The BOSS XS-1 Poly Shifter brings next-level pitch-shifting power to your pedalboard, combining decades of Roland and BOSS innovation with a compact, road-ready design. At its core is advanced polyphonic pitch-shifting technology, delivering smooth, precise tracking whether you're playing single notes or dense chords. With high-quality 24-bit AD conversion enhanced by BOSS's proprietary Adaptive Focus (AF) method, the XS-1 ensures exceptional clarity and an improved signal-to-noise ratio. The 32-bit DA conversion and 48 kHz sampling frequency further guarantee pristine audio performance, giving players studio-grade sound on stage or in the studio. Designed to handle a wide range of playing dynamics, the XS-1 boasts an impressive input range, buffered bypass for tonal integrity, and flexible connectivity including dedicated control/expression inputs.

Beyond its sonic precision, the XS-1 is built for creative expression and ease of use. Players can shape their sound with intuitive onboard controls, including BALANCE and SHIFT knobs, plus dedicated switches for pedal mode and shift direction, making it simple to dial in subtle harmonies or extreme pitch effects. A bright CHECK indicator doubles as a battery status monitor, while rugged input/output jacks and a CTL/EXP input expand the pedal's versatility in live setups. Power comes from either an AC adaptor or a single 9V battery, with approximately three hours of continuous use on alkaline power, ensuring reliable operation on the go. Compact, powerful, and loaded with cutting-edge digital processing, the BOSS XS-1 Poly Shifter is a must-have tool for guitarists and bassists seeking dynamic pitch effects with uncompromising sound quality.
