People gripe about how heavy the Twin reverb is, but I almost never see a complaint about how heavy the Vox AC 30 is. They are both 2x12's, so the dimensions are pretty much the same. Current specifications for weight: Twin Reverb: 69 lbs. AC 30: 71 lbs. OK. That's only a 2 pound difference, but the Twin is slightly lighter. So why do I read all the whining about how heavy the Twin is and almost none about the AC30?
