Sorry for the confusion, it's my ignorance talking. I assumed setup meant "anything that is relatively easy to modify on a guitar." So a setup is only the action based on the height of the bridge? The other would be, what? The build of the guitar?

I guess what I'm wanting to find out is anything/everything that makes a guitar more suited to one style over the other. Next time I go looking for a guitar I don't want to mess with any that wouldn't suit my style. And once I do have it, what can I possibly modify to make it easier to play and/or sound better.
