I was working on Killswitch's distorted bass sound last night but couldn't get close enough with Ozone no matter what.

Till, have you ever tried to profile a distorted bass sound?
No, not yet. You mean that ozone couldnt match the tone? I only had the strange behaviour that for exteme scoop guitar sounds (like demanfacture, pantera or life of agony) the ozone plugin got the sound pretty good, but the KPA could not profile it with the exact same sound. This only seems to happen with those extreme scoops.
For bass, i am not sure if tonematching is capable of reproducing stuff like compression, which is a major component of a bass sound.
The cliff burton solo from kill em all might be easy to match because of the high distortion, maybe i will give it try.
