KORG Pitchblack X Mini - Mini Chromatic Tuner with ULTRA BUFFER, ±0.1 cent Accuracy, and High-Visibility LED Display

The KORG Pitchblack X Mini is the most compact tuner pedal in the Pitchblack X series—a mini form factor that saves space on your pedalboard without sacrificing pro-level performance. It features the new ULTRA BUFFER to preserve tone over long or complex tuning chains, tuning accuracy of up to ±0.1 cent (strobe mode), and a “bright mode” LED display for brightly lit stages. With quick-reading capabilities and four display modes, it’s designed for guitarists and bassists looking for reliability, accuracy, and visibility in the smallest possible space.

Its chromatic architecture covers E0 (20.60 Hz) to C8 (4,186 Hz) and allows calibration to the A4 concert reference from 436 to 445 Hz in 1 Hz steps. It also includes the “Just Tuning” indication, which visually confirms when the note is perfectly in tune. The PB-X Mini employs ULTRA BUFFER bypass to prevent treble loss and maintain clarity even when the pedal is off, and is powered by a 9 V DC adapter (not included).

Main features

• Ultra-compact mini format (45 × 93 × 43 mm) and weight of 124 g to optimize pedalboard space.
• Integrated ULTRA BUFFER to minimize sonic degradation on long chains and cables.
• Professional accuracy ±0.1 cent in strobe mode, suitable for live and studio use.
• Four meter display modes : Regular, Strobe, Half-Strobe and Mirror.
• High-visibility display with two levels of Bright Mode and “Just-right tuning” function that confirms exact tuning.
• Wide chromatic range : E0–C8; A4 calibration : 436–445 Hz (1 Hz steps).
• Easy connectivity : 6.35 mm mono input and output (BYPASS); 9 V DC socket.
• Low consumption : up to 30 mA.
• Rugged construction with textured finish for heavy duty use.

Benefits for the musician

• Preserved tone thanks to the high-performance buffer , ideal for pedalboards with many meters of cable.
• Instant and accurate reading from different angles, even in bright light, with visual confirmation when you're "on target."
• Surgical accuracy in critical tunings (recording, clean parts, open or alternate tunings).
• Maximum use of space without sacrificing advanced functionality.

Frequently Asked Questions

• Does it have true bypass? The Pitchblack X Mini uses ULTRA BUFFER ( buffered bypass) to maintain tone over long runs.
• Does it work with bass? Yes. Its E0–C8 range covers common low tunings on electric bass.
• Can it be used with a battery? No. This model works with a 9V DC adapter (sold separately).
• Can I change the brightness or meter type? Yes. It has two brightness levels and four display modes selectable from the footswitch.
