Boss BP-1W Booster/Preamp

Versatile Analog Sound Shaping

The BP-1W is one of the most flexible boost pedals available, offering three unique operation modes in a single compact stomp. Along with CE and RE vintage modes, a third mode provides a pristine clean boost when you want to pump the volume without added color. The Gain knob allows you to dial in a range of saturation and drive tones unique to each mode, while the Level knob lets you balance the effect/bypass sound or push downstream pedal and amp inputs for further tonal enhancement.

Choose Your Tone Color

CE—This mode reproduces the CE-1 preamp tone, known for its bright, bell-like character and tight low-end response. Tweak the Gain knob to conjure an array of pleasing tones, from mild to aggressive.

RE—This mode reproduces the unique color and response of the RE-201 preamp circuitry. It adds fatness and warmth even at the lowest Gain settings, with increasing saturation as the knob is turned up. You can achieve powerful driven sounds with rich analog compression characteristics, providing foundational vintage color to feed pedals and amps.

NAT—Produces a punchy, natural voice with minimal coloration. The modern analog Waza Craft circuitry provides a wide boost range, delivering top performance for any standard clean boost application.

Two Premium Buffers

The BP-1W features high-quality buffer circuitry with two selectable types. Slide the rear panel switch to choose between the pure signal of a standard buffer or a vintage buffer with lower input impedance. The vintage type produces a warmer tone and a smooth dynamic response, with maximum benefits achieved by connecting a guitar with passive pickups directly to the BP-1W’s input. The standard buffer is always engaged for signal conditioning when the pedal is bypassed, regardless of the buffer switch setting.

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. This enthusiastic spirit continues with the Waza Craft series, bringing you exceptional tone and touch response through carefully selected analog components, refined circuitry, and meticulous attention to detail. 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.
