The Pitchblack X series has been designed to become the new benchmark for pedal-format tuners. These tuners offer unprecedented readability and precision, so you can tune in the best possible conditions, even in the dark of a stage between two songs. The built-in Ultra Buffer adjusts the impedance of the sound before it passes through the effects chain to avoid signal loss. It can be deactivated on the PB-X and PB-XS models. With their rigid, durable casing, Pitchblack Xs will be with you, wherever you go, for years to come.
