What's been working for me is piezo bridge p/u (similar to Ghost) using a profile from RE called 'Acoustic GSP'. Use it for both fingerpicking and strumming. Haven't really tried it with magnetic p/u but I bet it would get pretty close. I tried all of the other acoustic profiles and that was the one that sounded most convincing to me.
I own the Boss Acoustic pedal and it just adds too much noise to be usable.
