Korg PITCHBLACK POLY PB-03 Polyphonic Pedal Tuner

The Korg Pitchblack Poly PB-03 is designed for players who want to check their tuning quickly without stepping away from the pedalboard. Its polyphonic mode lets you strum multiple strings and see which ones need attention, while its chromatic single-note mode provides precise adjustment when you tune each string. It works with guitar and bass and is useful for rehearsals, live sets and everyday practice.

Check several strings in one strum

Polyphonic tuning gives you an immediate overview of your strings, which is particularly helpful between songs or while setting up. If one or more strings are out of tune, switch your attention to the individual notes and bring them into place. The tuner automatically detects guitar or bass input for its polyphonic function. For unfamiliar tunings, check the appropriate tuning mode and verify individual string pitches instead of relying solely on the overview.

Four display modes to suit your preference

The Pitchblack Poly offers Regular Meter, Full Strobe, Half Strobe and Split display modes. Some players prefer a conventional meter for quick adjustments; others like a strobe-style indication when fine-tuning intonation or preparing for recording. The stated detection range is E0 to C8, with tuning accuracy of approximately ±1 cent. Concert-pitch calibration is adjustable from A4 = 436 to 445 Hz.

Pedalboard-friendly connections and power

True bypass switching means your guitar signal is passed through without the tuner’s active circuit when it is bypassed. The pedal has standard quarter-inch input and bypass output jacks, along with 9V DC input and output connections. It can run from a 9V battery or a suitable 9V adapter; the DC output can supply power to another compatible device within the manufacturer’s stated limit. Always check polarity and current requirements before connecting extra pedals.

Who should choose the PB-03?

This tuner is a sensible option for guitarists and bassists who often need a fast visual check of all their strings but also want accurate single-note tuning. Its die-cast pedal format suits a working board better than a clip-on tuner when you want a dedicated foot-controlled solution. Barbad Musical Instruments can help you check the correct power arrangement and compare it with simpler chromatic tuners in the UAE.
