I have an Epi 4-10UL run through a Read Purity and Stewart World 2.1. In my new band's practice space, I've noticed while the volume and cutting power is tremendous, the cab oddly doesn't have enough lows for the size of the room. It's a warehouse with tons of misc. "stuff" laying around, and impossible to back it against a wall to amplify the lows. I've boosted the lows on my basses (US Spector, Jerzy Drozd Mastery VI, and Lakland DJ), as well as on the Purity, but I still find I don't get that low-end thoaty punch. At best, if I crank the lows, my tone ends up getting muddy. Don't get me wrong...I love the voicing of this cab, as it makes my finger-style playing really cut through with authority. But, the lows just seem lacking, at least in this room. I'm sure it's not entirely the cab's fault, as it's got more low end than my old EBS 4-10, but just still seems to be missing something "down there". I'm not in a position to acquire another cab at this point, although trading it wouldn't be as much as a financial strain. The trouble I have trading it is knowing what I'd be giving up, and wondering if it's not entirely the room's fault. So, what do I do?
