I think having some more models would be cool - I like the suggestions for more Fenders personally. Although, I have to say that when you get down to listening to these different guitars, the differences between some of them may be a bit more esoteric than we think. I own a AVRI Jazzmaster and while playing it is a unique experience, I've heard it recorded, and I think I could get pretty close to that sound with the Variax now. The Chime model for instance is in that ballpark. It's just one of those things that once you hit the major benchmarks of guitar styles and pickup types, it seems like you'd come up against the law of diminishing returns.

yes! Nylon for sure!

As others have said, Gibson SG and Fender wide range humbuckers would be nice.  Also, a Gibson ES 355 along the lines of B.B. King's Lucille.  Imagine how amazing it would be if L6 could have some special releases of artist-specific guitars to download.
