I'm usually pretty lazy but I do take the effort to mic a lot of stuff in "stereo" whenever possible but lately on some things I've been using multiple spot mics in the same position.... which suits my lazy style perfect. I've done this many times on snare, kik, bass, elec guitar but not usually with acoustic instruments - which I've been a lot of doing lately....
I've been mix-matching a condensor and a dynamic with their capsules as close as possible to minimize any phase issues/comb filtering. You can blend these tracks together with a bit of eq for a really nice and different sound...
You can also pan them out a bit and if you boost a freq on one, cut the same freq on the other (watch for any issues in mono though) - which can give the effect of sort of psuedo-stereo effect without using delays.... play with it... it's not as simple as that but it can be cool.... it takes some work but it can work great depending on how the part is used to fill up space in the mix....
you can also reverse/change the volume relationship of the two in a mix for a more exciting verse/chorus transition, etc.
Since I usually use condensors on most acoustic stuff, I've also been compressing and eqing the crap out of the dynamic like I do on a room mic sometimes and push it up to fatten things up a bit in places
or you can just pick what ever track works best in the mix and throw the other one away.... hope this helps
