The BP10 has all the specifications and technological features of the CP10, including its low noise characteristics. What's different is that the attack time range has been shortened to better match the needs of low frequency notes. The BP10 brings clarity and eliminates unwanted noise in slapping and picking techniques, giving you the smoothest and most responsive bass sounds. As with the CP10, the sustain time increases as you turn the sustain control clockwise. Too high a setting flattens the dynamics of the output, while a moderate amount can improve consistency from note to note and when different playing techniques are used in the same song.
