All user reviews of 3/5 for the TC Electronic PolyTune

Polyphonic tuner pedal size, equipped with a true bypass.
I use it for 2 years now, and especially repeat concert where you can not afford to go to unplug agree!
The screen is visible. The polyphonic mode (which was a little innovation and encouraged a lot of people to buy on the spot anyway ...) can be useful to see at a glance if you are not well tuned ( although if you use its leaves, you know that we are out of tune ...), but the accuracy is not great I think.
Even in normal mode (single rope), I find it better but nothing more. In comparison my little Korg AW-2G clip and my old Seiko over 10 years of age are more accurate. Yet I plug just after the guitar at the beginning of the chain. At the same time, the system of red and green dots that light + / - next one is very far or not the note is necessarily less accurate than a good hand, even digital, which come one aim sweet spot in the center of the beach ... so Logic.
Question bypass the other hand, RAS. I find that the pedal affects my sound, this is a good point.
Luckily for me I have guitars that take good agreement, so I'm using it more for sure if it is connected ... but often I do not need.
I do not know if I will ever ... Since this choice, a mini version came out, and I read here and there it seems more accurate ... I think if I had to change I will look closely Korg Pitchblack example, which apparently has a very good reputation ...
Not a bad product per se, but not enough successful. Can do better especially when you see that knows how TC (Nova etc ...).

Bah I'm actually mixed.
Either it's great as a system, it makes a lot of time (between 2 kind song on stage for a check). It is super responsive (especially compared with my old Korg who was 18).
However ... bah how poly is false ... then it may be a poor calibration of mine. But I attach rope rope is just super. I play the 6 string, I systematically the low E which is denoted as too low, and other strings which have first a little red spot on.
If I give poly mode only, that everything is green, if I check bah mode string by string, is there any more, and this time, the guitar is wrong.
I tested with several guitar Industry Focus was telling me could be a sensitivity to micro ... same battle.

So in normal mode no problem, but poly mode ... There's clearly a concern.
It may just be mine ... I do not know. But for now I'm really disappointed ...

So here then the little beast that made me so anxious! (Note that I never had as a tuner pedal)

The heart of the matter:

Polychromatic mode, I touch the handle or not, I scratched the ropes several times in a row or one-time, with or without a pick ... not need to have perfect pitch to see if it sounds wrong I admit the way that PolyTune tells me ...

By chromatic tuning in classic cons, it pays very well except the low E, a pile of 1 / 8 th of your below ... And polychromatic, the single note that always seems well indicated, it is precisely the low E!

So I attach using 2 modes ... Not ideal but ...

Otherwise, it is downright beautiful, solid, end (next to him, the Boss seems TU3 obese and vintage die!), And replacing the battery is simple and clever ... short of that side, but good!

Mixed so I put a 8 / 10 in color mode and 2 / 10 in polychromatic since everything is fake except ... the low E.

I bought this pedal in August, have tested a month and have sold quickly.

I have lots of experience I now think in terms of format pedal tuners (I owned a Boss TU2 chronologically, a Korg DT10, a CT and a Korg Polytune Pitchblack). Reactivity level in "note for note" okay, it's in the middle (not as good as the Korg, but a little better than Boss). In "poly" is not tip top steak: it requires that the guitar pickups are perfectly tuned to the point of having a sound level of each string, and the accuracy is horrible (the 6 green lights were synonymous with guitar even false, the delta corresponding to a green line is too high).

A word more compared to a previous review: the model that I had presented no "false" in the tuning (I mean just a Mi granted on the TC was just given out a Mi ).

So yeah, to me it's still a pretty average tuner, with a mode PolyTune enough gadget (especially one with minimal musicos ear happens to detect only the strings or tune (s)).

Level readability outdoors is pretty average (like all tuners LED compared to the good old needle tuners), and poly mode on stage is pretty grim for those who have mild vision problems.

I put a 5 for the mixed impression. In the same price range the best is for me the Korg pitchblack (reactivated and excellent readability at top).
