Its really tricky to dial in the drive blocks to match a pedal, but in 99% of cases, its doable and you can get them where an a/b at a given setting is pretty tough to tell blind. Now, one caveat for that is on a pedal you might just roll back the vol pot and get a different tone and on the Axe you do the same and it won't sound the same. You might need to tweak more parameters, which I guess could be done with scenes, but point being, a given setting on a pedal can usually be matching on the Axe
I can't even begin to count the number of stomp boxes I've bought over the years, some several times over, thinking I was missing them in the Axe. Latest being the SKreddy Lunar Module. Great sounding pedal, but then with enough tweaks I can exactly match a given setting in the Axe.
There are so many parameters that can shape the tone of a drive pedal, high and low cut ranges, the EQ of the pedal (great way to dial in different era Muff's btw), parameteric mid control, the type of clipping etc. Its vast and not always super intuitive, but the tone can usually end up getting there.
I a/b with a the hardware fuzz and always end up selling the pedal because I know the Axe can match it, tonally.
Sometimes you also need to stack 2 drives, or a fuzz into a cleaner drive etc, which is even more tricky and parameters to adjust.
People knock the drives because they don't sound like their favorite dirt pedal, at least just from the get-go, or with just a basic gain/tone/vol adjustment matching the hardware knobs, but with enough work, I think the drives can really do what people want
I do fully agree taht it would be nice if it was more press and play, but maybe with some additional drive block settings on the exchange we could get closer to being able to have something a bit quicker to access
