The BOSS BP-1W combines three analog preamp and boost voices in a compact Waza Craft pedal. CE mode captures the bright preamp character of the CE-1, RE mode provides the warmer preamp character of the RE-201, and NAT mode delivers a natural clean boost. These are preamp voicings, not chorus or echo effects.

Gain controls saturation and Level adjusts the output. Choose Standard or Vintage input-buffer response when the effect is on; bypass uses the standard buffer.

Power it with a 9V alkaline battery or an optional BOSS PSA-series adapter. The standard package includes a 9V battery and safety documentation. Power adapter and instrument cables are sold separately. Guitar and cables shown in lifestyle photos are not included.
