Ever see a fridge or even a Showman with no tolex on the side? Just bare wood? Tolex holds up better?
I have decades old rat fur that looks brand new and it's been gigged. That tolex didn't last 3 years.
Yeah clean your gear. Sit your cab on beer soaked carpet and in a cig filled room and expect what? LOL Your lungs look worse than your cab but they are self cleaning.

Sort of.
I like the look of classic gear but it wasn't robust.
Plus there were different grades of rat fur.
What becomes commercially available doesn't denote superiority or evolution.
Bed liner is okay until you hit the cab on a corner and transfer some paint.

Play any house concerts? Do the above and don't get asked back. Nice cordura cover on a ratfur cab? Perfect.
Which brings up shock absorption. Protecting your gear in another way.
Nesting corners or chrome? Ever get hurt on a loosely swinging chrome corner on an SVT cab?
Meanwhile I remember when "black" tolex was the new thing.
