Great tuner, a bit confusing at first
A. j M. 08.05.2020
This is THE tuner pedal out there. Don't look any further ever, and stop asking reddit how it compares to Boss or D'addario (two brands that I otherwise really appreciate) - it doesn't. This is in its own ballpark.
I mean you get:
- True bypass if that's what you want
- An excellent buffer if you prefer (great thing to put right at the top of your chain if you have passive pickups)
- 3 different view settings (I use the classic one)
- A 9V output to daisy chain another pedal (because who wants their tuner to take a spot on their juice box, amaright?)
- Infinite tuning options, and you can set up your favorites
- Send in different settings to the pedal from your phone through the pickups (you read that right)
- Optionnal Always on display (so that you can pretend to know your fretboard by heart)
- Polyphonic tuner is a great thing
- Killswitch
- Great build quality

I must forget something, but as you see, I do believe it's a no brainer, I don't see any reason to get any other tuner at that price point on the market at the moment.

The only down side is that it may have too much options to start with and can be overwhelming at first if you want to use the whole alternate tuning thing. But nothing an hour with the manual and many tutorials online will not get rid of :). If you only need normal tuning - it's really just plug and play, so you won't have that issue at all!

Disgusted with the lack of Quality Control / Customer Service
vegan pete 14.05.2019
I bought a TC electronic polytune 3. It came with no access to the internal dip switches due to a manufacturing error. Thomann advised that they were all like that, not true, also advised that taking it apart wouldnt invalidate the warranty, also untrue as confirmed by the manufacturer. Only recourse was to send it back to the manufacturer under warranty, would not give a replacement, leaving me without a tuner. Unacceptable for Thomann to provide such bad customer service, and TC Electronic to provide such bad quality checking / manufacturing.

Somewhat disappointed
Rihtercicimoji 27.10.2025
This pedal is simple. It helps you tune your instrument and does that well.
It has many cool features like the additional power supply output, true bypass and buffered, and more.


I'm having two issues with it:

The switch
It's very low quality and easy to press down.
Since i have large shoes, sometimes I press the nearby area and accidentally engage the pedal which then becomes a fancy mute switch.
This is an expensive pedal (if you look at it as just a tuner pedal) with a cheap switch and I don't think it would be a much larger production cost if they just put a quality switch.

Polytuning
It's innovative and I'm amazed how people can do something like this.
That being said, I don't think it's there yet.
Sometimes when i try to play single notes when in a loud environment (rehearsal/gig) it registers as if I want to tune all the strings at the same time.
This makes the process a bit difficult and time consuming in some areas.
For me the perfect fix would be if there was a way to disengage the Polytune functionality all together and make it an exclusively single note tuner. Though I see why that might make no sense since it's the whole shtick of the pedal.



All in all, I probably wouldn't buy the pedal again nor recommend it.
It's a bit pricey for (in my opinion) an imperfect product.
I doubt I will go out of my way to sell it, but the idea of exchanging it for a Boss tuner isn't off the table.

Excellent tuner pedal
7 Dying Trees 20.01.2022
Great tuner pedal, has 2 9v adaptor outs to power 2 other pedals which is really useful.

Clear display, nicely lit up, easy to see.

Quality construction

Handles low tunings (down to a low E on an 8 string) well too.

And, it dosn't cost the earth, so it is awesome value for money. Am think of getting another one just for home use.
