The Korg Pitchblack Advance Pedal Tuner is next instalment in Korgs Pitchblack series offering everything the previous models had – with enhanced capabilities. The pedal features a sleek slanted design with a large easy to read LED screen as well as four different meter display modes so you can use the one best suited to your playing style. True bypass switching as well as special circuitry and software provide a crystal-clear noiseless operation while its enhanced efficacy and long life design provide an extremely long battery life. With the ability to also power other pedals the Pitchblack Advance is the ultimate tuner pedal Korg has to offer for guitarists. Four meter display modes The Korg Pitchblack Advance Pedal Tuner is equipped with four different meter display modes to choose from with regular strobe half-strobe and mirror modes. While regular offers the standard tuning experience strobe and half strobe provide a direction and speed meter movement for easy visualisation. Also when using strobe mode the pedal allows ultra-high-precision tuning with +/- 0.1 cent accuracy. In mirror mode two LEDs move from left and right towards the centre as you tune. True bypass output The Korg Pitchblack Advance Pedal Tuner is capable of muting the input signal for silent tuning and when youre not tuning the input is passed directly to the output jack without being affected by any circuitry. This means that no matter where in your chain you place the Pitchblack the signal will pass straight though without going through the internal buffer amp ensuring that the sounds youve created using your effects will not be coloured in any way. Features parallel connection for powering other pedals If a separately sold AC adaptor is used the DC OUT jack can supply power to another effect unit. Since a dedicated power supply circuit is provided for DC OUT it can provide stable and noiseless 9V 200 mA power. Completely eliminate unwanted noise The Korg Pitchblack Advance Pedal Tuner is built to provide a stable environment for players and features a special circuit to suppress any unwanted noise that may occur from interference between pedals using the same power supply. This allows it to completely eliminate the unwanted noise and provide a quiet operation. Extremely long battery life With eight years of experimentation with the Pitchblack series the Advanced tuner has brought its high efficiency and long life design to a higher pinnacle. Achieving ultra-long-life operation the pedal can last approximately 30 hours on zinc-carbon batteries and approximately 60 hours on alkaline batteries.
