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

Must have pedal in S.C

I stopped having extra tuners or mobile applications in my bags, I placed the specific pedal in my signal chain and I can just do everything ... whoever has the pedal understands ... in terms of durability and quality is not discussed

Best item in my boss pedal-baord. In live performances, I only take a rapid look to tune the guitar. If you purchase this item, don't forget to switch off other pedals connected an plce it first of the line (in my opinion)
