Sounds like a hassle, but I can understand why you’d want to. It’s part of your instrument, afterall.

You might want to consider, though, that you probably won’t be playing in one place (unless you are in a lounge band?). So your amp is going to get schlepped back and forth all over the ship by the tech crew. Tech crews are usually great, but you get the picture. They won’t cover any damages to your amp for that kind of stuff. If I were you I’d keep it safe and keep it at home.

If you really want to bring it though, I don’t think they could stop you.
