Waza Craft: The Art of Superior Tone

Since the beginning, the engineers at BOSS have been committed to achieving the finest guitar tones using any technology necessary, from old-school analog circuits to high-tech DSP. Continuing this enthusiastic spirit, we are pleased to introduce the Waza Craft series. In Japan, “Waza” is the term for art and technique, and these special edition pedals proudly carry the Waza symbol to represent the pinnacle of BOSS design and craftsmanship. With final sound approval carried out by BOSS in Japan, the Waza Craft series brings you exceptional tone and touch response through carefully selected analog components, refined circuitry, and meticulous attention to detail.
