It’s not fancy, but it’s dirt cheap, quick and solid............cinder block with board shelving between them. You can go wide or straight up depending on your setup.......and wife. You can paint or stain the boards, even paint the block to dress it up for the time being. It will hold anything, even your back-breaker amp. It’s temporary and when you don’t need them anymore you can reuse them for some other project or toss them at very little loss. Don’t cut your cables, one day you’ll need that extra couple feet and have to buy a new set..........Do not stack gear on gear or put them in an enclosed cabinet. Heat kills electronics faster than just about anything, especially that monster amp of yours, they have to be able to breath. Do whatever it takes to get Mamma on board. In the long run having her on your side will make the hobby much more enjoyable for both of you............Take your time, you don’t have to get everything "right" this week............I’ve been playing with my stuff for 45 years, it’s part of the fun of the hobby.
