I haven't really done any comparative listening at this point and I mean any.
Sure I've listened to some old boots since but I don't see the point in comparing the two guys.
At least not until I hear something that stands out in a weird way or something.
I have to admit that I don't really know what the "Duff's tone" is.
Sure I've heard all the GNR records but after that I haven't followed him much at all.
I know I've heard some Velvet Revolver on the radio but I couldn't tell you the name of one of their songs.
As far as his Loaded band goes I don't know anything at all about them but I've been snooping around and trying to find out what I can.
To that end I've checked out a few sites.
The official site was recommended to me by one of our members.

You'd have to ask Duff to get an answer to your question but I imagine playing in a band you started vs playing in a band that you join in progress so to speak are two different animals each with their own unique pluses and minuses.
