For those that don't like the Softube saturation knob, I totally get it. This thing goes from off to TOO distorted much too quickly.
I have found a few things I like it on and you may find the same in experimenting:
1. Kick
2. Snare
3. Toms
4. Bass that needs some dirt
5. Guitars that I want more distorted
I have no user for it outside of these things, and only use on them to taste if the style is appropriate.
Peace,
Tunes
