Lets face it guys, there are so many amps on the market, and they all have their unique sound so there isn't any one amp that is perfect for every situation. It's the combination of guitar>amp>speaker(s) that provides the sound as well as the playing style of the guitarist. Almost any of the possible combinations will work in certain situations but none of them will work in all. You have to know what you want to hear, then try enough of the possibilities untill you find what it takes to get "that sound."
For me, the guy who shows up with the badly set up guitar with dead strings, a half dozen efx pedals, and an amp big enough to play at an outdoor concert (and wants to crank it wide open) is the hard guy to record. Small amps and polished musicians are much easier.
