The BOSS BP-1W is a premium booster and preamp pedal that features innovative Waza Craft technology to provide a rich analog tone. It allows access to two classic preamp sounds, historically derived from the revered CE-1 Chorus Ensemble and the RE-201 Space Echo. Guitarists can choose among three selectable modes: CE for a bright and bell-like sound, RE for a warm and fat tone, and NAT for a pristine clean boost with minimal coloration. The pedal includes gain and level knobs for customizing saturation and overall volume. Its versatile design makes it a valuable addition to any guitarist's pedalboard, effectively enhancing the core tone without the need for vintage originals.
