This is a great amp stand and is stable for smaller combo amps
"Find" yourself a plastic Milk crate
Determine the angle you would like your amp to sit at and draw it on the side of milk crate with chalk
I used a large metal Carpenter;s square to draw on the chalk line
Cut with a jigsaw and you're done.
All your excess chord will sit in the bottom and you can feed them out thru the back
