I have a thread on Marshall's own support forum and have been back and forth on another one. They keep claiming that they are there just "talk to your dealer"
I've had mine on backorder since August.
I'm going to start looking for another amp at some point, I doubt I ever buy a new Marshall again, at least in this price range (which isn't exactly budget, but not boutique either).
Shame people can't get them because it takes the amp to a whole new level. Hate to rub salt - I never thought I'd use the classic channel but I'm flipping between modes and channels all the time and when you add in the 2 masters it's like having several amps and extra pedals at your feet. I also spend a lot more time using the out of phase sound on my LP. Still loving it.....
