Boss BD-2 Blues Driver Pedal The Boss BD-2 Blues Driver Pedal gives you the classic, bluesy sound of an overdriven vintage tube amp in a compact pedal. The BD-2 gives you all the textures you need to scream, sing, or cry. Can also be used for warm distortion with a higher level of responsiveness than most distortion boxes. Controls for Gain, Tone, and overall Level. Great for blues and rock. Expect subtle overdrive to ripping amp tones from your Boss BD-2 Blues Driver Pedal.
