i need to know if this will hurt any of my rig in any way. im currently using a tech21 landmark 600 head (600w@4ohms, 400w@8ohms). im going to be running it thru 2 aguilar 115s. but im thinking of adding a poweramp (probably tube) to my rig. is that ok since my head already has a power amp? would i just run it thru the fx loop?
