So, I'm gonna get either the 22 calibre or the 44 magnum to use as a back up amp, and I was wondering if the 22 will be loud enough for pub/club sized gigs un-mic'd? Plus any opinions on the two items in general would be helpful.

Cheers, josh

I have the 44 magnum and it is surprisingly loud. I'd say it would probably be loud enough for most small gigs through a 4x12. You don't want to have to crank it all the way though or it'll get a bit squelchy, so you'll wanna make sure your set up accounts for that if you do use it for gigging.
