This would be one of the most expensive pedals I've bought (I buy all used stuff and don't own a klon haha) AND IT'S A TUNER. Basically, I'm deciding between the Polytune, Pitchblack, and Turbo Tuner. I feel like these will be much easier to see than the TU-2. I can get the other two much cheaper used than a new Turbo Tuner since everyone loves theirs and don't want to sell which should speak enough. Is there really THAT much of a diffence in a few cents of accuracy? Will it be noticeable? Sell it to me.
