I've had a few with varying degrees of quality! I'm usually so delighted not having to hump gear that I don't mind if it's a shoe box with a drawing of a cab on it.
The most shocking one was a lovely looking old Carlsboro combo. It kind of looked a bit like a cross between a rolltop desk and a cooker and either would have sounded better. I assume I was the last person to use it before the trip to the skip.
Again my gear was in the car but I was out of there so easily and quickly. Get paid, get out and don't hurt your back!
