Some scratches but works perfect.The TC Electronic PolyTune 2 polyphonic tuner pedal takes the tedious but necessary process of tuning your axe to a whole new level. In polyphonic mode, this smart piece of hardware allows you to check tuning on all your strings at once with its easy-to-read LED display. If you prefer going one string at a time, this pedal also has a more traditional monophonic mode. This pedal provides +/- 0.5-cent tuning accuracy, with reference pitch from A = 435 to 445 Hz. If you like to use alternate tunings, you can store your settings to make your adjustments even faster.
