I took my Ultra out for its first live use this past w/e and I was stumped during setup because I didnt know where to put my rack. I normally put my rack on top of my 4x12 but I'm using the QSC HPR 122i. I thought about just sticking the rack on the floor but then I couldnt see the AXE tuner patch...I eventually balanced it on the top of a bar stool, but there has got to be a better way...what are you guys doing?
