Agree to disagree - it's bad enough when "they" simply take the $ and change the symbol to a £ - this is way beyond that (as are the pricing of all SBMM instruments). I have heard it said that the EU uptick is because SBMM insist on having all their instruments made in Indonesia (or wherever) shipped back to USA for QC checks then distribute from there. If that's true, then it's unnecessary double handling which we end up paying for, all probably to placate a few local racists who wouldn't buy an "import" bass unless it's been checked for ebola or something by a fellow countryperson who's automatically better at their quality assurance job than some foreign brown person.
Also - 20% import duty is way off the mark, it's about 5%. I forget precisely what it is, but it's definitely a single digit, not 20.
