I find Crush Station very useful but I’m not a metal guy.

I like to hear my guitar through the grind.

Crush Station lets the sound of my guitar come through.

Try turning up the sustain.

I have found that adding sustain does more than just add sustain it also seems to darken tone which takes the sound of my guitar out of the equation.

If you’re looking for a darker tone that masks the sound of the guitar, like a TS9 or equivalent, I suggest you try sustain.

I don’t think any amount of tweaking is going to satisfy someone into metal or grunge.

For classic rock I think it’s damned near perfect.

I’ve taken two (of four) OD/Dist pedals out of my board because the H9 sounds better to my ears.

Still have not tried Sculpt yet.
