In my opinion, the start to getting a Jaco like tone out of an Alembic is to emphasize the bridge pickup, set the bridge filter about 1/4 open and maximize the q switch or cvq on the bridge filter. The neck pickup and filter should probably emphasize bassiness but in a very subtle way. From there, I think it all comes down to technique and wood recipe. I am no where near a Jaco like talent player but have heard others play my Alembic and have it sound very Jaco like. This is even on my fretted Europa 5 string w/ Series I electronics. My guess is you can get something close on your MK5 pictured above (BTW, one beautiful bass). I suppose if you were to de-fret it, that would take it the next step (although I like the looks of it as it is).
I hope this helps.
