Love the thing. Now i've been craving for an extension cab. So what do you guys got? I've been looking at the 115Rbs 1x15 cab for its price, but will that cab be able to handle the amp? I've got two guitar players in my rock band, will that 2x10 + 1x15 combination work to match them? or should i get the bigger brother, THE 115 RBH? And oh, yeah. i'm also considering an 4x10 cab!!! so, what do you recommend? other brands are welcome too! I dont discriminate!!!
