First of all, long time no see for me and this forum
Regarding the topic, I was in a need of a tuner in pedal form for live use, so I looked a bit around. Turns out Digitech has released this new pedal with chromatic and strobe modes a few months ago, sort of their take on TC Electronic's Polytune, but a bit sturdier and IMO with better display options. Its accuracy is plus/minus 1cent.

Drawback for me would be that it only has a few tuning options in the polytune mode (but it does have an usb input, which is supposed to be used for possible future custom tunings updates), and that it's meant for use with a 6 string guitar. But no biggie, 'cause I could use the chromatic mode for the 7th string. Another really cool feature is that the moment you engaged it, it instantly mutes your signal, which is really cool for live use. Oh, and apparently it's a true bypass.
Anyways, I'll probably end up buying it.
They also has HT-2, sort of the chromatic-only version of HT-6, which is also supposed to be good, so you might also want to check that one out.
