@thor If you have a music store nearby I would suggest hanging around and paying attention to what the different musicians buy. With guitarists it's rather simple, they will go for the thicker strings or the very thin strings along with a thicker pick than normal. Ernie Ball Strings or better and they will probably talk about what they have and play. Drummers might be harder to find.

It's usually the equipment and tools that will be good indicators. If I hear SemiHard Body, that's almost exclusively Rockabilly and Jazz. That's also an extremely expensive guitar.
