Ok guys, I know this is probably all over TB but I've been looking & can't seem to find it. My pf500 just died on me, the board was bad:/ It was a nice head but now I'm looking at something with a little more oomph(sp?). I'm leaning towards the SVT 7 pro, does anyone have this to tell me how tubey it sounds? Also, will someone please tell me what a tone shelving eq is?? In terms of the LH1000. Again, sorry for beating this topic to death
