MXR bass DI, really agressive distortion. We have one in the studio. From what I've tried with this pedal, you can go for two different sounds, you can :
- plug it between the bass and your amp, and use it very slightly, just to get this "oil thing" going into the highs (think the album Arrows from STONEGARD, or the last Tool).
- plug it between the bass and your amp, and use it with gain around 12 o'clock, removing some highs on the EQ, to get an agressive like hell distorting (think a guitar dist). Then with another EQ, keep only the "300 Hz to 2 Khz" band, and boost the 700-800 Hz growl. Think Meshuggah, In Flames...
I have an audio extract where we used this pedal, more corresponding to the first case I described :
