A Glasstone Lil G cab should easily work for what the OP described but its more of an all around cab than a Gospel" one. There are happy owners who don't play gospel.
I play more finger style and in a variety of genres, it kills for that TOO.

The Faital Pro twelves handle the mids fine and while you can dial in sizzle you aren't stuck with it. That's not how they're voiced. If they were I doubt the folks use them for other instruments like uprights, keys and guitar or recorded music would dig them too. They sound accurate AND take EQ well.
So far most have only needed one 212 Lil G to cover what usually takes a pair of 1-12's to do, all in a box the size of a 1-12.
