I've never been much for chasing the latest hotness in amps. I mean, I still think my (now ancient, but revolutionary <heh> at the time) first-gen Peavey TransTube can sound pretty good. The most 'exotic' amp I own is the Fender I snagged from @LK155 which came complete with the @yoslate funk. Until two weeks ago, I hadn't actually pulled a guitar out of a case in nearly six years. When I did, I DI'd it in to my audio interface and ran it through whatever NI's pseudo-amp thingy is (GuitarRig? Something like that). Amps just don't...move me.
All that being said, it bums me out when a small- to mid-sized business folds up. Especially one more-or-less local. Even more especially when there are health challenges. But, being as none of us ever get any younger, I suppose that's just the way life goes. Good on him for realizing health is more important than many realize. Without health, what do you have, right? The thing that really stands out for me--and I'm not and have never been a customer, obviously--is the transparency. I can't count how many threads I've followed over the years where a small luthier, amp house, pedal guy, that dude making analog tape delays somewhere in the Midwest, etc. has taken customers' money and disappeared with nary another word. Dude just lays it out there, and I think that's respectable.
Don't know George Metropoulos, but I wish him the best of health and a more-than-decent shot at happiness.
