I've been using tone matching for a long time now. My first IR on this was posted in 2012 on Axe Exchange under the name "Tommy". It is matched to Tommy Emmanuel's Blue Moon as Cooper suggested above. More recently I did another tone match using the Acoustic guitar intro of "Crazy On You" by heart. That one is really good because it does not have significant reverb in it, as opposed to Tommy's which is drowned in reverb.
I use Smoothing quite a bit on this. otherwise the comb filtering effect is too strong and you get the nasal effect. Anyhow, I'm attaching some results here for you guys to try. These are shot using my Parker Deluxe so your milage will vary as all piezo's are not created equal.
My final results are quite good as long as you don't play with someone playing acoustic next to you. If you do, the difference is apparent.
