It's no big deal. Honest. It's not. As Richard's post shows, shipping instruments cross-border is more problematic, in either direction.

You might be asked about it, but you're not going to be refused entry on some kind of vague suspicion. Just tell the truth, or lie convincingly, depending on what the truth really is! (If you need to re-invent the truth, just have your story straight before you talk to them, so that you can believe it yourself.)

The notion of having an instrument in each country is just plain ridiculous.
