They're new, and as far as I know, only the Backline 115 was available before the new GK lineup, so has anyone tried the smaller combos? Since they're the same circuit as the 400RB, my head of choice, I figured they might be worth looking at for a small, portable rig. Any input on the 70W GK Backline 110 or the 100W 112? How much do these puppies weigh? I've heard that they fart a bit with active basses? Dan, shed some light on this?
