I know this is an old topic, but I really like your build! I was also wondering if you had any tips on bending Plexi such as you did. I love the waterfall control panel.
This is always the most stressful part of my build. Every cab I've done has had a wrap-around plexi cover for my CP. This time I made it all the way through on the first piece. I went deadly slow and made sacrifices to Murphy along the the process by occasionally torching myself... totally worth it.

Thanks! Okay, so as you can see I had the panel all the way off and bit of plexi the right width but longer than a needed. Really that part is optional, but it makes it easier to clamp. When you're done you can just hit the sides with a flush-trim bit.
So what you wanna do it get the wood panel all done and rounded out the way you like it. Clamp the plexi to the panel and then heat the plexi. Recommend using a heat gun but a propane torch can work if you keep that flame moving super fast - else you'll bubble or yellow the plexi. Move the heat back and forth over the length for even heat and don't start bending until the plexi droops under its own weight. If you need a bend past your CP, like I had, then do that with a dowel rod of the right radius if it's smooth, or if it's a sharper angle just use the edge of a table.
I keep a clean piece of MDF to help push my bends. I'm going over these hillbilly techniques because I figure you, like me, don't have a bending table. Anyway, once you do your bends, I recommend doing them over two or three heat sessions. Don't try to finish the bend all at once or you'll get too much pull, then edges, and it'll get out of whack. Just go slow and keep clamping your way around.
Do not route your button holes until after your bends are complete or they won't match up.
