I am currently in the process of spending my hard earned money on a new intermidate rig. It looks like I'll be getting the Behringer Head and the Ashdown MAG 115T cab. But after seeing rave reviews about the Sansamp Driver DI, I was thinking of getting one. But where would it go?? Would it be useful in a set-up like this?? Do I need one or does the head give me enough tone shaping capabilites??
