I'm currently straining under the weight of my 6-space rack (Furman PL-Plus, Sabine 1600 tuner, Sennheiser wireless, BBE BMax, QSC PLX2402). Also, for smaller gigs, I'd like to be able to use the Furman, Sabine & Sennheiser units with a smaller amp -- but taking them out of the rack every time isn't very practical. So now what I'm thinking about is getting a couple of separate 4-space rack units -- 1 for the BBE + QSC, the other for the accessory equipment. A few questions: 1. Is anybody else doing this? Are there pros / cons I should be aware of? 2. Are there any racks designed specifically with such stacking in mind? 3. Are there any racks with a "footprint" (i.e., at the bottom) less than 19" wide. I realize that the rack itself has to be 19" wide, but I'm hoping someone makes one with small feet or some such that are less than the full 19". My Schroeder cab has a space of about 18" between the edges of the plastic corner protectors -- narrow enough that a 19" rack won't fit between them, but wide enough that it can't rest comfortably on top of both of the either. Any suggestions most welcome!
