OK. I've tried. I've tried on more than one occasion. But the sound guy keeps telling me to turn off the cab sim on the Le Bass. No matter what I do he says its "tubby" or "boomy" with no articulation. Even if I cut back bass and/or add in treble... same directive. Turn off the cab sim.
I would wager that you play with your fingers.
With me being a plectrum player, I guarantee he would urge me to turn and leave it on.
Different strokes and that's OK.
