When the TC Electronic PolyTune came out, it blew up the tuner pedal world. The polytune ability (meaning you can strum all 6 strings and it will show you which strings are flat/sharp) was incredibly innovative. You can strike an individual string and it will go into standard tuning mode. Personally, the polytune is the nicest feature. When you’re playing and you hear something *off* and want to quickly correct the out-of-tune string, it’s a snap to activate the tuner, give it a strum and ID the culprit, vs going down every string to see if the string is out or not.
This year’s Winter NAMM, TC Electronic took the PolyTune one step further by making it smaller! They developed the TC Electronic PolyTune Mini. Ultra small enclosure with all the same features as the original PolyTune. They’ve improved the software to picking up additional tunings, and when I say this, I’m referring to the polytune mode. No matter what tuning you use, you can use the standard individual string tuning mode.
UPDATE – It has been pointed out that the polytune has issues with basses. The chromatic function works fine with basses, just the polytune mode has problems.
