Some additional thoughts...
When I try out guitars, I don't care what amp I am using.
Why?
I'm probably going to have the guitar much longer than the amp. This may not totally be true but, for so many players, it applies. I may try it on a couple of different amps.
It may be that I am less concerned about the amp because I kinda know my tastes in pick ups and tend to look at instruments that have those pick ups or understand that I may need to invest more in to pick ups that are a match to the instrument as I want to hear it.
Easy for me to say...I haven't bought a new electric guitar in a while but I guess when I have done my purchases in the past, I kinda knew where I was going and what I needed to get there.
So, there's a 'non-answer'.
