Interestingly enough, I compared it last night with my racktifier. The red was pretty close - stock wasn't bad, but my mods were closer imho. Stock seemed a bit muddy.
Orange channel MTS vs orange channel racktifier - my MTS mod is a lot more drastic than the real deal, but that's a good thing in my opinion - makes the module more versatile.
Overall, I was surprised at how well even the stock held up against a real recto. Again, just the mud and lack of clarity/high end was the real difference. Newer versions of the treadplate (or whatever they call it) have much tighter bass caps, so that helps with the mud. Add clarity/warmth mods and the orange channel and it's pretty useful
