The clamp of the CRAFTER TG-200K contains a piezo pickup which directly picks up and analyzes the vibrations of the instrument. This allows tuning even in noisy environments. Alternatively, tuning can also be done via the integrated mini-microphone. The display is quiet and flutter-free. The instrument displays the recognized note directly. Fine tuning can be performed via a simulated pointer display. Synchronously to this, the illuminated background color also changes from orange to green when the note fits perfectly.
