Korg PBCS Guitar Tuner Review (April 2024)


Last updated on April 9, 2024 4:51 pm Details


In this review post, we’re going to be discussing the Korg PBCS Guitar Tuner, including an overview of its unique features.

Product Description

Since its debut in 2008, the KORG Pitchblack pedal tuner has earned a reputation as a trusted and indispensable part of every pedal board, thanks to its high sensitivity, great visibility, and sturdy construction. Now, to continue the legacy of Pitchblack, we introduce the Pitchblack Custom.

The Pitchblack Custom features the first vertical 3D visual meter on a pedal tuner. Three-dimensional lights and versatile display modes deliver an unprecedented level of visibility. In addition to allowing ultra-high +/- 0.1 cents tuning precision, it features true bypass switching that prevents any coloration of your tone. Designed with the needs of professionals in mind, the Pitchblack Custom will provide years of trouble-free operation. The durable aluminum die-cast body provides a DC output that allows parallel connection for powering other effects pedals. The Pitchblack Custom offers unbeatable visibility and accuracy for all guitarists and bassists and is the clear choice for professionals.

The 3D visual meter exemplifies the Custom Shop series. A large and easily visible note name indication and the distinct movement of brightly illuminated LEDs make the pitch difference and change instantly recognizable. This new 3D visual meter makes it simple to tune with a precision of ±0.1 cent.

Designed with the professional user in mind, KORG’s Pitchblack Custom offers extremely accurate tuning with a detection range of +/- 0.1 cents, a level of precision that is uncommon for pedal tuners. With the Pitchblack Custom, players of all styles can now enjoy the same ultra-high precision offered in KORG’s flagship tuner, the Pitchblack Pro.

Choose from four meter display modes to suit your playing style. In addition to the standard “Regular A mode,” you can use “Strobe mode” or “Half-strobe mode” in which the direction and speed of meter movement indicate the pitch change for easy visualization of even minute differences, as well as “Regular B mode” in which the meter rises by being stacked from bottom to top toward a reference line – a mode that’s possible only with KORG’s vertical display.

Our Verdict

Korg’s true-bypass Pitchblack Custom joins the ranks of its predecessor, but with several huge changes: a detection range of +/- 0.1 cents, triple the battery life, a sleeker design, and a smaller container with a larger display. The 3-D vertical strobe-esque display of the Pitchblack Custom is outstanding, and it gives you faith that this black box can perform its tasks on the darkest of stages.
