Ok so first off... Huge fan of Slash's tone. Love it BUT I want something even more bluesy. I guess sort of a mix between Gilmour and Slash's tone. Something smooth and warm I guess. Something that pretty much is good for Rhythm and doesn't jump out. I hate trying to describe the tone I want it's hard as shit to do . Anyways I guess something like that vintage Les Paul tone but softer? Something with pretty much no crunch to it I guess. Oh fuck it just help me
edit: It's routed for two humbuckers soooooo
I don't know what pickup you use currently, or what the electronics layout is, but have you tried rolling off the tone knob? I know that's how Slash gets a lot of his neck pickup tones. He uses a fairly bright and low output pickup in a LP, and then rolls off the tone knob until it's as smooth as he wants it.
