A while ago I posted a video of the prototype of this innovative guitar tuner
now this is the finished product by TCelectronic:
you can find the product info on the TCelectronic page here:
This is innovative as you can see you can tune all the string at once. Not only that, it switches between the ‘old style’ tuning one string at the time and the new mode automatically…and it is true bypass.

In the UK this is £75 on-line for now…I am sure it will come down in price once all the brands will align to this new technology.
