With a bonus query!! 1) I recently came into possession (legally, of course) of a GK 400RBIII. I do mostly 3- and 4-set shows, and am wondering what I do with the amp during breaks. Turn it off? Mute it? Yell at it? I know there's a cooling fan in there somewhere, so that's why I need your expertise. My old BA-115 I simply turned off on breaks, but this rig may need some gig TLC. 2) I'm hearing good stuff re the Avatar 2/12" (punch, with a solid bottom, etc.)...would that be enough (RBIII rated 240 watts at 4 ohms) for the medium-sized rooms I usually play in? 3) Thanks!!
