Chromatic Floor tuner

Latest User Reviews
A Must
This tuner is all you need. The chromatic tuner works very well, and the lights are visible from pretty far away, even in the dark. If you need a tuner pedal, this one is a good choice!
CLASSIC BOSS TUNER
It's a no brainer buy
Super accurate
I needed a tuner for my bass guitar. After evaluating a few tuners, I settled for this one based on the positive reviews. I'm quite happy so far!
Great tuner - bit expensive
I have a lot of other Boss gear so am used to stuff being a little pricey. This is still less than the WAZA Craft version by a lot so is better value than that but unless you love the Boss aluminium case design, would not recommend over cheaper alternatives. For me the biggest selling point is the sound cut-off while tuning.
Premium tuner
The tuner is just amazing, it has a great precision with many modes to choose from. The pedal has a premium feel and look and I would recommend it to everyone!
This is the only one you need.
I did spend a while contemplating buying a different tuner…but why? Boss pedals are so solid and reliable, it should last a lifetime.
Very intuitive and easy to use.
Easy to use tuner
Works as it should and will probably never break.
Heavy Duty and Reliable Floor Tuner
I already have a Rockboard Stage Tuner ST-01 V2 but found this to be unreliable and too slow to pick up the input from the guitar. I was therefore looking for a more 'heavy duty' and reliable tuner that would work on stage.
I took a look at various options but I like the two Boss pedals that I already have as they are solid pieces of kit, plus a friend already had a Boss TU-3 and he recommended it.
It is great. It worked as as soon as I took it out of the box, is quick and reliable with a number of useful settings and integrates well with the other pedals. It is a quality build and clearly robust enough to last a long time.
If you are looking for floor tuner under 100 euros then this is the one for you.
Classic and simple
This is simply my favorite tuner pedal of all times. The design is classic and it’s built like a stone.
Very helpful tuner.
It is just amazing and solid product.
