I use a similar setting, just blended with the sfxsound X&M.
Supersynth and M9 affect the tone above 300Hz and the Octabass below it.
In the rack it goes to the TBP-1 and in the effects way through the MicroThumpinator and the dbx 160A.

I love it. Great flexibility with the M9 and still the nice bottom due to the X&M.
