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

A wise investment

26.04.2016
use: studio and live guitar work

pros:
-very solid build quality
-extra bright mode is great for playing outdoors on a sunny day
-very accurate and consistent
-easy to use and it works with both guitar and bass
-does not impact/colour guitar tone like some cheap tuners
-makes tuning a much faster process

cons:
-cannot tune acoustic guitars which have no pick-ups as there is no built in mic

overall:
Even though there are cheaper tuners available at much lower prices I wholeheartedly recommend you buy this tuner. Cheap tuners tend to be fiddly and unreliable (I have owned many in the past), this is built like a tank and I expect it to last for years.
A wise investment in my opinion.
