Hi!
I have always been a fan of players like Lee Ritenour Carlos Allarendo and Luis Salinas. To play that style I've always been most comfortable playing a D-style sound as it is both warm and fat while still being distinctive.
I learned a trick from a Swedish jazz player on how to get a distinct but still darkish jazzier sound with a neck humbucker. Push the treble on the amp and decrease the tone control on the guitar. So when I was profiling a tried this and got, what I consider, a very good smooth jazz clean sound. Fat and warm without being too wolly which is often the case. It's also quite dynamic. If you play this profile without turning down the guitar tone it wills sound shrill.
