I’ve had high dollar archtop guitars, delivered across the BC border by owners who sold them to me. They don’t declare anything, namely because the guitars were made in America. I’ve driven high dollar amplifiers across the border myself, and simply expressed I was sampling it against an audiophile’s amplifier I was considering in trade. Yes I lied. Lying is what we humans do. I lie, you lie, everyone lies. Since the amp was made in America there’s no duty because it’s originally made here. But if you tell an unconvincing lie, be prepared for consequences.
