Started playing out with my band recently and have come realize the my 410 is not cutting it. I have just been running a DI into the house then pumping some "thump" through the house subs. Not sure that I want to keep doing that. Do I have to add a 15 to my rig? I don't really want to haul around more stuff or get a super cab that takes 4 guys to move. What are my options? Kind of thinking about saving my pennies for the likes of a Shroeder 21012, but thats lots o money on something that I can't demo. Maybe the Acme B-4, a little cheaper? Maybe I'll just bite the bullet and get a 15 to set the 410 on. Well, thanks for the input. For what its worth I play a Spector Rebop 4string tuned low and my amp is a 400+.
