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.


Excellent tuner pedal

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.


Must have

The most used tuner. Simply the best, it displays clearly the tune of your strings. It's also very beginner-friendly, one simply can't make a mistake tuning his strings. Being very compact It's very easy to find space in your board (a tuner should be the first pedal you buy but this is another matter). Imo a really valuable function of this tuner is the buffer, very useful if you have many pedals. Like the title says, a must have!
