Ok, late to the party as usual, but Ive enjoyed reading this thread. Here is my paltry contribution:
This patch I use for some slap (RHCP Higher Ground) but also for brighter, lighter distortion (think Greenday?):
#1 Bassdrive: bass 3, trebl 0, prese 2, gain 70, blend 30, level 35, mid 7
#2 SVT: bass 6, mid 2, trebl 2, mid f 200, gain 40, level 25, ultra both, cab flip, mix 50. I have the overall patch level set to 50. I try to set my patch levels to work with all of my other volume settings with no adjustments.
Another patch that the guys in my band seem to think sounds good is also one I use on higher ground, it is for the wah type effect. I use it still slapping:
#1 Opt comp- drive 8, tone 50, level 50
#2 BassAutoWah- sense 4, reso 5, dry 0, level 50
#3 Bassdrive- bass 6, trebl -2, prese -3, gain 30, blend 50, level 75, mid 0
#4 SVT- bass 6, mid -3, treb -3, mid f 200, gain 40, level 47, ultra off, cab flip, mix 50.
Overall patch level is 80.
Let me know if you try these and have any suggestions on revisions.
