I bought a GK 212 neo a while back (the first version, a little skinnier and taller than the newer ones) as a lightweight alternative to my bigger cabs. Even though it's a neo, it's still pretty darn heavy. Specs say 65ish, but it feels heavier. I find myself bringing my NV610 to gigs, because I find it easier to move than the GK. A friend of mine loves 12's and offered me two of his Ampeg 210av's for my 212. As far as money is concerned, it seems like a fair trade on paper. I know the GK is a heavy duty cab, not so much the Ampeg. Also, I know the power handling on the GK is much greater (I've read gk's ratings are more accurate than ampeg's). I have an ashdown head (575 watts), would I be beating the two ampegs up if I used them for a practice/small show rig? Is this a good trade?
