Exactly! Just recently I discovered this by accident. I never thought that boosting the highs in conjuction with rolling back the VTC would do that. I ignored the VTC for a long time because it just sounded muddy. Now, for some fingerstyle, I boost the highs quite a bit, engage the VTC quite a bit and favor the bridge and it gives that killer midrange "thumpity bop" Jaco-ish tone.
+1.. on a side note, this is what makes the treble voicing capability of the Markbass amps very cool... they have the same thing 'on board'... a VTC type treble roll-off along with a high shelving point active treble control. There's lot's of different 'top end' flavors using the passive cut and active boost!
