Korg PBXPRO Pitchblack X Pro Rackmount Guitar Tuner

The Korg Pitchblack X Pro is a rackmount tuner built for musicians who need fast, accurate tuning in demanding live and studio environments. Its newly developed ULTRA BUFFER circuit actively maintains your guitar's signal strength and tonal clarity across long cable runs — a common challenge in professional rack setups with multiple effects and switching systems. When working with vintage pedals or signal chains that benefit from an unbuffered path, you can switch to True Bypass mode with the flip of a switch.

Visibility is a clear priority in the Pitchblack X Pro's design. The large multicolored LED meter is readable from a distance and under bright stage lighting, and four display modes — Regular, Strobe, Half-Strobe, and Focus — let you choose the tuning feedback style that matches your workflow. The unit detects pitches from E0 (20.60 Hz) through C8 (4,186 Hz) with accuracy down to +/- 0.1 cent in Strobe mode, covering standard and extended-range instruments with confidence. A built-in cable tester rounds out the feature set, letting you diagnose signal problems on the spot without pulling additional gear from your road case.
