UK and US customs have no comparisons. in UK if customs finds AS they will let it through if it is a personal use quantity of 3 months approx. while US wont let through a single amp. secondly if UK customs find out suspicious amount of gear they will send addressee a letter to justify it to them, and if he satisfies them that its for his personal use they will give him back his gear with some tax, making it legal. its nothing like US. thats why gear is cheap in UK.
