Well, I think it works quite well with the gain pretty much down. My standard patch has the gain at 4.5, though, and it even doesn't clip when I use my Ibanez 335 clone and add a little bit of push from the Vetta Comp. So maybe it's indeed your interface's input level driving it too hard with HXN's input slider at the default value.
Here's a little clip that I recorded quite straight after it was released (sorry, posted that somewhere else before), I think it's pretty clean (maybe a little tad of hair when I pick harder, but I had the gain a little higher back then):
All guitars are using the same patch.
