The Boss BD-2 Blues Driver Pedal captures the classic, bluesy sound of an overdriven vintage tube amp in a small package. The BD-2 provides all of the textures required to scream, sing, or cry. It can also be used for warm distortion with more responsiveness than most distortion boxes. Gain, Tone, and overall Level controls are available. Excellent for blues and rock. The Boss BD-2 Blues Driver Pedal can produce everything from subtle overdrive to ripping amp tones.
