I made a custom patch by EQ'ing and compressing the heck out of it, added some reverb, and it sounds pretty close to the simulated ones you hear in all the FX pedals. I think the key is to really push the high end (10Khz) and the low (100-150Hz) with fairly tight Q's in the parametric. It will never replace an acoustic, but if you A-B it with a clean electric patch you can certainly hear more of a resemblance to an acoustic guitar.
A bit off topic, I've been working with the software sound called 12 String Acoustic Chords, which plays a full chord with one MIDI note entry, and it includes down and up strums, and by trial and error, I can actually get a pretty nice sounding software acoustic guitar track. I know, why not just record the track with a real guitar... but it's not always the simplest thing to get a nice clean, quiet track, plus I don't have a 12 string 🙂 Try it out, you might be surprised, it's got major and minor chords for sure, but maybe there are other chord type samples available. I've heard of Real Guitar which presumably does the same thing, but it's kinda nice having some similar functionality built into Logic.
