The Boss ODB-3 Bass OverDrive Pedal is tailored to meet the demands of today's bassist with a wide variation of sharply contoured sounds. You can go from a mild overdrive to a hard distortion. The Boss ODB-3 covers the entire spectrum, including 5-string basses, so there's no muddiness, even on the lowest notes. Boss provides a balance control so you can mix the effect with the bass signal to keep the power and presence of the original sound. The ODB-3 Bass OverDrive Pedal can also be used as a 2-band EQ.
