I see a lot of people buying an extension cab for these. I'm just wondering, is the combo on its own capable of being used for gigs.

Yes. It depends how loud you need to go, but the combo on its own is plenty for me. On the last gig the master volume was at about 10 o'clock - plenty left in the tank. You could always add a cab later if it's not enough
