Im looking to upgrade my rig a bit, and want to know what id be better off with. I currently play through a GK backline 115 combo, and i like its tone, its just not powerful enough. I dont gig enough or at big enough places to require more than 300 watts of power, so for a head i am probably going to get a GK rb400 IV since ive played it before at a local shop and liked it. What i really need to know is what cab to get. Again, i dont need anything too powerful, so i was looking at either getting a gk backline 4x10, a hartke transporter 4x10, or a carvin br series 2x10, all of which range from 250 to 300 new. so which of these cabs would most likely be the best with the gk head?
