back in the old days (late 70's) I was looking to buy an amp because my group was getting a lot of dates. I would walk into a guitar shop, scan the amps quick, pick one or two and try them out. And the first 15 seconds of this first song was what I played. Then I would try the first 7 seconds of the second song. If the amp couldn't do this - with less than a minute of knob-fiddling - I moved on. Not surprisingly, I ended up with an Ampeg V4. It was heavy; it was loud. But when I played it, I felt like somebody!
