The TC Electronic Polytune is an exciting (at least, it is to us) new pedal that is set to revolutionize the way guitarists tune their instruments.
Unlike traditional guitar tuners, which required the user to sound one string at a time, this piece of technical wizardry only needs one strum. It can then seperate the frequencies of each string and indicate which ones
are out of tune and by how much.
