The guitar Josh was playing is a BelAire by Motor Ave guitars. (he has like 3 or 4 of them that he tours with)
http://www.motorave.com/And the guy who played the Double Six is Troy Van Leeuwen, their second guitarist. And he'll use that guitar on this songs: My God is the Sun and I Appear Missing (I'm pretty sure he also plays it on ...Like Clockwork, the title track from the album of which all those other listed songs are on). I believe the same double six was played on the track (and live a few times) Another Love Song (off the Songs for the Deaf album).
-My fav band is Queens so feel free to ask any gear related questions about them.
