I'm not sure how I did it, but the weight of my rig keeps getting heavier. I had a 4 space rack and then replaced it with a 6 space. Since I had more space, I bought more goodies. Now, I'm going to change out my amp to a Mackie 1400 which weighs about 40 pounds and sell my Ampeg B2R which weighs 15 pounds. What does everyone else do to keep the weight down? Wheels or use two smaller racks?
