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

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....

I was tired of using tuners that were built into other devices I have. They're OK to use, but don't have the fidelity or accuracy I wanted. This tuner is awesome. It has a really cool feature where, if you hit all 6 strings, it'll show you where each one is, sharp, in-tune, or flat. Really easy to see. It does need a 9V power adapter to work... to make sure you get one of those too.

Works very well. I really like the always on feature. Keep it on mounted on top of the amp so to reduce pedal board clutter.

Este pedal es una maravilla, tiene mucha precisión para la afinación, trae un buffer y es muy pequeño, ocupa poco espacio en mi Pedalboard. La verdad que este pedal es excelente!

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.

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

Great space saver and amazing tuner. Bonafide buffer is a plus.

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.
