Hi guys! I'm about to change my rig from an Ampeg SVT 3 Pro to a pre+poweramp setup. I've put my eyes on a Peavey Max Bass Preamp, so for the preamp section I'm ok, but I really don't know which power amp could do the job... Any suggestion? By the way I only got an Ashdown 414 MAG cabinet that's a 4x10'' 450W @ 4 Ohm so I think I don't really need an extremely powerful PA...or do I? What about getting an extra 1x15'' cab to give my rig more power? Mmmmmh.... HELP ME PLEASE!!!
