I built this to test some theories.
The jerk at the local music store wouldn't let me place his precious new Marshall stacks on this, and ran me off. I can't really blame him for being so small minded, but I got mad anyway, and it was a bad scene. I'm never going there again, and I guess he's glad about that too.
Still working on other ideas for large setups, with wheels for easy transport, based on the plywood backing idea.
I'll offer some more details and Ideas as I go. God Bless.
Step 1: Various Set Up Angles.
Step 2: I Know, It Looks Like Crap.
This uses two 6 ft. long 4x4 posts, and two 3/4" steel poles, about 5 ft long, for the legs.
Then two more poles shoved into a hole at the top to extend the length of the frame.
Also, notice the two small 1/2" diameter poles at the bottom to stop the bottom cabinet from slipping out.
Step 3: It Takes Two of These.
Custom build it according to the size of your rig. The length of the poles determines the tilt angle(s) you want and the floor space it takes up. The poles can be made surprisingly short, but if they're too short, it can tip backwards.
It's pretty stable as is, but the base board could be slightly longer to provide more side-to-side stability.
Step 4: Easy Set Up, Breakdown, Transport.
This all breaks down easily to fit in my little car.

Whaddaya want for nuttin', a Rubber Bisquit? Bow Bow Bow.
Step 5: Some Detail About Drilling the Holes.
