Boss BP-1W Booster/Preamp

The vintage BOSS CE-1 Chorus Ensemble and RE-201 Space Echo are legendary for their inspiring and influential effect sounds.
But they’re also loved for their variable analog preamp circuitry, which instantly infuses any guitar tone with character, body, and richness. With the BP-1W, you can now access these two classic
preamp tones in a premium Waza Craft pedal, along with a natural, clear voice that functions as a standard clean boost.

With its three operation modes, the BP-1W is one of the most flexible boost pedals available. Along with CE and RE modes, a third mode provides a pristine clean boost to pump the volume without added color. The Gain knob offers a range of saturation and drive tones unique to each mode, while the Level knob lets the player balance the effect/bypass sound or push downstream pedal and amp inputs for further tonal enhancement.
The BP-1W also features high-quality buffer circuitry with two selectable types. Sliding the rear panel switch provides access to 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.
