How loud can this cheap amp get? Enough for a medium-sized gig? (say, enough to fill a community gymnasium/basketball court) Also, any other kinds of amps that come in a similar-sized package? Edit: So this question was posed because I need to upgrade my rig to do medium-sized gigs. I'm hoping to snag a 800RB for less than $200 on Ebay...I'm looking to get just one cab for it, since money is short. I'm thinking I'll get a 2x12 cab at 4 ohms, and add in a 2x10 8ohms cab later for the high channel/large gigs. The question next being, what's a 2x12 cab at 4 ohms that I can get used for ~$300?
