Pitch=14 is just the name of the mod effects...ignore it.Digitech.com does not allow you to edit the patches already submitted (or, at least, I haven't been able to), so i submitted a corrected version:
You want to set your pitch to -12 (an octave below) set the level to 5. It was the only way I could recreate that low rumble I get from the bassman. For me, that patch is pretty close to my bassman sound with my delay pedal. The bassman is much more "creamier" but after a song or two with the rp400 you forget the differences between the two.
All the best, Fernando
