I believe I've read that he uses Vox ac30's. I like his tone as well. I saw them live when they first came out. They were outstanding. They did some great Police covers also. My drummer always wants me to do "King" during worship but it is SO high.
I saw them in April with Paul Coleman and Building 429. I was able to get pretty close to the stage. There was a lot of gear on stage, but from what I could tell he was playing through a Marshall head (not sure what model). Pedalwise, I saw a few Boss pedals - couldn't make out the rest. He played a Firebird most of the show and his tone was great.
I second that, John. Linconln is a monster player and one of my favorites. I try to do at least one of his songs each week during worship. I don't know how he gets such great tone from the XT Live. I tried one and just couldn't warm up to it. I would like to try again as I'm sure it just takes time to tweak. I think you really have to do some serious eq adjusting to get it sounding right. Have you heard his new live cd? Its one of the best cds I've heard in a long time.
I still need to pick up the new CD. I heard there are some cool videos on there (or the corresponding worship tools kit).
Lincoln said he played along with a bunch of his favorite worship songs and then went back at tweaked the POD until the sounds matched the original recording. It would be nice to get those patches I suppose. We still wouldn't sound like him though.
Oh, by the way, there is a christian musician summit in Seattle next month. Lincoln is gonna be there along with tons of other great players and worship leaders. I'm still not sure if I'm gonna be able to make it due to funds, but I'm gonna try. It would be cool to hook up with some Gear Page forumites there. Here is a link.
John & Josh - Lincoln Brewster is one of my favorites too. His website has been updated, but he still has a FAQ section on his Gearpage. It looks like he's been using a POD since his debut album, both live and in the studio. He seems pretty eclectic with his gear (Fender, Budda, Line6, Rocktron, etc.). I agree with you guys - he could probably get great tone with about anything!
