The Korg Pitchblack Polyphonic Guitar Pedal Tuner is a floor pedal polyphonic tuner, about the size of one effect pedal. The tuner shows the tuning of all strings at once, which saves time when tuning your instrument. Additionally, being able to tune all strings at the same time ensures that the relative tuning between strings is consistent. This is especially important in a floating tremolo system wherein the tuning of one string is not just harmonically but mechanically effected by the tension and tuning of the other strings.
The tuner features String Seeker which automatically switches from displaying the polyphonic tuning of all the strings to the tuning of the one string you are adjusting. This allows you to rapidly switch between fine-tuning an individual string and checking the tuning of all the strings.
The upper display of the tuner features a row of blue and white LEDs that indicate if the pitch of the note being tuned is sharp or flat. The lower display uses green and red LEDs to represent the individual strings. The lower display will switch between green LEDs in polyphonic mode and red LEDs in the shape of the letter of the note in monophonic mode. The tuner features four different display modes with different lighting patterns so that you may choose the way the tuning is represented. In all modes, the display is clearly visible from any viewing angle in daylight, stage light, or no light.
The tuner operates on an included 9 VDC battery or optional 9 VAC adapter sold separately. The unit also includes a 9 VDC cascading output jack that allows you to power up to 200 mA worth of additional pedals on your pedalboard.
Flat, Capo, and Drop-D Tunings
The tuner can be calibrated for different tuning such as Flat from 1 to 5 semitones down, Capo from 1 to 7 semitones up, and Drop-D wherein the guitar's 6th string is tuned to D
When the tuner switch is activated, no signal passes through the tuner, allowing for silent tuning. When the switch is not activated, the signal passes throguh the pedal without being affected by the tuner
