TC Electronic POLYTUNE 3 MINI Tiny Polyphonic Tuner with Multiple Tuning Modes and Built-In BONAFIDE BUFFER, White

This thing is amazing. Never have I been excited by a guitar tuner until now. I love it and I haven't even figured out all of the various options this thing offers.The standard tuning mode and the polytune feature are nice, but I generally use it only on the chromatic/strobe mode. I've heard it can also tune to 432hz and do other tricks as well. I tune to either E standard or Eb standard and it works great for that. I really love the strobe mode for the accuracy. I use the "bars" in strobe mode to get it close and then can use the strobe lines to get it as close to perfect as my hardware can manage.I also appreciate that it stays in my chosen mode when I unplug the board and go to a gig. Pressing the little button by the power input can be fiddly while on the board, but I only need to press it when I'm toying with it at home. It's always gig-ready on the last settings I used.The foot switch is great. There is no click. It just moves up and down smoothly, and a light tap turns it on/off. Same switch as my mini Ditto looper by TC.I use the buffer for now. I have flipped the buffer switch a few times, but can't tell much difference in the sound when the tuner is off one way or the other. Maybe it will be more apparent to me in time. I use about 30ft of cable in my rig altogether, so I like the idea of a buffer at the start of the board. I have not used the "always on" mode.I started with a heavy, ancient tuning pedal which looked similar to a boss pedal. It was awesomely accurate, but half broken and stuck in always-on mode, so I couldn't mute my sound while tuning. I upgraded to a donner deluxe mini tuning pedal, which is a nice size, but turned out to not be very accurate at all. It would get me close enough to be able to play, but I was never totally happy with my tuning with that pedal.So eventually, I did my research and decided this was the best option for a mini tuner with guaranteed accuracy. And I was right. This guy almost never shows a string as being properly in tune and it's very easy to jump past that marking showing you as in tune. That is great in my opinion, as it means it is accurate. And I can absolutely hear a difference. My chords sparkle again and I'm in love with the sounds I get from this rig now.The display is also nice and bright and easy to read from a distance.My guitarist friends freak out when I let them tune my guitar and show them all the stuff this thing can do. It really is awesome and I'm glad I made the investment.If you are a bedroom player, it may not be worth it, but if you are recording or playing live shows often, I absolutely recommend this tuner. It is about as good as any tuner can get and also in a tiny package. These are slowly replacing the old trusty Boss tuners as the industry standard.This tuner is the most expensive pedal on my pedalboard and I am totally okay with that. I should have bought one of these years ago.

Absolutely great tuner pedal for cost! Super simple functionality and nearly zero delay.. this pedal does not affect your sound quality at all and the LED display is super bright. These have a bonafide buffer built in. Seriously under valued tuner.

Love it.TinyNeeds an external power supply as no battery.Tunes greatAccurateLove the spinning tune modeIt spins slower until it’s in tune and spinning stopsChronographic tuner?Anyway I purchased it for that and it’s accurate enough to intimate guitar

Awesome pedal.Super fast response time.Loads of flexible functionality.Love that it has an in-built buffer.Love that you can turn the screen on all the time, or part of the time.Love that you can adjust the "poly" tune part of it to register drop D, plus a number of chromatic tuning positions (helpful for de-tuning to e flat -- hate it when bands do that!) or when using a capo. When in those modes, you can hit all the open strings and the polytune will track which are in-tune and which are out of tune.While I will hit the button to tune in silence when starting my play session, I find that the "always on" screen is really helpful to get a quick tune-up mid-session.I find I am checking whether I am in-tune way more often, since the readout is always there. This makes me sound instantly better. I will also sometimes sneak a peak at the device when strumming a chord - using the poly mode you can see which open strings are in tune or not. And it gives you a quick check - even mid song - regarding whether you need to quickly turn the tuning knob up a tick to compensate for a wicked string bend you did on that last solo....

Fabulous Tuner with a Bright and Accurate Display.However - the unit MUST be powered externally as it is Sealed and does NOT take a 9v Battery.My sole purpose was a portable Tuner I could use for rehearsal / open mic - I now need an external battery.The Product Description clearly says: Power Source - Battery Powered.As well as the Compare with Similar Items listing also: Power Source - Battery Powered.

This ‘smaller’ tuner works great! Very accurate and easy to use.

Very compact, fast, accurate. The boys get is legit 🤣

Easy to see color coded display. I just use it for simple on stage tuning adjustments for my 12 and 6 string acoustic/electrics. Its only four because I found the instructions for the more complicated functions are not easy to understand.
