What's up with Rivers going back to the old Blue Warmoth strat copy on the last couple of shows?  Perhaps he is getting a little nostalgic?  

I may be missing some but this is what I can remember River's playing on tour over the years (I'm sure in studio he has a much bigger arsenal)  Try to pick your favorite.

Blue strat copy

White Gibson SG

Honeyburst/sunburst Gibson Les pauls 

Black Gibson Explorer.

Again I'm probably missing some, but this was just off the top of my head.

I like when he plays Les Pauls the most.  Like the footage of them rehearsing Prodigy lover from their DVD is really cool. Rivers has a tie on and he is rocking the Les Paul.
