The Pitchblack X not only features a true bypass for outputting the sound exactly as it was input but now includes a built-in Ultra Buffer. Why is this important?The majority of electric guitars use passive pickups with a high impedance output. When you are using a cable there are a loss of tone, usually high frequencies, after about 6 m (around 18 feet) and this problem worsens the longer your cable. A buffer boosts the signal over long cables to avoid loss of tone, keeping it clean and clear - even when your pedal is off. The Ultra Buffer enhances the sound quality in bypass mode so that you can still maintain audio quality even when using a long cable to connect to the tuner, or when inserting the tuner into a complex effects board. On the Pitchblack X, you can switch between true bypass and the Ultra Buffer, according to your tastes and performance environment. Meter LED Offers Bright ModeThe bright mode (brightness) can be set at one of two levels, so that you can be sure to see the tuner display even better in situations where visibility is complex, such as brightly lit stages and bright outdoor environments. Ultra-High TuningThe Pitchblack X offers exact and accurate tuning within a precision of ±0.1 cents when in Strobe mode, making it ideal for situations where the tuning must be absolutely right whether performing or recording. Four Meter Display ModesAside from the typical Regular mode, you can use Strobe and Half Strobe modes to indicate changes in pitch by the direction and speed that the meter is flowing in to distinguish even the finest differences in pitch; and you can use Mirror mode to see two LEDs on the left and right crossing together towards the center as you tune your instrument. Built-In Just-Right Tuning DisplayThe Pitchblack X features a new just-right tuning display function, which makes the triangular LEDs on both sides blink when the tuning is correct, helping tuning be a stress-free experience. Sturdy HousingThe Pitchblack X is housed in a robust aluminum case with a strong scratch-resistant coating. It works on 9 V batteries, which is perfect for players who don’t carry around an effects board, and there is an optional AC adaptor if required. | Korg PBX Pitchblack X Guitar Pedal Tuner with Ultra Buffer
