This is one of those times when I LOVE saying I told you so.
When I started this thread, I'd only had a chance to mess around with a few of the mixes and speakers. I spent some more time today, making my own mixes in CL3, and trying a bit of the room and even "rear of cabinet" positions.
This cabinet sounds fantastic. Not too big, not small, a little bit of wood...just great! And I'm using the condenser mic where I wasn't before; that Gefell is a wonderful mic, and it doesn't sound brittle like so many condensers do.
The thing that is most striking to me is that I can choose something based on the description, and once you get what Kevin is describing, it makes for a pretty predictable set of choices; the only thing that changes is the speaker itself. And the speakers sound like I expect them to.
Most versatile cab pack I've heard so far, by a serious long shot. For $49, it's a genuine bargain. Really great work, Kevin!
