I'd be very surprised if I didn't since I do that by default. Maybe it's worn out, which would also surprise me, or maybe you're deaf Let me listen and listen for it.
Speaking of which, I've found Dunlop Max Grip to be an even better choice than Herdims for getting that grit on Edge-ish riffs. THey're absolutely not good for strumming though.
Comparing myself to the real thing, the Herdim grit isn't all that audible in the verses on either, because it's played with a quite light touch, but I do think it's there when the picking has a bit more umph.
Maybe Edge has his stuff a bit more on the verge of breakup than I do and that is what you're hearing.
