As the title says. I've been looking at the GK 800RB, but doesnt look loud enough for medium gig-large gig situations. ANy other suggestions?
Honestly, I have a 700RB and it's more than loud enough for any of my gigs. If you need more power than that, you're most likely going to be going into the PA anyway, so I honestly wouldn't worry.
A second hand head, a peavey tour 700 should come in there.
I've seen people gig with 800 rbs and they are definitely loud enough.

Go used. There is plenty of bang for your buck on the used market.
