I am about to buy a new rig, and expect it will be my last. This one would be for some recording, gigging (sometimes the only source for bass, but generally only stage monitor), practice, and rehearsal. I want a valve amp this time around, so I limited the choices to only those. I don't mind having two cabs, one for most purposes, and both together when I need to be loud, but I really only want one head. So, if you could only have one bass rig for everything, which one would it be? Feel free to mention the cab(s) you'd use with the head you chose.
