My Fender Super Champ X2 is a certain never ever sell. I'm sure I'd feel the same with the original XD.
There's a slight possibility the Tweaker 20 might go up for sale or trade some distant day, but the tonal range and quality would make that a not so smart move, especially when you can change tubes to shift it deeper into various territories, like Marshall and Fender.

I've realized more or different guitar gear won't do as much for me as I'd like, so I've become very happy with everything I have. Time to work more on the "engine" (me).

Ah, but a really nice keyboard, however...
