Natural Sound with Advanced BOSS Technology
In developing the XS series, BOSS engineers pioneered new methods to advance real-time pitch shifting and eliminate the tonal artifacts common in conventional designs.

Your instrument’s attack and tonal character are fully preserved, and even complex chords and sustained lead tones—typically a challenge for pitch shifters—are reproduced with stunning clarity.
