Yes, there will be vocals eventually. They will likely be similar to the vocals on the pre-production songs up on my band's page at the moment (see link below), although the singer and I haven't sat down and figured out the best way to approach the song vocally. A few parts generally get changed when we're tracking pre-production, some parts a little and some parts get totally reworked.
As for the guitars, it's a Behringer V-Amp with some hefty EQing on it. I suppose it could be a bit brighter, but I think it's fine for pre-production!
