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

One of the Best Tuners

The Fordster 07.01.2025

By far a brilliant tuner. They are so good, that I bought this one for my Bass pedalboard. I used to steal the one from my guitar rig when I was recording bass, but now with this one I do not need to. It will also pick up a low B string on a bass, so is totally worth it.
I am thinking of another one for just having around.
You can use it as a switch on tuner, where the audio is muted or you can use the bypass and still hear your sound.
I just use the Chromatic setting, but you can use it for various lower “standard” tuning.
The lights are plenty bright to use on a dark stage and still see exactly what you are doing, and the raised part of the screen area can be seen from a good distance away.
If you need a tuner, buy this one. If you don’t need a tuner, buy this one anyway.

Must have pedal in S.C

Theofanhs Siderhs 07.02.2022

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)
