Independent shopping perspective
Designed for bass, the AW-OTB clips onto the instrument and uses an OLED display with a viewable screen from different angles. Its dedicated low-frequency circuit recognizes frequencies below 100 Hz, including the range needed for extended-range basses with five or more strings. Strobe mode reaches ±0.1-cent precision, and 11 display modes provide different ways to follow pitch. A tempo finder reads bass-line tempo from 80 to 160 bpm, while the adjustable clip lets you place the display where it is easiest to see.
