tc electronic Polytune 3 Noir

Great tuner with a built-in buffer at a reasonable price!

In addition to its size that saves a lot of space on a pedalboard, the tuner is quite accurate particularly in strobe mode, normal mode is also very accurate and fast.
However, when setting up my pedalboard, I ended up preferring to keep it in true-bypass mode, because it honestly sounded better and felt better under my fingers, so I think it's great to be able to turn the buffer on or off, and see what works best with your setup.
Unfortunately it is not possible to use the always on mode in true bypass, because obviously when a pedal is on it is using a buffer, so it cannot be in true bypass turned on.
I really liked the switch's soft click-free feel, and I hope there will be no problems with it in the future, given the rumors on the Internet of problems with TC Electronic switches, and the difficulty of repairing or replacing them. .
Given the tuning options, different modes, a super readable display, and a built-in buffer allied with the price, I think it's probably the best option on the market.
Plus, the Noir version makes my pedalboard look even prettier. :)
I recommend it.

The first that arrived gave up just before the 30-day return period so I was lucky to be able to send it back. This is the only thing I gave it 4/5

Build quality: really sturdy, switch button is easily engaged, very easy to see the screan
Responsiveness: shows reading very quickly, don’t have much delay. Also recognizes pretty quickly if I strum all the strings to go in polytune mode.

Accuracy: I use it most often in strobe mode, and I have done tests with tone generators to check it’s accuracy, and yeah, it is damn accurate. The polytune mode is not so much. There are times, when in polytune mode it shows everything green, but when I check it individually it is on the red(in these cases when I tested it I switched to NOT the strobe, just to make it more apples to apples comparison)

Features: the buffered mode is really nice, since using it at the beginning of the signal chain I can use it as a buffer as well. The always on is also a nice feature, when you want a little help on seeing what note you are playing when soloing, so helps learn the fretboard. The is another switch to change for different tunings which is really handy. Also if you push the main button for long it switches to drop D.

This sits at the head of my pedalboard always on buffered because I have it between a sensitive fuzz and the next pedal which is an always on overdrive. Having the option to run as always on is a nice feature to have for a quick reference during a set and still with the ability to mute should the need arise.

Having the option to switch between true bypass and buffered offers flexibility for a variety of pedalboard setups. If you want to use a buffer for a long cable run, you can; if you want true bypass across the board, you can as well.

Pros:
- Fits almost any board thanks to its small size.
- Functionally flexible.

Cons:
- (Only a minor one) It does require a power supply since batteries aren't an option.

It serves it's purpose and it serves it well and it will be staying on my board for the foreseeable future.
