I love the Elitists (and have 2, as well as a Casino and some Epi LP's!). The video you were watching must have been older...?
I'm not a big 3rd Day fan, but I did work a special duty shift as security for one of their concerts about 2 months ago - their guitarist was playing PRS - exclusively. He probably had 5-6 PRS (Customs or Standards, I don't know which) - a Mira - and an SE Singlecut. I talked to his guitar tech after the show, and he was saying that a couple of the guitars were one offs from PRS, and I asked him what he thought of the SE vs. Epiphone - he said that he's gutted the one that was used during the show and upgraded everything, but that he liked the SE series PRS guitars much more than Epis.
Not that I agree - just what he said.
The band that is touring with them (I can't remember the name...) is from Australia, and were brought to the USA by 3rd Day to tour with them (according to announcements during the show) - I talked to their guitarist for a few minutes after their set, and we talked guitars some. I mentioned my R8 and '69 Deluxe, and he said that he really likes Gibson guitars, but now that he's sponsored by PRS, that is all he plays. I'm assuming that he got his sponsorship through 3rd Day, who is clearly sponsored by PRS, at least currently...
