I'm strongly considering getting an Avatar 212, since I have a 5-string bass on the way, and I'm not digging the sound of my Hartke 410XL by itself right now. I have a GK 400RB head which I am not going to upgrade any time soon, due to financial (wife) constraints (she's still getting over the Lakland DJ5 purchase). If I can talk her into getting the 212, should I get the 4 or 8 ohm version??? The way I see it, I have two options: a) get the 8 Ohm cabinet, which would allow me to run both it and the Hartke off the GK (though I doubt this would sound very good) OR b) get the 4 Ohm version, and run just it off the GK. Maybe sell the Hartke to make the wife happy, though I doubt I'd get much for a 410 XL from circa 1990. One more thing. I will NOT be gigging with this rig, at all. It's strictly for at-home use, and I don't turn it up loud EVER (I've got a kid). At some point, I might like to get a new head, but not for a while. Thanks!!!
