Somewhere - maybe here - I read that one of Hendrix' Plexis (with an original Hendrix tour stencil painted on the amp) was seen in the amp area at the PRS factory. It might've been around the time the HXDA was discontinued. My memory is vague on this.
I have no idea what that means in terms of PRS products.
From what I can tell, the amp he's using in the recent videos is an HXDA that seems to work like mine, and sports the same switching options. As they did with the McCarty, PRS will occasionally reintroduce products, some with a slight twist on the predecessor.
Until they release this thing (if they release it), it's anyone's guess.
