KORG AW-OTB - OLED Clip-On Bass Tuner with Tempo Detection and ±0.1 cent Accuracy

The KORG AW-OTB is a bass-specific clip-on chromatic tuner that combines a high-contrast OLED display with bass- optimized electronics, delivering immediate and stable readouts even on the Low-B string. It features 11 display types (including strobe mode ) and achieves an accuracy of up to ±0.1 cent in strobe for fine-tuning live and studio settings. A tempo detection function identifies the beat between 80–160 bpm , useful for locking in your groove while practicing. With A4 calibration = 436–445 Hz , setting backup memory , and intelligent auto-off , the AW-OTB becomes a reliable and compact tool for demanding bassists.

The clip offers a firm hold and flexible adjustment via an articulating arm and ball joint, allowing the display to be positioned from any angle. With a single AAA battery , it provides approximately 18 hours of continuous battery life. Its chromatic range A0–C8 comfortably covers the register of the electric bass, and the ultra-lightweight design makes it easy to carry around in a gig bag or case every day.
