I wouldn't be suprised if PRS guitars sponsered the tour

I'm a gear nerd :D

seriously I know what each band uses(except 10 Years, apparently both guitarists quit the band so no idea)

Sevendust:
Clint Lowery-PRS Custom 22, PRS Singlecut, PRS Singlecut 7 string
John Connoly-Dean Soltero, Dean Z
Vinnie Hornsby-Epiphone Les Paul, Dean Soltero

Puddle Of Mudd:
Wes Scantlin-Gibson Les Paul
Paul Phillips-PRS Custom 24, PRS Singlecut
Doug Ardito-Fender P-Bass(reverse headstock)

Chevelle:
Pete Loeffler-PRS Custom 24
Dean Bernardini-Gibson Thunderbird

Shinedown:
Zach Myers-PRS Zach Myers SE, PRS Chris Henderson, Fender Telecaster, Gibson Les Paul, Schecter Syn Gates, etc.
Eric Bass-Dean Eric Bass, Dean Hillsboro, Dean Demonator

wow i did not know that.

the funny thing being the other 3 mentioned were endorsing PRS before Shinedown even released a record(Clint actually signed on with them in the late 90's)

true very true. but that is a pretty cool observation i only knew for sure about zach and prs.

Although it should also be mentioned that Dean(who makes Eric's sig bass) also endorses Vinnie and John from Sevendust

Ha, nice pick up. You are probably right about that.
