TC Electronic PolyTune 3 Ultra-Compact Tuner Pedal with Polyphonic Tuning, Built-In Buffer, and Bright LED Display

Have wanted one of these for ages, and really glad I splurged. The polyphonic tuning is a really nice feature, but - as you'd expect - it's your rough guide and it takes a bit of getting used to. The display is super clear and it's one of those devices that just becomes super intuitive to use very quickly. Be careful you don't put it in Drop D tuning by mistake and then wonder why the bass E readout is wrong!

Best tuner I've ever owned, just having the range of options like having the display always on is really useful at times. And tuning is so fast. I didn't know I needed all these features.

Amazing quality tuner, very accurate.Easy to use and is a small profile on the pedal board.

The market is a wash with loads and loads of pedals for tunning, This one for me is the best. The display is nice and clear and bright too.

Perfect. Good quality, nice display.

Great tuner & more. After using it for several months now, it is far superior to clip-on tuners that keep breaking. Should have invested in one years ago and saved myself the trouble and money. Having the different tuning/display options is also useful.

You pick up the guitar and it sounds in tune. Then you switch on the polytune and realise a couple of strings are slightly out. Really pleased with this.

I like the polyphonic tuning function and this seems to work quite well for quickly zoning in on put of tune strings on a 5 string bass. I prefer the needle setting to the strobe as it can be difficult to see which way the strobe is going once it gets nearer to being in tune.I use it with the buffer on and can't say I notice any difference between using it with or without. It's a nice feature to be able to switch it on or off though.
