I replaced my old analog 6AL back in 2003 w/ a Digital 6 and it had a high end misfire. Sent back to Summit and they sent me a new one...same thing. Swapped my old 6AL back in and the problem went away. Got a refund from Summit. I'm still running the old 6AL.
I keep resisting the urge to go w/ one of the new programmable 6AL-2 boxes.
