I did a search through the search function, so please forgive me if I just suck at using it. My current rig is a Fender Jazz through a GK 800RB into Peavey 810tx. It's a monster, great tone, and LOUD. But, the 810TX is getting to be a real pain loading in and out all the time. Also, I've been looking to get something with a little more bassy. I play in a loud post-hardcore band and also a Surf band. I thought about getting the Ampeg 410hlf, but what I'm curious about is, what kind of rooms would the Ampeg 410 not be suited to fill? How big a room before I would need to have an 810 or so? I know that a lot of people say the cab size doesn't really matter, that a PA will push everything, and I know that's true, but I'm just trying to get an idea on whether downsizing is a good idea or not. A lot of the places we've played recently have not mic'd the bass or anything, so that's why I'm wondering.
