Description
Boss BP-1W Booster/Preamp Effect Pedal For Electric Guitar
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.
