Hi All, I just recently received an Amp stand for Xmas. Problem is, I've never used them so I am a little reluctant to use it (my daughter was so happy when she gave it to me). I always had my rigs on the floor (2-4.5xl or 2-4x8's). Lately i've been using my mini rig (GKMB200+GKMBE115) or a 4x8+115(1001rb). Always thought my cabs needed to be on the floor. I'm presently trying to use the amp stand now but seems like its missing ooomph. Am I missing something raising my cabs off of the floor? Please advise.
