Out this way a lot of amp stuff enters the US via Halifax, Montreal, and 
Windsor with nary a peep.

It is quite simple for a Made In The USA label to be made on your PC and 
placed over (or remove the original) and the opened box (or unboxed) amp to 
be driven thru as personal property.....no reason needed.
There are several variants possible.
