there's no escaping this simply rules the roost.

Excellent accuracy and note acquisition, even for notes on a bass too low to be deemed safe for your trousers.Feels durable and safe to give a good whacking with your foot when using the mute function. Doesn't seem to drain battery life either. My only gripe is that for a top of the range tuner, at quite a few pennies, you're buying literally just a box. No power supply, no case. That's just the way with Boss; but it is the only thing that really holds it back.

For the tl;dr...

Pros:
Durable as mad
Plenty of functionality without being confusing
Very accurate
Very fast to acquire notes
Decent battery life

Cons
Nothing but the tuner is supplied

I have already known this tuner, I have read and heard just good things about it. I use it on my pedalboard. The range of the display is enough, I have good eyes to see it. One of my guitar is tuned A drop, and there is no problem with it, the tuner can catch it easily. Previously I use a Behringer rack tuner, but it was not as much sensitive as this Boss pedal is. So, the legends are true, this is a great tuner!
