I bought a crate cab around 12 years ago that came stock with brit vintage 30s (they were badging that on the front) and they were still owned by st lous at that point. Still have the cab, still sounds good. IIRC they had the power block out either shortly after or at the same time, but I can't remember. I remember the XXX was a fairly new thing at the time, playing one and not liking it.
Of course, it also took my noob ass a month to figure out that said cab was wired out of a phase. All well, chalk that up to nooby mcnoobyness.
I haven't been impressed with anything they have done in the last 8 years.
