I have a 2002 Peavey Firebass...searching this site has brought up very little on it . I'm beginning to feel shut out here. I've spent the last week around an Avalon 737sp preamp...dayum if I don't get a valve-driven pre and run it into the Peavey's power amp input . Are the heads any good? I mean come on, 4000000000000000 posts and jsut six threads, none of which are to do wit this head?
